WebSocket Server Connector
WebSocket is a protocol that provides full-duplex, persistent communication channels over a single TCP connection. Once a WebSocket connection is established, the connection stays open until the client or server decides to close this connection. This connection is also initialized by the client, in which case the WebSocket protocol uses an HTTP request to upgrade the connection from HTTP to WebSocket using two HTTP headers, “Connection” and “Upgrade”.
For example:
GET ws://websocket.example.com/ HTTP/1.1
Origin: http://example.com
Connection: Upgrade
Host: websocket.example.com
Upgrade: websocket
This tells the server that the client needs to establish a WebSocket connection. If the server supports WebSocket, it sends the response agreeing to establish the connection using the “Upgrade” header.
For example:
HTTP/1.1 101 WebSocket Protocol Handshake
Date: Wed, 16 Oct 2013 10:07:34 GMT
Connection: Upgrade
Upgrade: WebSocket
Once this message is sent, the handshake is completed, and the initial HTTP connection is replaced by the WebSocket connection using the same underlying TCP/IP connection. Ballerina uses the same HTTP base path + WebSocket Upgrade path to upgrade the existing connection to a WebSocket connection.
Defining a WebSocket service in Ballerina
A WebSocket service is defined in the same service base path as a REST service, since this is an upgrade from the REST service.
Step 1: Add WebSocketUpgradePath
Add a base path and WebSocketUpgradePath to the service.
For example:
@http:BasePath(“/test”)
@ws:WebSocketUpgradePath(“/websocket”)
service myService {
}
If you want to connect to this WebSocket endpoint, use ws://host:port/test/websocket
.
Step 2: Add annotations to the resource level
There are several supported annotations for this release of Ballerina.
@ws:OnOpen
This annotated resource will be called when a new client is connecting to the WebSocket endpoint. If something has to be done when a new client is connecting to the endpoint, you can add that logic to the relevant resource.
@ws:OnTextMessage
When the server is receiving a text message from the client, this resource will be called.
@ws:OnClose
When the client connection is closed, this resource will be called.
Example
import ballerina.lang.messages;
@http:BasePath ("/test")
@ws:WebSocketUpgradePath("/websocket")
service helloWorld {
@ws:OnOpen
resource onOpenMessage(message m) {}
@ws:OnTextMessage
resource onTextMessage(message m) {}
@ws:OnClose
resource onCloseMessage(message m) {}
}
Functions of WebSocket
pushing messages to the same client
ws:pusText(text)
This function is used if the user needs to send a text message to the same client who sent the WebSocket message.
| Parameter | Parameter Type | Description | Expected Values |
|---|---|---|---|
| text | string | The text message to send | This can be any string |
For an example, see the simple echo server sample in samples/websocket/echo-server/server/websocketEchoServer.bal
.
Pushing messages to all the clients connected to a given service
ws:broadcastText(text)
This function push text all the clients who have been connected to the currently this function declared service.
| Parameter | Parameter Type | Description | Expected Values |
|---|---|---|---|
| text | string | The text message to send | This can be any string |
Storing and grouping WebSocket connections globally
In Ballerina you can store the WebSocket connections and use them in other services too. There are 2 ways of using this feature. - Storing single connection - Grouping connections
Storing single connection
ws:storeConnection(connectionName)
This function is used to store a given connection globally and it can be retrieved by any other service in Ballerina to push data from server to client.
| Parameter | Parameter Type | Description | Expected Values |
|---|---|---|---|
| connectionName | string | Represent the name of the connection given by the user | A unique string |
note: connection name should be a unique string for a connection. If the same connection name used again, the previous connection will be replaced by the current connection.
ws:pushTextToConnection(connectionName, text)
This function can be used in any service to retrieve a connection which was previously stored by the user and push text to the client.
| Parameter | Parameter Type | Description | Expected Values |
|---|---|---|---|
| connectionName | string | Represent the name of the connection given by the user | A unique string |
| text | string | The text message to send | This can be any string |
ws:removeStoredConnection(connectionName);
This function is used to remove the connection from the global connection store.
| Parameter | Parameter Type | Description | Expected Values |
|---|---|---|---|
| connectionName | string | Represent the name of the connection given by the user | Unique string of the connection |
Grouping WebSocket Connections
ws:addConnectionToGroup(groupName)
This will add the current WebSocket connection to group with the given group name.
| Parameter | Parameter Type | Description | Expected Values |
|---|---|---|---|
| groupName | string | Represent the name of the group which current connection is added | String name represents the group |
ws:pushTextToGroup(groupName, text)
This function can be used globally to access the connection groups defined by any of the services and send text to that specific group.
| Parameter | Parameter Type | Description | Expected Values |
|---|---|---|---|
| groupName | string | Represent the name of the group | String name represents the group |
| text | string | The text message to send | This can be any string |
ws:removeConnectionFromGroup(groupName)
This function removes the current connection from the given group if that connection exists in the given group.
| Parameter | Parameter Type | Description | Expected Values |
|---|---|---|---|
| groupName | string | Represent the name of the group | String name represents the group |
ws:removeConnectionGroup(groupName)
This removes the whole connection group globally. So if the connection group is removed it cannot be used again. But it does not mean that individual connections are removed globally. Because same connection can be added to one or more groups.
| Parameter | Parameter Type | Description | Expected Values |
|---|---|---|---|
| groupName | string | Represent the name of the group | String name represents the group |

If you got this error, please make sure you are using the latest R and ggtree
.
