1 Helm: the incremental completion framework
1.1 Requirements
1.1.1 install software on the OS
In order to use features on live grep (see Section: use helm to find/open files), you need to the following apps, if you need to use:
grep
: the default grep on Linux/Unix;ack
orack-grep
: the improved grep (OS X:brew install ack
)ag
: a faster grep fromthe_silver_searcher
(OS X:brew install the_silver_searcher
)
1.1.2 install packages on Emacs
Adding a header for the exported .el
file.
;; ================================================================ ;; /Helm/ as the main completion system ;; ================================================================
Install the additional packages to support the helm
package
;; Install required packages for more functions (setq custom/helm-packages '(helm helm-core)) (custom/install-packages custom/helm-packages)
1.2 Basics configurations
;; configuration for /helm/ (require 'helm) (require 'helm-config)
semantic-mode
in CEDET causes M-x gdb
hangs emacs in Mac OS X!
Since the default C-x c
is quite close to C-x C-c
, which quits Emacs.
Changed to C-c h
(labeled by <helm-prefix>
in our later description). Note:
We must set C-c h
globally, because we cannot change helm-command-prefix-key
once helm-config
is loaded.
List of basic keybindings in the helm sessions:
<tab>
,C-i
orTAB
: run persistent actions;C-z
: list available actions;C-o
: switch between helm sources (e.g. jump from the historical list to the current list).
;; Basic keybinding: (global-set-key (kbd "C-c h") 'helm-command-prefix) (global-unset-key (kbd "C-x c")) (define-key helm-map (kbd "<tab>") 'helm-execute-persistent-action) (define-key helm-map (kbd "C-i") 'helm-execute-persistent-action) (define-key helm-map (kbd "C-z") 'helm-select-action)
More basic settings and start helm
mode:
;; More basic settings: (setq ;; open helm buffer inside current window, not occupy whole other window helm-split-window-in-side-p t ;; move to end or beginning of source when reaching top or bottom of source. helm-move-to-line-cycle-in-source t ;; search for library in `require' and `declare-function' sexp. helm-ff-search-library-in-sexp t ;; scroll 8 lines other window using M-<next>/M-<prior> helm-scroll-amount 8 ; helm-candidate-number-limit 500 ; helm-move-to-line-cycle-in-source t helm-ff-file-name-history-use-recentf t) (helm-mode 1)
Control the way to split and resize the helm buffer window:
(setq ;; default way to split window ; helm-split-window-default-side 'right ;; adjust the max height for helm buffer ; helm-autoresize-max-height 50 ;; auto-resize buffer to fit candidates (disble golden-ratio) helm-autoresize-mode t)
1.3 Functionality
1.3.1 enhance Emacs basic functionality
<IP_ADDRESS> use helm to run M-x
(global-set-key (kbd "M-x") 'helm-M-x) (setq helm-M-x-fuzzy-match t) ;; optional fuzzy matching for helm-M-x
<IP_ADDRESS> use helm to deal with mini-buffer
(global-set-key (kbd "C-x b") 'helm-mini) ;; enable fuzzy matching (setq helm-buffers-fuzzy-matching t helm-recentf-fuzzy-match t)
<IP_ADDRESS> use helm to find/open files
Default keybinding: <helm-prefix> C-x C-f
; in this session, C-c i
will insert the
current absolute path into the current buffer. Here we rebind the key to
overwrite the default find file action. And by setting
helm-boring-file-regexp-list
to avoid showing useless temporary files.
(global-set-key (kbd "C-x C-f") 'helm-find-files) ;; skip meaningless files, e.g. .DS_Store (setq helm-ff-skip-boring-files t) (delete '"\\.bbl$" helm-boring-file-regexp-list) ;show .bbl file (add-to-list 'helm-boring-file-regexp-list "\\.DS_Store$") (add-to-list 'helm-boring-file-regexp-list ".*\.synctex\.gz$") (add-to-list 'helm-boring-file-regexp-list ".*\.url$") (add-to-list 'helm-boring-file-regexp-list "\\.dropbox$") (add-to-list 'helm-boring-file-regexp-list "Icon.*") (add-to-list 'helm-boring-file-regexp-list "#.*#$") (add-to-list 'helm-boring-file-regexp-list "\\.out$")
<IP_ADDRESS> resume the previous helm session
Keybinding: <helm-prefix> b
<IP_ADDRESS> use helm to show "occur" (see helm-swoop for better functions)
Keybinding: <helm-prefix> M-s o
1.3.2 show history of ring, register and shell command
<IP_ADDRESS> use helm to show kill-ring
This is to list all entries in the king ring that are available for C-y
.
(global-set-key (kbd "M-y") 'helm-show-kill-ring)
<IP_ADDRESS> view the local/global mark rings in helm
Default keybinding: <helm-prefix> C-c SPC
;; use helm to show the mark-ring (global-set-key (kbd "C-c h SPC") 'helm-all-mark-rings) (global-set-key (kbd "M-g SPC") 'helm-all-mark-rings)
<IP_ADDRESS> use helm to view Emacs registers
Keybinding: <helm-prefix> C-x r i
Functions:
[F1]
insert register content into buffer[F2]
append an active region to current content in highlighting register[F3]
prepend an active region to current content in highlighting register
;; use helm to show the register (global-set-key (kbd "C-c h x") 'helm-register)
<IP_ADDRESS> use helm to show eshell command history
;; use helm to show /eshell/ command history (require 'helm-eshell) (add-hook 'eshell-mode-hook #'(lambda () (define-key eshell-mode-map (kbd "C-c C-l") 'helm-eshell-history)))
<IP_ADDRESS> use helm to show shell command history
(define-key shell-mode-map (kbd "C-c C-l") 'helm-comint-input-ring)
1.3.3 use live grep in helm
Helm grep is a Helm implementation of the grep command, which searches a text file for lines matching a regular expression.
Quick view of useful commands: under C-x C-f
session,
C-s
orM-g s
: usegrep/ack
to match patterns in the current buffer;C-u C-s
orC-u M-g s
: usegrep/ack
to match patterns any files with the same extension in the current folder;M-g a
: useag
to match patterns in all files in the current folder.C-u M-g a
: select extension types before runag
or, globally, use M-g a
that run helm-do-grep-ag
.
Suggested practice:
- use
ack
(C-s
) to grep files: the current file, or the files in the current folder when the cursor is on the directory (i.e. the top line of helm-find-files buffer); - use
ag
(M-g a
) to grep the directory: recursively grep all files in the current directory - if you want to grep files with a specific extension, use
C-u C-s
.
<IP_ADDRESS> Usage
From helm-find-files
(<helm-prefix> C-x C-f
), open the action menu with
C-z
and choose grep. A prefix argument will launch recursive grep. You can
also launch grep directly with (C-u) C-s
or (C-u) M-g s
(i.e. helm-ff-run-grep
) without switching to the action menu.
;; set global-key for function: =M-g a= in session of =C-x C-f= (global-set-key (kbd "M-g a") 'helm-do-grep-ag)
<IP_ADDRESS> Marked files
To grep marked files, just mark some files with C-<space>
and launch
grep. Marked files can be from different directories.
<IP_ADDRESS> Recursive
Go to the root of the directory you want to grep in, then hit C-z
to open the
action menu and choose grep with a prefix argument (C-u
).
You will be prompted for types of files to search. Wildcard syntax like \*.el
(which searches only files ending in .el
) is allowed. With ack-grep
you will
be prompted instead for ack-grep types, see ack-grep documentation on how define
types in your .ackrc
file.
By default, the extension of the file at point is used when the cursor is on a
file name. If the cursor is at root of a directory, all the file name extensions
found in the directory and not matching the variable grep-find-ignored-files
are inserted into the prompt.
<IP_ADDRESS> Highlight results
By default, Helm applies its own highlights to matched items. However, it may be
better to use the backend to highlight result with ANSI sequences. This can be
done by customizing the helm-grep-default-command
variable.
grep
:
(setq helm-grep-default-command ;; ~grep~ "grep --color=always -d skip %e -n%cH -e %p %f" helm-grep-default-recurse-command "grep --color=always -d recurse %e -n%cH -e %p %f")
ack
:
(setq helm-grep-default-command ;; ~ack~ "ack -Hn --color --smart-case --no-group %e %p %f" helm-grep-default-recurse-command "ack -H --color --smart-case --no-group %e %p %f")
git-grep
:
(setq helm-ls-git-grep-command ;; ~git-grep~ "git grep -n%cH --color=always --full-name -e %p %f")
ag
(the silver searcher):
(setq helm-grep-ag-command ;; ~ag~ from "the-silver-searcher" "ag --line-numbers -S --hidden --color --color-match '31;43' \ --nogroup %s %s %s") (setq helm-grep-ag-pipe-cmd-switches '("--color-match '31;43'"))
rg
(riggrep):
(setq helm-grep-ag-command ;; ~rg (ripgrep)~ "rg --color=always --colors 'match:fg:black' --colors 'match:bg:yellow' --smart-case --no-heading --line-number %s %s %s") (setq helm-grep-ag-pipe-cmd-switches '("--colors 'match:fg:black'" "--colors 'match:bg:yellow'"))
1.3.4 programming supports
<IP_ADDRESS> use helm for fuzzy matching of semantic
or imenu
to summary C/C++ definitions
Keybinding: <helm-prefix> i
Command: helm-semantic-or-imenu
This function supports most programming languages, not only C/C++. Note that, to
use semantic
, we need to turn on the CEDET's semantics module. We control
the feature on semantic
by the constant *enable-semantics*
defined in
init-features.el
.
(setq helm-semantic-fuzzy-match t helm-imenu-fuzzy-match t) (with-eval-after-load 'helm-semantic ;; default: C, python, elisp (push '(c++-mode . semantic-format-tag-summarize) helm-semantic-display-style) (push '(c-mode . semantic-format-tag-summarize) helm-semantic-display-style) (push '(emacs-lisp-mode . semantic-format-tag-summarize) helm-semantic-display-style) (nbutlast helm-semantic-display-style 2)) ;; remove the default elisp setting
1.3.5 use helm for Emcas Help page
Use helm to show help doc (C-h a
): <helm-prefix> a
;; helm for Emacs help functions (setq helm-apropos-fuzzy-match t)
Use helm to show info: <helm-prefix> h <key>
(<key>
: g, i, r
)
Use helm to do completion for Lisp: <helm-prefix> <tab>
(setq helm-lisp-fuzzy-completion t)
1.3.6 use helm to run system commands

3 Exploring large projects with Projectile and Helm Projectile
3.1 Install Emacs packages
Adding a header for the exported .el
file.
;; =============================================================== ;; Project Management via Projectile ;; ===============================================================
Install the additional packages to support the helm-projectile
package
;; Install required packages for more functions (setq custom/proj-packages '(projectile helm-projectile)) (custom/install-packages custom/proj-packages)
3.2 Package: projectile
;; /projectile/: project management (require 'projectile) (projectile-global-mode) (setq projectile-enable-caching t)
To refresh the whole cache, use projectile-invalidate-cahe
.