Packages in Bioconductor, like ggtree
, have different release policy compare to CRAN. There are two branches, release and devel, in parallel. Release branch is more stable and only document improvement and bug fixes will commit to it. New functions will only commit to devel
branch.
Sometimes I may write blog post to introduce new functions which is not available in release
branch, you need to install the devel
version of ggtree
in order to use these new functions.
You can download the devel
version of ggtree
from http://bioconductor.org/packages/devel/bioc/html/ggtree.html and install it, or install the github version of ggtree
.
This also applied to other of my packages, including GOSemSim
, DOSE
, clusterProfiler
, ReactomePA
and ChIPseeker
. If you got the could not find function
error, upgrade your installation to latest release. If the error still exists after upgrading to latest release, you need to install the devel version.
ggplot2 can’t auto adjust xlim based on added text.
library(ggtree)
## example tree from https://support.bioconductor.org/p/72398/
tree<-read.tree(text="(Organism1.006G249400.1:0.03977,(Organism2.022118m:0.01337,(Organism3.J34265.1:0.00284,Organism4.G02633.1:0.00468)0.51:0.0104):0.02469);")
ggtree(tree) + geom_tiplab()
This is because the units are in two different spaces (data and pixel). Users can use xlim to allocate more space for tip label.
ggtree(tree) + geom_tiplab() + xlim(0, 0.06)
This could be easily done via the %<+%
operator to attach the
modified version of the labels and than use geom_tiplab
to display
the modified version.
raxml_file <- system.file("extdata/RAxML", "RAxML_bipartitionsBranchLabels.H3", package="ggtree")
raxml <- read.raxml(raxml_file)
lb = get.tree(raxml)$tip.label
d = data.frame(label=lb, label2 = paste("AA", substring(lb, 1, 5)))
ggtree(raxml) %<+% d + geom_tiplab(aes(label=label2))
If you want to format labels, you need to set parse=TRUE
in geom_text
/geom_tiplab
and the label
should be string that can be parsed into expression and displayed as described in ?plotmath
.
For example, the tiplabels contains two parts, species name and accession number and we want to display species name in italic, we can use command like this:
ggtree(rtree(30)) + geom_tiplab(aes(subset=node==35), label='paste(italic("species name"), "accession number")', parse=T)
Another example for formating all tip labels:
ggtree(rtree(30)) + geom_tiplab(aes(label=paste0('bold(', label, ')~italic(', node, ')')), parse=TRUE)
The label
can be provided by a data.frame
that contains related information
of the taxa.
tr <- read.tree(text = "((a,(b,c)),d);")
genus <- c("Gorilla", "Pan", "Homo", "Pongo")
species <- c("gorilla", "spp.", "sapiens", "pygmaeus")
geo <- c("Africa", "Africa", "World", "Asia")
d <- data.frame(label = tr$tip.label, genus = genus,
species = species, geo = geo)
ggtree(tr) %<+% d + xlim(NA, 5) +
geom_tiplab(aes(label=paste0('italic(', genus, ')~bolditalic(', species, ')~', geo)), parse=T)
see also https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/bioc-ggtree/BA7g-npY1BM.
User can use ggrepel package to repel overlapping text labels.
For example:
library(ggrepel)
library(ggtree)
raxml_file <- system.file("extdata/RAxML", "RAxML_bipartitionsBranchLabels.H3", package="ggtree")
raxml <- read.raxml(raxml_file)
ggtree(raxml) + geom_label_repel(aes(label=bootstrap, fill=bootstrap))
For details, please refer to ggrepel usage examples.
It’s quite command to store bootstrap
value as node label in newick
format. Visualizing node label is easy using geom_text2(aes(subset = !isTip, label=label))
.
If you want to only display a subset of bootstrap
(e.g. bootstrap > 80), you can’t simply using geom_text2(subset= (label > 80), label=label)
since label
is a character vector, which contains node label (bootstrap value) and tip label (taxa name). If we use geom_text2(subset=(as.numeric(label) > 80), label=label)
, it will also fail since NAs
were introduced by coercion. We need to convert NAs
to logical FALSE
, this can be done by the following code:
nwk <- system.file("extdata/RAxML","RAxML_bipartitions.H3", package='ggtree')
tr <- read.tree(nwk)
ggtree(tr) + geom_text2(aes(label=label, subset = !is.na(as.numeric(label)) & as.numeric(label) > 80))
Another solution is converting the bootstrap value outside ggtree
as I recommended in google group.
q <- ggtree(tr)
d <- q$data
d <- d[!d$isTip,]
d$label <- as.numeric(d$label)
d <- d[d$label > 80,]
q + geom_text(data=d, aes(label=label))
Here is another exammple for multiple bootstrap support values.
ggtree(rtree(30)) + geom_point()
For example, we can add symbolic points to nodes with geom_point()
directly.
The magic here is we don’t need to map x
and y
position of the points by providing aes(x, y)
to geom_point()
since it was already mapped by ggtree
function and it serves as a global mapping for all layers.
But what if we provide a dataset
in a layer and the dataset
doesn’t contain column of x
and/or y
,
the layer function also try to map x
and y
and also others if you map them in ggtree
function.
As these variable is not available in your dataset
, you will get the following error:
Error in eval(expr, envir, enclos) : object 'x' not found
This can be fixed by using parameter inherit.aes=FALSE
which will disable inheriting mapping from ggtree
function.
$
in aesNEVER DO THIS.
see the explaination in the ggplot2 book 2ed:
Never refer to a variable with
$
(e.g.,diamonds$carat
) inaes()
. This breaks containment, so that the plot no longer contains everything it needs, and causes problems if ggplot2 changes the order of the rows, as it does when facetting.
see my blog post: Edge coloring with user data and also my answer on https://github.com/GuangchuangYu/ggtree/issues/76 and https://groups.google.com/forum/#!topic/bioc-ggtree/4GgivKqVjB8.

Release Notes
Note: prior release notes are appended in reverse order below these notes.
The is the fourth Alpha release of Sets in Motion.
Features Planned
- More calls. Advanced-2 is up next.
Features Added
- The A-1 list has been added to the definitions.
- Call definitions can use two forms of action now: the original single expression
for simple actions, or a new multi-track action for definitions where groups of
two or four dancers at a time are performing distinct moves.
- You can drag tabs from one side of the window to the other to customize the layout
as you like.
- The program will now do calculations of the call results without locking up the
user interface. This makes startup much faster.
- Dance files (such as your Library) will store the last checked status. That
way, if you don't modify the definitions between runs of the program, it doesn't
have to recheck every call every time the program starts.
In the following lists, the letters SD1, SD2,
SD3 denote bugs in square dance choreography while UI1,
UI2, UI3 denote user interface
bugs. The number indicates the severity of the bug. Likelihood of encountering
the bug is not considered in severity. Severity describes how badly the user
is impacted when the bug does occur. The impact criteria for severity settings
are intended to be objective, but borderline cases will always present themselves.
Severity should be interpreted according to the following scale:
- Severity 1 bugs are catastrophic. The user can lose data entirely including
unsaved edits and/or file contents. Data may not be obliterated completely
but may be inaccessible to the user. So, a bug that leaves on-disk data intact,
but causes the program to crash on startup every time would have severity 1.
- Severity 2 bugs are blocking functionality. Data that you have entered is
still present and accessible, but some discrete function does not work correctly
and no work around is possible to achieve the desired function. A display
field that shows incorrect data, for example, would be blocking if the information
was not available anywhere else in the program.
- Severity 3 bugs are non-blocking. Data you have entered is present and accessible.
Some discrete function does not work or some display is misleading, confusing or
malformed. However, any obscured information is available by some other means
and actions you want taken can be done somehow using the program.
Known Bugs
- SD2 Four-dancer stars are not supported in most circumstances..
- SD2 Couples are not defined for infacing rings, where
boy-girl arrangements should be able to do couple-based calls.
- SD2 From a squared set, the call 'turn your partner by
the left 1/2' does not produce a thar. It should.
- SD2 Dancers move through one another without collision.
This is also impossible.
- SD2 Spread does not correctly take into account how the
previous call ended. It should.
- SD2 Do your part does not work correctly if a counter-part
dancer cannot be found when the facing of a phantom is uncertain.
- UI2 Scroll bars in the Definition Editor get misaligned.
Some parts of large, long definitions are inaccessible.
- UI3 The headings in the Dance Editor are misaligned.
- UI3 The Formation Editor will sometimes shift the displayed
position of a formation if new spots are added (this sometimes shifts the spots
completely out of view). Saving and restarting the program fixes the problem.
- UI3 Animations of a weave the ring do not show correct
motions (but do not fail, so the problem is in the partial results).
- UI3 The animation for six-two acy deucey does not work
correctly for four of the dancers. The final position is, however, correct.
Bugs Fixed
- SD2 U-turn back does not properly account for dancer flow.
- UI3 Scroll bars in the Grammar Editor grow much faster
than the size of the window shrinks. Scroll bars get created precisely when
they are needed, but as the window shrinks further, the scroll bar overcompensates
and a large white space develops as you scroll to the bottom.
- UI2 The text displayed for an ampersand is not correct
(essentially the ampersands disappear).
- UI3 The tab heading for a new sequence does not update
when you change the comment.
Alpha-3 Release Notes- July 3, 2010
The is the third Alpha release of Sets in Motion.
Features Planned
- More calls. Advanced is up next.
Features Added
- The Plus list has been added to the definitions.
- The exact version of the product is now displayed in the lower right corner of the
main window of the program.
- A Dancer Designator editor has been added. Now when you expand the Dancer
Designations section of a grammar and click on a dancer designator, a Designator
editor will be brought up in the left-hand sub-window.