3.3 Package: helm-proctile
3.3.1 Enable helm-projectile
;; /helm-projectile/: browse via helm (require 'helm-projectile) (helm-projectile-on) (setq projectile-completion-system 'helm)
3.3.2 Basic commands
helm-projectile-switch-project
:C-c p p
helm-projectile-find-file
:C-c p f
helm-projectile-find-file-dwim
:C-c p g
helm-projectile-fi-other-file
:C-c p a
- Virtual directory manager
- create a Dired buffer of project files :
C-c f
- add more files to the Dired buffer :
C-c a
- create a Dired buffer of project files :
helm-projectile-ack
:C-c p s a
3.3.3 All-in-one command
Command: helm-projectile
, C-c p h
Usage: this command, by default, is the combination of these 5 commands:
helm-projectile-switch-to-buffer
helm-projectile-find-file
helm-projectile-switch-project
3.3.4 Enter project portal
Command: helm-projectile-switch-project
, C-c p p
Usage: This is the very first command you need to use before using other
commands, because it is the entrance to all of your projects and the only
command that can be used outside of a project, aside from
helm-projectile-find-file-in-known-projects
. The command lists all visited
projects. If you first use Projectile, you have to visit at least a project
supported by Projectile to let it remember the location of this project. The
next time you won't have to manually navigate to that project but jump to it
instantly using helm-projectile-switch-project
.
(setq projectile-switch-project-action 'helm-projectile)
List of actions in the session:
- open Dired in project's directory:
C-d
- open project root in vc-dir or magit:
M-g
- switch to Esell; open a project Eshell:
M-e
- grep in projects (prefix
C-u
to recursive grep):C-s
- compile project, run
compile
at the project root:C-c
- remove projects (delete marked projects from the list of known projects):
M-D
3.3.5 File management
<IP_ADDRESS> Command: helm-projectile-find-file
, C-c p f
Usage: This command lists all files in a project for users to narrow down to wanted files. Some frequently used actions that cover open, rename, copy, delete,search and other miscelaneous operations. Once you mastered the actions of helm-projectile-find-file, you master the actions of other commands as well since the actions of other commands are just a subset of helm-projectile-find-file actions. All the key bindings associated with actions are only available while a Helm buffer is active. You can think of actions as an mini version of M-x: only applicable commands are listed, and even those commands have key bindings. Prefix argument can be applied, when possible.
Open
- Find file:
RET
to open files;M-SPC
to mark files;M-a
to mark all - Find file other window:
C-c o
- Find file as root:
C-c r
Move and Reanme
- Rename files:
M-R
;M-SPC
to mark files
Copy and Delete
- Copy files:
M-C
- Delete files:
M-D
orC-c d
Search and Replace
- Grep files:
C-s
(add prefixC-u
for resursive grep) - Zgrep:
M-g z
(add prefixC-u
for resursive grep), invoking grep on cpmressed files - Locate (using Unix
locate
):C-x C-f
(addC-u
to specify locate db)
Miscellanies
- Insert as org link (C-c @): Insert the current file that highlighted as an Org link.
- Ediff files:
C-=
- Ediff Merge files:
C-c =
, when exactly two files are selected - Etags:
M-.
, invoking Etags using helm - Switch to Eshell:
M-e
- Eshell command on files:
M-!
- Symlink files:
M-S
, using absolute path - Relsymlink files: using relative path
- Hardlink files:
M-H
- Checksum file: generate file checksum and insert checksum in
kill-ring
- Print file:
C-c p
(addC-u
to refresh)
<IP_ADDRESS> Command: helm-projectile-find-file-in-known-projects
, C-c p F
<IP_ADDRESS> Command: helm-projectile-find-file-dwim
, C-c p g
<IP_ADDRESS> Command: helm-projectile-find-dir
, C-c p d
- open Dired in project's directory
- switch to Eshell:
M-e
- grep in projects:
C-s
(add prefixC-u
for recurse grep)
<IP_ADDRESS> Command: helm-projectile-recentf
, C-c p e
<IP_ADDRESS> Command: helm-projectile-find-other-file
, C-c p a
Usage: switch between files with the same name but different extensions. With
prefix argument C-u
, enable flex-matching that match any file that contains
contains the name of current file.
Variable: projectile-other-file-alist
;; adding the switch between html <-> js ;; html -> js (add-to-list 'projectile-other-file-alist '("html" "js")) ;; js -> html (add-to-list 'projectile-other-file-alist '("js" "html"))
<IP_ADDRESS> [IMPORTANT] Caching
- command:
projectile-invalidate-cache
,C-c p i
- command:
projectile-cache-current-file
,C-c p z
- command:
projectile-purge-file-from-cache
- command:
projectile-purge-dir-from-cache
3.3.6 Virtual directory manager
When in a helm-projectile-find-file session:
- create Dired buffer from files:
C-c f
- add files to Dired buffer:
C-c a
- remove entry from from Dired buffer:
C-c d
3.3.7 Buffer management:
Command: helm-projectile-switch-project
C-c p b
Usage: List all opened buffers in current project. The command has a similar
subset of actions in helm-projectile-find-file
, so once you mastered the
actions in helm-projectile-find-file
, except instead of opening files, you
open buffers instead.
3.3.8 Search in project
<IP_ADDRESS> Command: helm-projectile-grep
, C-c p s g
This is a replacement command for projectile-grep
that uses Helm
interface. When a symbol is at point, this command uses that symbol and search
at project root for every occurrence of this symbol in all non-ignored files in
project. If a region is active, use the region instead.