- A variety of dancer designations have been added that allow you to more precisely
describe which dancers you want to perform an action. Combinations such as
lead center heads can be typed. You can also specify two
or more groups, as in boys and side girls.
- It is now possible to write formations with Inactive dancers in them (see the
center_box formation and the revised definition for Box Circulate for an example
of how this is used).
- A Performance Window has been added. When you select one or more sequences
you can choose to Perform them, which will open a separate window where you can
read the calls in sequence with a minimum of additional detial to get in the way.
- Preferences have been added to allow you to set the fonts used in the Performance
Window.
- When you create a new Sequence, the editor now automatically puts you on the first
line of the sequence, shows the animation and sets the level to the level of the
last sequence you had in the Sequence Editor. This should allow you to quickly
get started on a new sequence.
- The sequence editor has been enhanced with a new area below the calls where a list
of possible completions of your current typing are shown. These lists update
as you change the sequence level or type in more text.
Known Bugs
- SD2 Four-dancer stars are not supported in most circumstances..
- SD2 Couples are not defined for infacing rings, where
boy-girl arrangements should be able to do couple-based calls.
- SD2 From a squared set, the call 'turn your partner by
the left 1/2' does not produce a thar. It should.
- SD2 Dancers move through one another without collision.
This is also impossible.
- SD2 Spread does not correctly take into account how the
previous call ended. It should.
- SD2 U-turn back does not properly account for dancer flow.
- UI3 Scroll bars in the Grammar Editor grow much faster
than the size of the window shrinks. Scroll bars get created precisely when
they are needed, but as the window shrinks further, the scroll bar overcompensates
and a large white space develops as you scroll to the bottom.
- UI2 Scroll bars in the Definition Editor get misaligned.
Some parts of large, long definitions are inaccessible.
- UI3 The tab heading for a new sequence does not update
when you change the comment.
- UI3 The headings in the Dance Editor are misaligned.
- UI2 The text displayed for an ampersand is not correct
(essentially the ampersands disappear).
- UI3 The Formation Editor will sometimes shift the displayed
position of a formation if new spots are added (this sometimes shifts the spots
completely out of view). Saving and restarting the program fixes the problem.
Bugs Fixed
- SD2 Limited four-dancer stars are now supported.
Dancers in twin diamonds can be switched to four-dancer
stars which can then be turned. Twin four-dancer stars can subsequently be
restored to diamonds.
- SD2 Two-ladies chain 3/4 now works.
- SD2 The Same Position Rule was not working correctly.
Calls that made dancers collide would fail with "Motions are not valid".
- SD2 From a quarter tag, calling "centers cast off 3/4'
should yield a proper 2x4 arrangement. It does now.
- UI1 The program could run out of fonts, but in practice
this would require substantial amounts of usage (opening and closing lots of windows,
printing lots of pages, etc.).
- UI1 Under some conditions when you have opened a call
in the Call Analysis browser, the program will crash when you modify a definition
(which should flush the analysis pages).
Alpha-2 Release Notes- June 3, 2010
This is the second Alpha release of Sets in Motion.
Features Planned
- Some form of 'smart' editing of sequences. Think of it as 'auto-complete'
or 'intellisense' for calls. This is a priority to develop.
- More designations. This release reworked the parsing of ANYONE phrases so
that 'beaus' and 'belles' now are marked as A-1 terms. These changes also
made it much easier to add new phrases. For this release, for example, the
following new phrases are now recognized:
- lead ANYONE - designates dancers who are leaders as well as the
following ANYONE phrase. For example: 'lead girls', 'lead ends'.
- end ANYONE - designates dancers who are ends in the current formation
as well as the following ANYONE phrase. For example: 'end boys', 'end heads'.
- center ANYONE - designates dancers who are centers in the current
formation as well as the following ANYONE phrase. For example: 'center beaus'.
Obviously, many more such phrases need to be added. - More calls. The Plus level is up next.
Features Added
- The Mainstream list has been added to the definitions.
- A Formation Editor has been added. Now when you expand the Formations section
of a grammar and click on a formation name, a Formation Editor will be brought up
in the right-hand sub-window.
- Formation diagrams have been added to the definitions. Each valid formation
pattern will include the formation to its right.
- There is now a button to delete a part of a definition variant.
- Buttons have been added to variants to move them up or down within the definition.
- Preferences have been added to give you control of the layout of a printed sequence.
You can set the various margins and fonts on the preferences page now and they will
apply to the next printing (and will be retained until you change them again).
Known Bugs
- Four-dancer stars are not supported.
- Two ladies chain 3/4 cannot be expressed.
- Couples are not defined for infacing rings, when boy-girl arrangements should be
able to do couple-based calls.
- From a squared set, the call 'turn your partner by the left 1/2' does not produce
a thar. It should.
- From a quarter tag, calling "centers cast off 3/4' does not yield a proper 2x4 arrangement.
It should.
- Dancers move through one another without collision. This is also impossible.
Bugs Fixed
- Scrollbars did not work properly if the section was too small. Essentially
clicking on the scrollbars would be interpreted as clicking on the enclosed window
instead.