(eval-after-load 'grep '(when (boundp 'grep-find-ignored-files) (add-to-list 'grep-find-ignored-files "run") (add-to-list 'grep-find-ignored-directories "obj")))
Configuration:
You can specify directory to exclude when searching by customize either one of these variables:
grep-find-ignored-files
: list of file names which rgrep and lgrep shall exclude.helm-projectile-grep
also uses this variable.grep-find-ignored-directories
: list of names of sub-directories which rgrep shall not recurse into.helm-projectile-grep
also uses this variable.projectile-globally-ignored-files
: list of files globally ignored by Projectile.projectile-globally-ignored-directories
: list of directories globally ignored by Projectile.
<IP_ADDRESS> Command: helm-projectile-ack
, C-c p s a
Configuration:
grep-find-ignored-files
: list of file names which rgrep and lgrep shall exclude, andhelm-projectile-ack
also uses this variable.grep-find-ignored-directories
: list of names of sub-directories which rgrep shall not recurse into.helm-projectile-ack
also uses this variable.projectile-globally-ignored-files
: a list of files globally ignored by Projectile.projectile-globally-ignored-directories
: a list of directories globally ignored by Projectile.
<IP_ADDRESS> Command: helm-projectile-ag
, C-c p s s
Configuration:
grep-find-ignored-files

4 Source code navigation via GNU Global with helm interface
4.1 Requirements
4.1.1 Emacs packages
;; ================================================================ ;; Tag Supports in Programming Environement ;; ================================================================ ;; Install required packages for more functions (setq custom/gtags-packages '(helm-gtags)) (custom/install-packages custom/gtags-packages)
4.1.2 System commandline tools
The tagging system we used is GNU global
with ctags & pygments
supports. To
install global
:
- OS X:
brew install global --with-ctags --with-pygments
- Arch Linux:
pacman -S ctags python-pygments
(setenv "GTAGSLABEL" "pygments") (setenv "GTAGSLIBPATH" (concat (getenv "HOME") "/.gtags/")) ;; if tag system libs
To create tags, choose either way as follows:
- console:
gtags --gtagslabel=pygments

Front End
HTML5
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser.
CSS3
Stands for "Cascading Style Sheet." CSS is the language for describing the presentation of Web pages, including colors, layout, and fonts.
Bootstrap
Bootstrap is a framework to help you design websites faster and easier. It is a free and open-source CSS framework directed at responsive, mobile-first front-end web development. This webpage was made using BootStrap V5(beta).

JavaScript
JavaScript is a dynamic computer programming language. It is lightweight and most commonly used as a part of web pages, whose implementations allow client-side script to interact with the user and make dynamic pages.
NPM Packages
NPM is a node package manager. It is used for managing dependencies of various server side dependencies.
NodeJs
Node. js is a platform built on Chrome's JavaScript runtime for easily building fast and scalable network applications.

Data Base and Cloud Providers
MondoDB
MongoDB is a document database, which means it stores data in JSON-like documents. We believe this is the most natural way to think about data, and is much more expressive and powerful than the traditional row/column model.
mySQL
MySQL is a relational database management system based on SQL – Structured Query Language.
Heroku
Heroku is a platform as a service (PaaS) that enables developers to build, run, and operate applications entirely in the cloud.

@(launchForm: Form[controllers.RawQuery])(implicit messages: Messages) @import helper.RichHelpers._ @templates.main("Panop") { @templates.headers { @if(launchForm.hasErrors) {
Some internal search systems for website are simply not accurate enough. Often, external indexed-based search tools are not sufficient either, especially when the data is moving fast, or only specific subsets of websites are targeted. One way to avoid this is to do online analysis and search: this is what Panop is for. Panop will provide you a simple interface that allows you to select the target of a search and its settings, as well as domain boundaries and search depth. It will then return you a list of URLs matching your requirements and allow you to browse through it. Panop is a command-line-based tool or a web-based tool.
A query is in disjunctive normal form (examples: 'A' or 'A' AND 'B' or ('A' AND 'B') OR ('B' AND 'C'). It is also possible to avoid results containing some keywords (examples: ('A' AND 'B') - ('C' AND 'D') where pages containing C and D will not be returned, etc.).
This will be the entry point of the search, which will expand from there (example: http://www.crossstream.ch/historical).
If a page A contains a link to B and a page B a link to C, then C is at depth 2 from A. This is the maximum depth from the root of the search.
If specified, all explored urls will need to be prefixed by the domain (example: http://www.crossstream.ch).
This is the list of ignored filed extensions (separated by |, i.e. in Regular Expression).
HTML tag(s) before which content will be ignored (in Regular Expression).
HTML tag(s) after which content will be ignored (in Regular Expression).
Can be either BFSMode (Breath First Search), DFSMode (Depth First Search) or RNDMode (Random).
For performance reasons, no more than @panop.Settings.defMaxSlaves search nodes are allowed.


Do not include a header.
Paste a two-column CSV, where the first column is the Name, and the second column is the Email.
Do not include more than 100 contacts.

Constance Wu feels too 'self-conscious' to watch herself in Hustlers
Constance Wu is too ‘self-conscious’ to ever watch herself in Hustlers.
The Fresh Off the Boat star admitted she ‘probably’ will never watch the popular film about strippers taking their lives back from their clientele.
‘Probably not,’ the star admitted to Mindy Kaling when asked whether she’d watch it.
‘It’s not that I don’t watch all my projects, it’s a case-by-case basis.
‘If it’s going to help my work to watch something, I’ll watch it, but if I think it’s just going to make me self-conscious about my work in the future and damage my work, then I don’t.’
Speaking for Variety’s Actors on Actors issue, the 37-year-old continued: ‘I think Destiny is in such a vulnerable… she has such a huge arc, she changes from beginning, middle to end.
Advertisement Advertisement
‘I feel like if I watch it too much, I’ll get analytical and self-conscious and it’ll affect my performance in the future. But I’m so glad people are enjoying it, and I had the best time doing it.’
Constance starred in the crime movie alongside Jennifer Lopez, Lili Reinhart and Cardi B but believes her future projects might be impacted if she watches the movie.
She also praised Hustlers director Lorene Scafaria for the natural direction she took the film.
Constance explained: ‘[She] doesn’t come from a place of, “Oh, let’s humanise this woman.” She already understands that this is how she’s going to frame her story within the context of something that you would think would have the male gaze because it’s about women who work in strip clubs.’
Agreeing with the statement, Mindy replied: ‘I remember thinking nothing felt exploitative. As [a] woman, I love seeing beautiful women dance, but the way that [Hustlers] was shot, there was nothing prurient, which I thought was really refreshing.
‘On a producer standpoint, I feel like I can’t come to these things and talk about how important it is that we have representation and then hire some white dude to direct my movie.’

NAN contains functions that convert v8::Value
s to other v8::Value
types and native types. Since type conversion is not guaranteed to succeed, they return Nan::Maybe
types. These converters can be used in place of value->ToX()
and value->XValue()
(where X
is one of the types, e.g. Boolean
) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new v8::Maybe
and v8::MaybeLocal
types for these conversions, older versions don't have this functionality so it is provided by NAN.
Converts a v8::Local<v8::Value>
to a different subtype of v8::Value
or to a native data type. Returns a Nan::MaybeLocal<>
or a Nan::Maybe<>
accordingly.
See maybe_types.md for more information on Nan::Maybe
types.

pips Red=92 White=114
(CorrectAnswer= 0/0, ErrorScore= 0)
One of my favourite sporting quotes comes from the multiple gold medal winning oarsman, Matthew Pinsent: “Lack of skill, discipline or fitness are common amongst all but the top sportspeople. Once you get to the top it is pressure, the influence of the opposition or mental toughness.”
That comment applies as much to mind games as it does to sport. We can all solve problems much more easily from the comfort of an armchair. There is no real pressure to get the correct answer and, if you get the wrong answer, there is no real penalty other than the annoyance of failing to solve the puzzle.
Back in the environment of a live tournament things are very different. Pressure comes from many aspects: the need to win to progress; the loss of potential winnings; a large audience watching your every move and finally, the clock will be ticking away the seconds.
In a recent tournament world number one, Mochy, was Black and trailed 5-6 in a match to 11. His opponent redoubled him to 4 and the pressure was well and truly on. White has twenty-seven rolls that make a five-point prime when Black’s position will become precarious indeed. Four points will take White to 10-5 and Black will have only 10% match winning chances from there. Seeing all this and knowing his opponent to be weaker than himself (when you are world number one this happens a lot!) Mochy dropped the redouble and played on from 5-8 behind.
In this instance Mochy allowed to pressure to get the better of his judgement. Analysed in the calm of a study I am sure he would have reached the correct conclusion that this is only just a redouble and a surprisingly easy take. Black is ahead in the race, has (at least for the moment) the stronger home board and has threats of his own against White’s rear checker. Attacking that checker may give him time to extricate his own rear checker.
If you add in the factor that Black will be very quick to redouble to 8 and put the match on the line then you can see how easy the take is. The problem is that under pressure the mind often only sees the negative aspects of a position and influences decisions accordingly.
In a money game the redouble would be much clearer because White doesn’t have to worry about the influence of the score. Equally well I am sure that in a money game Mochy would have made the correct decision.
So even the best in the world can succumb to pressure as many great sportspeople and games players the world over have shown. But then, that’s what makes top level sports and games so exciting to watch.

I am trying to do real....etc measurement using Allegro ACS712 module and the Voltage divider circuit explained in this amazing site.Load(40W bulb). The method i tried is, i want to combine ACS712 module and voltage divider circuit for energy measurement.
First i would like to show the reading i got:
-46.71 177.35 229.85 0.77 -0.26
-33.13 177.02 229.93 0.77 -0.19
-47.28 178.45 230.92 0.77 -0.26
-33.82 177.99 229.93 0.77 -0.19
-46.39 178.86 230.97 0.77 -0.26
-33.42 177.61 229.08 0.78 -0.19
-47.08 179.09 230.91 0.78 -0.26
-33.11 177.09 229.18 0.77 -0.19
-46.08 177.46 229.98 0.77 -0.26
Second: The voltage readings are correct(i checked with a multimeter) but the real power became negative and so as a result the powerfactor. not only these but current is also wrong as "I" should have been =(40/230)=0.17Amps.
Code for ACS712(fully functional in hardware tested) and also the emonTX code(which i changed alittle bit because i wanted to try ACS712 module :) ) are attached below.
Please help me...I want to learn !!!
(i have 20Amp model) thats 100mV/Amp.(ACS712)
Re: Real power is coming negative on a 40W bulb(load) when tried with Allegro ACS712 module and Voltage divider circuit
I suspect the power is negative because you've got it facing the wrong way, just flip it the other way relative to the wire you're monitoring, and it should swing positive. That wouldn't show up in your ACS712 sketch, because it's doing an RMS, so you'll get a positive result regardless of which way it's facing, and without a voltage signal to reference to, it's impossible to say which way the current is flowing.
I'm not an EmonLib guru, but I'm not sure you need the changes you've made to it. Before your changes, that code used a digital high pass filter (see step B) to remove the DC offset, which I'd imagine is a better approach than subtracting a hardcoded 512. You'll need to calibrate the reading. The calibration constant is the second argument you pass to current(). There are instructions in the Building Blocks section on how to calibrate.