- Editing sequences could end up causing your typing to double, triple or even more,
sssooo aaa ppphhhrrraaassseee lllooooookkkeeeddd llliiikkkeee ttthhhiiisss.
- Typos or otherwise malformed calls entered in the Sequence Editor could crash the
program. This was somewhat unpredictable. Error recovery when parsing
is now handled correctly.
- If you edited a long definition that required scrolling, the scroll bars would reset
after each change. They are preserved now.
- Column circulates did not work. All dancers always stepped forward, even the
leads of the columns.
- The call 'ends circulate' for parallel lines did not work. It has been added.
- The call 'promenade home' from left-hand two-faced lines was not recognized.
It has been added.
- Fractionalizing some calls was not working. This included things like 'split
circulate 1 and 1/2'.
- You can now close and re-open dance files as many times as you like.
- You can now place empty lines in a sequence without interfering with the animation.
- Beaus and belles are now restricted to A-1 and above.
- A number of situations caused the generated motions of the dancers to be incorrect.
At least eight different bugs fell into this category and a detailed explanation
of all of them is not worth the space. At this point, all known issues with
calls succeeding, but producing dis-continuous motion are fixed.
Alpha-1 Release Notes- May 16, 2010
This is the first public release of Sets in Motion. Using a relatively
standard terminology, this is an Alpha-quality release. This means that some
key features (like formation viewing/editing) are missing, and other functions (printer
formatting) are incomplete. The program has been tested, so most features
that are documented are available and will likely work correctly. Calls may
have significant bugs in their definitions. In particular, the starting formation
may be incomplete or the existing definition language may not work correctly for
some starting formations.
As soon as I deliver this version, I will begin working on the next, more mature
release. I plan on releasing several updates before calling this an officially
released product. Until then, expect to see occasional new updates.
I will be setting up a Web-site to make checking for and getting updates possible.
For now, this package is being distributed via e-mail to specific individuals.
Feedback Needed
I am interested in getting broad feedback on how the major components of the user
interface flow together. Does it make sense to you when shifting from editing
a sequence to using the animation or call analyzer. Are the labels on buttons
clear? Are there key features that you need that do not appear in the program.
I have my own ideas about the future direction of the program and have hinted at
future features in places. I do not want to bias you, however, so I have refrained
from much prognostication. I really want to know what you think would be useful
(hopefully to most users).
Is the help text accurate and useful? Do I need more detailed discussion of
the program controls and displays? Are the essays in the Caller's Guide helpful
or confusing? What topics would you have liked to see, but are missing?
Most importantly, try composing some sequences. So far, the Basic list is
pretty completely implemented. I don't expect you to write much material but
anything you could do to identify wrong or missing call variations will be very
useful.
At this stage, the definitions and primitives are not thoroughly documented, so
I would be amazed if you could figure out how to do more than minor tweeks.
The definition language is pretty unexpressive currently, so many more advanced
concepts are simply impossible to express.
If you have any feedback or questions, e-mail me at<EMAIL_ADDRESS>Please check the following list of known issues before reporting anything.
When in doubt, report a problem. In particular, none of the known issues cause
the program to crash or lock up indefinitely. The program should be responsive
no matter what. If you see any of these severe failures, please let me know
about it.
The program should not corrupt your data. Definitely let me know if you think
you have saved something and it does not reload properly. If your machine
crashes while the program is writing data, I can't make any guarantees. In
general, the program will create a backup copy of any file before it tries to save
a new copy, but there is no automated way to recover these backups. If you
think you have a corrupted file, do not save again. That will destroy the
backup. Contact me if you need help finding and restoring the backup files.
Known Bugs
- Four-dancer stars are not supported.
- Two ladies chain 3/4 cannot be expressed.
- Beaus and belles are not restricted to Advanced and above.
- Closing a dance-file editor and re-opening it does not work correctly. The
file is locked out until you restart the program. (You can close and re-open
the My Library, Definitions and My Definitions files correctly.)
- If you have a blank line in a sequence, the animation playback will 'get stuck'
at the blank. You will see the timer move forward and eventually stop, but
the dancers freeze at the position of the blank line and then instantaneously jump
to the final position when the animation completes.

If men, in their researches into the history of this country, in noticing the mounds, fortifications, statues, architecture, implements of war, of husbandry, and ornaments of silver, brass, etc.-were to examine the XXBOOKOFMORMON, their conjectures would be removed, and their opinions altered; uncertainty and doubt would be changed into certainty and facts; and they would find that those things that they are anxiously prying into were matters of history, unfolded in that book. They would find their conjectures were more than realized-that a great and a mighty people had inhabited this continent-that the arts sciences and religion, had prevailed to a very great extent, and that there was as great and mighty cities on this continent as on the continent of Asia. Babylon, Ninevah, nor any of the ruins of the Levant could boast of more perfect sculpture, better architectural designs, and more imperishable ruins, than what are found on this continent. Stephens and Catherwood's researches in Central America abundantly testify of this thing. The stupendous ruins, the elegant sculpture, and the magnificence of the ruins of Guatemala, and other cities, corroborate this statement, and show that a great and mighty people-men of great minds, clear intellect, bright genius, and comprehensive designs inhabited this continent.