Re: Real power is coming negative on a 40W bulb(load) when tried with Allegro ACS712 module and Voltage divider circuit
Cheers!!! After changing the hardcoded sampleI= 512-analogRead(Ipin) instead of analogRead(Ipin)-512 which you suggested(current direction sense for hall effect XD)
The Readings are as below:
45.77 47.65 245.16 0.19 0.96
45.86 48.10 245.15 0.20 0.95
46.33 48.25 246.23 0.20 0.96
45.06 47.33 245.27 0.19 0.95
46.47 48.17 246.18 0.20 0.96
45.88 47.92 245.05 0.20 0.96
46.01 48.00 245.04 0.20 0.96
45.82 48.06 245.16 0.20 0.95
NOTE: Above readings are stable closer to accurate but I am using a 40W bulb and my main Vrms=247V(code justified Vrms) and then Irms=(40/245)=0.16 (I guess, my current measurement didn't have enough samples because if my Irms=0.16 occured then my Pvi=245*0.16=39.2W(40W),Can you suggest about how to deal with this current issue for accuracy please!!).as a result my Preal is not equal to 40W and also my phasecal has to be changed(i'll takecare of it to make Preal=Pvi).
Thanks !!!
Re: Real power is coming negative on a 40W bulb(load) when tried with Allegro ACS712 module and Voltage divider circuit
After changing the hardcoded sampleI= 512-analogRead(Ipin) instead of analogRead(Ipin)-512 which you suggested
I'm not sure I want to be credited with that suggestion. I suggested you lose the 512, and use the high-pass filter that you commented out. Those using a CT have the exact same problem as you do: the signal swings around a mid-point, and that mid-point needs to be removed from the input. They've solved that with a more sophisticated solution than subtracting 512. Is there any reason you don't want to use the existing solution? You seem happy to use it for the voltage signal, but not for the current signal. Having said that, yes, flipping the sign of the current reading has the exact same effect as flipping the sensor 180°, and depending on your physical installation, may well be easier.
Can you suggest about how to deal with this current issue for accuracy please
Yep, just follow the steps here: http://openenergymonitor.org/emon/buildingblocks/calibration
P.S. You might want to verify that your 40W bulb is exactly 40W before you calibrate to it. Bulbs vary a lot.
Re: Real power is coming negative on a 40W bulb(load) when tried with Allegro ACS712 module and Voltage divider circuit
And I suggest using a resistive load much larger - one that draws a current that is about 50% - 75% of the maximum current of your CT, if that is possible - for calibration.
Re: Real power is coming negative on a 40W bulb(load) when tried with Allegro ACS712 module and Voltage divider circuit
yes, because i happen to have ACS712 module ready with me and more over the "main reason" is the CT has a jack at its end and unfortunately all my controllers doesn't have any means for jack pin to be connected. i can't buy a controller just because i need it to be connected for CT. Please suggest if you have any ideas regarding this(with some reference links to learn from).
Am working on this, will get back to you with some form of improved results. Thanks alot!!
Re: Real power is coming negative on a 40W bulb(load) when tried with Allegro ACS712 module and Voltage divider circuit
@Robert
I tried the calibration and was only able to achieve a maximum of 0.96(powerfactor) on same 40Wbulb( sorry am away from college, can't get bigger loads any time soon). Can you tell from your experience, is it possible to achieve a powerfactor of 0.99 by changing phaseCal?? As far as my search goes, i found a powerfactor of 0.97 achieved from posts.
Re: Real power is coming negative on a 40W bulb(load) when tried with Allegro ACS712 module and Voltage divider circuit
@dBc
Cheers!! after testing, i found out that both Vrms as well Irms(which i am worried about) are both correct!! and hence Pvi also should be correct. and powerfactor i am able to achieve around 0.96(but not 0.99 for some reason) and hence all readings are fine and ACS712 does its magic properly.
Do you know whether it is possible to achieve 0.99 powerfactor?(i mean is it supposed to be that accurate?
Re: Real power is coming negative on a 40W bulb(load) when tried with Allegro ACS712 module and Voltage divider circuit
I have seen a pf of > 1.0 (but that was before an error in the sketch was corrected!). You can get a pf of 1.0, and I have sometimes changed the print statement to give more significant figures so that I can see whether it is exactly 1.0. (More often, it has been 0.996 or something like that.) But I do not think you will see a better power factor with a load that small, as errors in the CT will be significant.
But you can always make your ct think you have a larger load, by having a multi-turn primary winding. Normally, the primary winding is a single turn (a straight wire) but by having many turns, you multiply the current (and so the apparent size of your lamp load) by the number of turns. For example, to test the 100 A CT at 250 A, I used a 50-turn primary carrying 5 A. But you must be very careful of temperature rise if you try that, because 50 bunched conductors carrying 5 A will get very hot very quickly.
" You seem happy to use it for the voltage signal, but not for the current signal
If you do not use the high pass filter, any difference between the true average value of the input and the number you subtract (512?) will affect the accuracy of the power calculation and the rms calculations. What you use for the input transducer does not change that. Remember that the HP filter can remove less than 1 count of offset, as it works on floating point values.
yes, because i happen to have ACS712 module ready with me and more over the "main reason" is the CT has a jack at its end and unfortunately all my controllers doesn't have any means for jack pin to be connected. i can't buy a controller just because i need it to be connected for CT. Please suggest if you have any ideas regarding this(with some reference links to learn from)."
 In the case of the YHDC range of CTs, connect only the red and white wires from the CT to the input of your controller.

Press release
Prime Minister and Business Secretary host reception with some of the UK’s top businesses to celebrate employing thousands of apprentices.
Some of the UK’s top businesses will celebrate employing thousands of apprentices and pledge to take on more at a special reception in Downing Street today (18 January 2016) hosted by the Prime Minister and Business Secretary Sajid Javid.
Businesses and public sector organisations including Greene King and the Army will celebrate employing record numbers of apprentices, while firms including Deloitte and the Adecco Group will pledge to boost their numbers of apprentices. Top employers recognise the benefits apprenticeships bring to growing their businesses and providing opportunities for young people who want to work hard and get on.
The Prime Minister will also announce that a new Apprenticeship Delivery Board will be established, bringing together some of the country’s leading business. With members from top employers including Channel 4, Barclays and Wates Construction, the board will encourage more businesses to develop quality apprenticeships. Members will act as apprenticeship champions within their sector, working with employers of all sizes to increase both the number of apprenticeship places on offer and the supply of talented candidates.
The Board will harness their experience and industry reputation to encourage others to follow their lead while also working to identify challenges that may be stopping employers getting involved with apprenticeships.
Business Secretary Sajid Javid said:
Three million more apprenticeships by 2020 means even more life changing opportunities for our young people. More than that, apprenticeships make sense for business. That’s why some of the country’s top business leaders are coming together to bang the drum for apprenticeships.
We are putting employers at the heart of quality apprenticeships so that young people get the skills they need to succeed. Today we are celebrating everything that apprenticeships have to offer businesses and young people.
Chaired by the Prime Minister’s apprenticeship advisor Nadhim Zahawi MP and businessman and apprenticeship champion David Meller, the Apprenticeship Delivery Board will include:
Chair of the Apprenticeship Delivery Board, Nadhim Zahawi said:
I’m proud that we’ve been able to put together such an exciting line up of top business leaders for the Apprenticeship Delivery Board. I look forward to working closely with them all, raising further awareness of the business benefits of apprenticeships and providing feedback on how to continually improve quality, as well as quantity.
As ever more great British businesses get involved, and with the inclusion of higher and degree level apprenticeships, we can raise the status of apprenticeships while delivering 3 million starts by 2020; a target which provides us with an unmissable opportunity to change lives, boost skills and increase productivity in the UK economy.
Latest figures show that more people than ever before are participating in apprenticeships, with further employer commitments set to follow as the government continues to deliver its promise of 3 million apprenticeship starts by 2020 .
Top employers celebrated record apprenticeship achievements and pledged to take on more recruits in 2016:
Ministry of Defence: Announced that the Army has recruited its 80,000th apprentice, Katy Houston, now a Lance Corporal, on an apprenticeship in Engineering Maintenance. More than 98% of new soldiers are enrolled on a trade-related apprenticeship during their training and the Army programme is the largest employer programme in the country. The Army includes apprenticeship opportunities such as engineering, healthcare and animal care.
Deloitte: Have committed to doubling the number of positions available through their BrightStart Business Higher Apprenticeship Scheme. The scheme will provide 200 high quality apprenticeships to school and college leavers giving them the opportunity to study technical qualifications while working.
Greene King: Have delivered on their pledge to create 2,000 more apprenticeships, taking the total number of people earning and learning with an apprenticeship at the firm to 3,300. Greene King is now working to increase the number of qualifications available to their 42,000 employees.
Adecco Group: The recruitment agency launched their first apprenticeship scheme in the summer of 2015. As a result of the success of the scheme they hope to create 50 new apprenticeships in 2016 and are committed to making apprenticeships an integral part of their recruitment strategy.
Sellafield Ltd: Sellafield Ltd will be welcoming a further 165 apprentices this year - taking the total number of young people in training with Sellafield Ltd to a landmark 550 apprentices.
Prezzo: The restaurant chain is offering apprenticeships to level 4 and is committed to ensuring that the programme is helping to develop senior managers of the future. Prezzo are currently supporting almost 400 employees through apprenticeships across levels 2 to 4.
Barclays: Barclays launched the ‘Bolder Apprenticeships’ in 2015, the first UK employer to open their apprenticeship programme to adults over the age of 24 years. Barclays has ongoing support apprenticeships and has committed to recruiting a further 500 apprentices in 2016.
International Financial Data Services: The firm celebrated their 500th apprentice joining the firm since they launched their apprenticeship scheme in 2013.
For more information or employer and apprentices quotes please contact<EMAIL_ADDRESS>For more information on the Apprenticeship Delivery Board please contact<EMAIL_ADDRESS>The National Apprenticeship Awards will be taking place in central London on 26 January 2016.
Skills and Further Education is a devolved matter, meaning reforms of apprenticeships apply to England only.
The government published English apprenticeships: our 2020 vision at Apprenticeships (in England): vision for 2020
Alongside apprenticeships young people can gain the skills they need to kick-start their future careers through Traineeship or Work Experience opportunities.
National Apprenticeship Week 2016 takes place from 14 to 18 March 2016, it is co-ordinated by the National Apprenticeship Service and is designed to celebrate apprenticeships and the positive impact they have on individuals, businesses and the wider economy.

$N$ Particle Hong–Ou–Mandel
[TP2, 2015] Let’s reconsider the beam splitter discussed in Lecture 1.
$\adop_i$, $\aop_i$ ($i=1,2$) create and destroy particles in the incoming states, and $\bdop_i$, $\bop_i$ do the same for the outgoing states. The creation operators are related by the $S$-matrix
In the following parts, give all possible occupancies of outgoing states 1 and 2, and their probabilities. The statistics of the particles are given in square brackets. Note that the states are not necessarily normalized.
- The initial state is $\adop_1\adop_2\ket{\text{VAC}}$ [Fermions].
- The initial state is $\adop_1\adop_2\ket{\text{VAC}}$ [Bosons].
- The initial state is $(\adop_1)^N(\adop_2)^N\ket{\text{VAC}}$ [Bosons].