Kosovo 0-4 England: player ratings from the Euro 2020 qualifier
by Ben FisherBen Chilwell and Harry Kane were impressive for England, while Fidan Aliti struggled for Kosovo
Kosovo (4-3-3)
Arijanet Muric The Manchester City goalkeeper repelled effort by clubmate Sterling but had no chance with goals. 7
Mergim Vojvoda Showed some neat touches on the ball and gave Kosovo a presence in both halves. 6
Amir Rrahmani The no-nonsense captain squandered a free header moments after glancing Berisha’s effort wide. 6
Fidan Aliti Went missing for opener and his sliced clearance fell to Kane for England’s second. 5
Benjamin Kololli His rampaging runs provided a threat down the left . Booked for manhandling Sterling. 7
Bersant Celina The Swansea winger operated centrally and provided a touch of class. Spurned inviting chance. 7
Ibrahim Dresevic Went to sleep as Winks waltzed through on goal unchallenged. Late slip allowed Mount to strike. 4
Valon Berisha Seemed to hold the upper hand against a youthful and, at times, green England midfield. 7
Florent Hadergjonaj The high-energy Huddersfield defender made a dent on the right wing but faded. 6
Atdhe Nuhiu Burly Sheffield Wednesday striker relished leading the line in the absence of Vedat Muriqi. 6
Milot Rashica Was lively down the left, testing Pope from distance and got the better of Alexander-Arnold. 7
Subs Besar Halimi (for Berisha 65) 7, Edon Zhegrova (for Hadergjonaj 73) 6, Elba Rashani (for Nuhiu 82) 6
England (4-3-3)
Nick Pope Largely untroubled on full England debut but among those guilty of getting sloppy. 6
Trent Alexander-Arnold An off night. Occasionally exposed and failed to torment opposition defence going forward. 5
Harry Maguire Did not do a lot wrong but at the heart of a defence that struggled to convince. 6
Tyrone Mings Not at his imposing best. Had hands full with Nuhiu, who ensured a heavyweight battle. 5
Ben Chilwell Another fine performance. His gallivanting down the left was a catalyst for England throughout. 7
Alex Oxlade-Chamberlain Slipped in Winks for opener. Has been involved in six goals in past seven games. 6
Declan Rice Another who grew into the game. Made a crucial block to deny Rashica late on. 6
Harry Winks Failed to assert himself until bursting into the box and coolly slotting home his first England goal. 6
Raheem Sterling A low-key return. Wonderfully weighted pass supplied Rashford for England’s third. 6
Harry Kane Quiet until rattling a post on the hour mark. Slammed home second to maintain scoring streak. 7
Callum Hudson-Odoi The teenager struggled on his second start. Too often his final pass disappointed. 5
Subs Marcus Rashford (for Hudson-Odoi 59) 7, Mason Mount (for Oxlade-Chamberlain 72) 6, Fikayo Tomori (for Alexander-Arnold 84) 6

In this process, unit tests are written first, by the software engineers (often with pair programming in the extreme programming methodology). Of course these tests fail initially; as they are expected to. Then as code is written it passes incrementally larger portions of the test suites. The test suites are continuously updated as new failure conditions and corner cases are discovered, and they are integrated with any regression tests that are developed. Unit tests are maintained along with the rest of the software source code and generally integrated into the build process (with inherently interactive tests being relegated to a partially manual build acceptance process). The ultimate goal of this test process is to achieve continuous integration where software updates can be published to the public frequently. ---
I'm very happy to be a guest speaker at QCon Beijing in April 2012.
I submitted the 2 abstracts below. We haven't agreed completely on the schedule, but it seems like one of them will be a half-day tutorial (Shallow Depth of Tests) and the other one a talk (Predictably and Irrationally Agile).
Shallow Depth of Tests - Scalable TDD/BDD
Test automation is prevalent in the software development community. Practices like TDD and BDD are widespread and applied almost unquestionably. However, several organisations have struggled in attempting to scale automated test suites, which very often become slow, brittle, non-deterministic, unreliable and difficult to maintain.
In this talk, I will discuss some common mistakes, Tautological TDD (TTDD), for example, and also present patterns that I have successfully applied, such as Shallow Depth of Tests and Testing Pyramid. These have enabled us to achieve maintainable and scalable tests that fulfill their purpose - to help software development teams deliver faster and more confidently the features required by business people.
Predictably and Irrationally Agile
People behavior is one of the centerpieces of Agile software development. Cognitive Psychology and Behavioral Economics have helped us achieve a better understanding of some human seemingly idiosyncratic behaviors, for example, the decoy effect on the decision-making process. Agile teams are constantly making decisions, for instance, while prioritising, estimating stories or choosing the size of an iteration.
This talk will compare and correlate Dan Ariely's controlled experiments described in his book "Predictably Irrational" to Agile. The anticipated result should be an increased awareness of the reasoning behind some Agile values, principles and practices which, as a consequence, should improve the way we apply them as agile adopters and practitioners.

Indiegogo explains entrepreneurial focus
by Yanitsa BoyadzhievaINTERVIEW: Indiegogo CEO Andy Yang (pictured) explained the company developed a feature to enable entrepreneurs to continuously raise capital, as the crowdfunding platform moves to expand its offerings.
The executive outlined its InDemand feature as a key difference between the company and its competitors, as it “helps entrepreneurs fund beyond their initial campaign”, enabling them to stick with the platform “and continue to raise capital”.
“We have this entrepreneur community and this backer consumer community, and we are trying to connect them through conversation and different campaigns”.
Since the start of his tenure in May, Yang said he has seen a rise in the number of repeat entrepreneurs and campaigners using the platform. This is currently concentrated on North America, which comprises about a third of the company’s business.
Yang also discussed some of the most notable projects in the mobile tech sector which are supported by the platform, along with its participation in the 4 Years From Now event at MWC19 Los Angeles.

What is enumeration about?
Typical Question: How many elements of a given set S have a given property?
We’ll answer such questions by encoding the properties of S using an algebraic expression called the generating series for S.
Then to answer the question, we will find a certain coefficient in the generating series.
eg: How many ways can you choose a dozen doughnuts if the available flavours are: Chocolate, Maple, Lemon, and Plain (at least 12 of each are available)?
The generating series for this problem is
The answer is the coefficient of in which we denote by
eg: Same question but now only 3 chocolate, and 5 maple are available (other 2 have > 12 still).
The generating series becomes
The answer is
eg: In the doughnut shop there are 3 chocolate, 5 maple, 19 lemon and 17 plain doughnuts left. Describe the set of all collections of doughnuts that can be formed (size of the collection not specified) as a Cartesian product.
Answer: as CP is : (chocolate) {0, 1, 2, 3} x (maple) {0, 1, 2, 3, 4, 5} x (lemon) {0, 1, … , 19} x (plain) {0, 1 , … , 17}eg: No box contains BOTH chocolate and maple this time
Answer: as CP is :
= {0, 1, 2, 3} x {0} x {0, 1, … , 19} x {0, 1 , … , 17} {0} x {1, 2, 3, 4, 5} x {0, 1, … , 19} x {0, 1 , … , 17}Let m be a positive integer
eg: Let S be the set of all subsets of {1, 7, … , m}. Fix k.
How many elements of S have size k?
ie. How many k-subsets (subsets of size k) of {1, … , m} are there?
Theorem: the number of k-subsets of {1, … , m} is
Proof: Let (B is binomial) B(m,k) denote he number of k-subsets of {1, … , m}
Consider the set of ordered k-tuples of distinct elements of {1, … , m}
Then
Now count as follows: make a list of all B(m, k) k-subsets of {1, … , m} and then order each subset in all k! possible ways.
So
Hence,
So,
Recall that for a fps (formal power series) A(x) we denote by the coefficient of in .
Substitution: Let A(x) = and be fps. Suppose that the constant coefficient of B(x) is 0. Then A(B(x)) is a fps.
Proof:
Since we can write where
Then
To show this a fps, we need to show that for every 0, is a finite rational number. The good thing is: and is a fps since it is a finite sum of finite products of fps, which is a fps .
What goes wrong when ?
We get
Then for example which is NOT in general a finite rational number. So in general, A(B(x)) is not a fps.
Inverse: Let A(x) be a fps. We say the fps C(x) is the (multiplicative) inverse of A(x) if
e.g.:
has inverse
Note: Multiplication of fps is symmetric therefore we can write We write
Check:
Thm: The fps A(x) has an inverse if and only if is non-zero
Proof: (=>) suppose C(x) is the inverse of A(x)
Then
Therefore
{<=} Supposed . Then we can write where
we claim is a fps: note that it is xB(x) substituted into and xB(x) has constant coefficient 0. Thus C(x) is a fps.
Then
So by definition
eg. The inverse of is
Then
It is usually more convenient to express this as
Note that if A(x) has an inverse, then it is unique: Since if A(x)B(x) = 1 and A(x)C(x) =1. Then C(x)A(x)B(x) = C(x) => B(x) = C(x)
Note that if A(x) has an inverse and B(x) has an inverse then A(x)B(x) has inverse
eg. How many

Always Start with Layer 1
Anyone who has worked with hardware, particularly in the networking world, is probably familiar with this phrase. It seems fitting that this topic would be first for my blog considering it's step 1 most of the time.
For those not familiar with this phrase, let me introduce you to the OSI 7 Layer Model. The gist of the model is that most technology related communication, particularly networking, can be broken down into 7 layers. The first layer is physical
which refers to the literal physical components that make up the communication infrastructure. Basically it's the cables, switches, NICs, etc that are part of your network.
Have you ever spent time working on an issue for hours only to find that it was just a bad cable? That's exactly a time when you should have checked Layer 1 first.