- The initial state is $\exp(\alpha_1\adop_1+\alpha_2\adop_2)\ket{\text{VAC}}$ [Bosons].
How does the distribution in part 3 look? Try taking the limit of a large number of particles.
Equation of Motion for Density
Find the Heisenberg equation of motion of the density operator $\rho(\br)=\pdop(\br)\pop(\br)$ with the Hamiltonian
Interpret the result. Is the result changed if we introduce an interaction of the form
HBT Correlations From an Optical Lattice
In (Fölling et al., 2005), bosonic atoms were initially prepared in an optical lattice in a Mott state:
where $\adop_{i}$ creates a particle localized at site $\br_{i}$ in the lattice, with (let’s say) Gaussian wavefunction
(a) raw image (b) density of an atomic cloud following expansion from a Mott state. (c) and (d) noise correlation signal extracted from the same image. From (Fölling et al., 2005).
Show that the correlation function of momentum state occupancies is
where $\tilde\varphi_{i}(\bp)$ is the Fourier transform of the spatial wavefunction, and $:(\cdots):$ denotes normal ordering of the operators between the colons. Evaluate the Fourier transform and explain the structure of the noise correlations in the above data.
Mean Field for Bose–Hubbard
For the Bose–Hubbard model, let’s try a variational wavefunction of the form
The N$^{\text{th}}$ Mott states has a fixed integer number of bosons per site i.e. $c_{N}=1$ with all other coefficients zero. We identify the superfluid phase with the region where more than one $c_n$ is nonzero, meaning that the bosons can move around.
-
Find the expectation value of $\cH_\mu = H-\mu N$ using the above wavefunction.
-
To find the boundary, use a self-consistent scheme. First assume that $\langle \aop_{i}\rangle$ is small. Then use perturbation theory in this quantity to see how the $c_{n}$ change to first order. Next calculate the value of $\langle \aop_{i}\rangle$ that results. The gives an equation with $\langle \aop_{i}\rangle$ on both sides, which can then be cancelled to give an equation determining the boundary between the phases. Plot the boundary as a function of $t/U$ and $\mu/U$. Does it agree with the boundaries found in the lectures when $t/U$ is small?
Bose–Hubbard With Spin
Consider the Bose–Hubbard model with spin
where $\Nop_j = \Nop_{j,\uparrow}+\Nop_{j,\downarrow}$. If we have a $\nu=1$ Mott state, how does the behaviour at $t/U\ll 1$ differ from the Fermi Hubbard case?
 Find the energy of this state.
-
The ground state wavefunction is
Find the probability distribution of the separations $x_{j+1}-x_j$ in this state. Replacing each separation by its mean value, show that the resulting density profile coincides with that of the bright soliton.
Persistent Currents Without Rotational Symmetry
A system of bosons moving on a ring of radius $R$ is described by the Hamiltonian $H=H_1+H_2$, where
is the single particle Hamiltonian, involving some potential $V(\theta)$, and
describes interactions between the particles. $\pdop(\theta)$ and $\pop(\theta)$ satisfy
In the basis of angular momentum eigenstates
$\pop(\theta)$ may be expressed
where $a_l$ annihilates a particle in state $l$. By considering only states $l=0$ and $1$, show that the Hamiltonian takes the form
and identify $\omega_{c}$ and $V_{0}$.
Introduce the Gross–Pitaevskii wavefunction
and show that:
-
The order parameter has a node for $\chi=\pi/2$. If $V_0$ is due to a localized potential, this node will coincide with the position of that potential.
-
The GP variational energy is (up to a constant, and ignoring terms lower order in $N$)
while the angular momentum is
-
A metastable minimum exists for $2U_0>V_0$ (assuming $U_0$ and $V _0$ are both much less than $\omega_c$). That is, for small enough deviations from perfect symmetry, metastable configurations are possible, and have their origin in the repulsive interactions. The point $\chi=\pi/2$ that corresponds to an order parameter with a node is then a maximum of the energy.
-
Finally, consider what would happen for Fock states of the form
This situation — macroscopic occupations of more than one single particle state — is sometimes called a fragmented condensate.
Perturbation Theory for the Bose gas
-
Find an expression for the ground state energy of the Bose gas at second order in the interaction, and confirm the ultraviolet divergence found in the lectures. This can be ‘cured’ by recognizing that a real potential as a finite range, which cuts off the integral.
-
[Harder]. The expression for the third order perturbative correction is
Show that this expression contains an infrared divergence (i.e. at low momenta). This can’t be fixed by appealing to the interaction potential, and is the reason we need Bogoliubov theory! See (Brueckner & Sawada, 1957).
Bogoliubov as Unitary Transformation
Find an antihermitian generator $A$ that generates a Bogoliubov transformation, i.e.
Hint: expand in $\kappa_\bk$. Compare the action of this transformation on the vacuum state with the form of the Bogoliubov transformation given in the lecture.
Condensate Depletion in One and Two Dimensions
-
Show that the condensate depletion in one dimension is logarithmically divergent in the length of the system, indicating a breakdown of Bogoliubov theory in the infinite length limit.
-
By assuming that the Bogoliubov modes have thermal occupations at finite temperature
Show that the depletion is logarithmically divergent in the system size in two dimensions at finite temperature.

This model allows a specified amount of heat flow rate to be "injected" into a thermal system at a given port. The amount of heat is given by the input signal Q_flow into the model. The heat flows into the component to which the component PrescribedHeatFlow is connected, if the input signal is positive.
If parameter alpha is <> 0, the heat flow is multiplied by (1 + alpha*(port.T - T_ref)) in order to simulate temperature dependent losses (which are given with respect to reference temperature T_ref).