I work remotely for a regional telecom in the Great Lakes area. Often I'm at coffee shops with throttled wifi or other places with flaky connections that make my work difficult. Thankfully, I still have a grandfathered unlimited data plan through Verizon with tethering. (Okay, I don't actually pay for tethering but the FCC says I should be able to use my data the way I want, right?)
My phone has been super reliable most of the time but in the past 2 weeks I started to notice that I was often dropping the connection. It seemed to be worse in coffee shops opposed to when I was sitting at my own table at home. My tablet (a Dell Venue 11 Pro) has absolutely no problems and works perfectly.
Tonight I was at a coffee shop and I was having the same problem again. Rather than deal with it this time I decided to roll my sleeves up and dig in. Looking through the system logs (via journalctl -f
, I run Arch Linux) I noticed intermittent authentication issues.
If you're not familiar with WPA2
(a wifi security protocol), it has a rekey interval to keep nasty hackers from getting into your connection. The theory is that if you rekey often enough in the off chance someone does crack your hash it'll be too late since you'll be on a new one by then (heavily paraphrased). It was during these rekeying operations that my laptop wouldn't always rekey properly and would drop the connection. Sometimes it would even ask for the PSK (password) again.
There were plenty of results to sort through when Googling wpa_supplicant reason=4 ath9k
including some suggestions to drop back to an older version of wpa_supplicant. Nothing seemed to solve the problem and I was on the verge of buying a new mini PCIe wireless card for my laptop (a Dell Precision M4800). During all of my testing I had a simple ping <IP_ADDRESS>
(a Google DNS server) running to see if traffic was flowing.
Just then I received a text from a friend and picked up my phone. As soon as I did all of my pings started to get replies. Thinking it was a coincidence I set my phone back down and the replies stopped. I picked up my phone again and everything started working.
 That 2 week timeframe I mentioned before? I bought a new USB cable 2 weeks ago that was only 8 inches so I could have my phone plugged into my laptop while it was tethered without having 4 extra feet of cord hanging around. With the shorter core I started placing my phone on the left of my laptop (instead or wrapping it around the back) so it wasn't in the way of my mouse.
I'm once again reminded of how Layer 1 can be so tricky to find because they're so simple. Although the cable itself isn't to blame it does highlight how even the smallest changes can cause unintended consequences. Remember- always start with layer 1.


Week 15 Fantasy PPR Rankings: Tight end
by Billy HeyenWhat a disappointing week it was for two of the tight ends we considered to have such good matchups that they weren't even sleepers: Jack Doyle and Vance McDonald. Our Week 15 TEPPR rankings suggest there's still value with Doyle, but McDonald can return to the free agent scrap heap. David Njoku seems like a surefireplay this week, but maybe we should look at McDonald as a warning for mediocre TEs in highly favorable matchups.
Njoku is facing the same fantasy-friendly Cardinals defense thatMcDonald did. However, the beliefe is that Njoku is much more talented, despite only playing in three games this year and doing next to nothing in his return from a wrist injury in Week 14. We still like him as the top tight end pickup this week if he's available in your league, but obviously there's some risk.
WEEK 15 NON-PPR RANKINGS:
Quarterback | Running back | Wide receiver | Tight end | D/ST | Kicker
If you don't have one of the top tight ends this week, you're probably worrying about TE injuries. Gerald Everett (knee), Greg Olsen (concussion), Evan Engram (foot),Ryan Griffin (ankle), Mark Andrews (knee/thigh), Noah Fant (foot), and Jared Cook (cook) are all hurt. Three of their backups would be worth considering as replacements: Carolina's Ian Thomas, the Giants' Kaden Smith, and Baltimore's Hayden Hurst. If you have any of those seven (or McDonald), it's worth checking on those three along with Njoku on the waiver wire.
WEEK 15 PPR RANKINGS: Running back | Wide receiver
Other than that, it's a pretty usual week in tight end land. Austin Hooper would raise the most concern heading into a matchup with the 49ers, but Hooper's target share (six) in Week 14 suggests he's healthy enough to make an impact down the stretch (and if the Falcons are without Calvin Ridley, Hooper will be more important). There's an argument to be made to streaming someone like Njoku over Hooper, but there's also plenty of argument to sticking with your stud and not kicking yourself for going away from him.
One last thing before you get to the rankings: Tyler Higbee looks like more than just a beneficiary of an Arizona matchup in Week 13. He surpassed 100 yards again, this time against the Seahawks on Sunday night. He'll put up good numbers if he gets a similar opportunity when the Rams travel to Dallas for Week 15.
Reminder: Check back for updatesduring the week.For more individual tight end analysis, click here.

Military lockdown continues on 100th consecutive day in IoK
by https://www.facebook.com/dunyanewsSRINAGAR (Web Desk) - In occupied Kashmir, military lockdown and restrictions continue on 100th consecutive day today (Tuesday) in Kashmir valley and Muslim majority areas of Jammu and Ladakh following the August 5 Indian illegal decision to abrogate special status of occupied Kashmir.
According to Kashmir Media Service, restrictions under Section 144 and ban on prepaid phone, SMS and internet services remain enforced.
As a mark of silent protest, people in the Valley continue to keep their shops closed except for a brief period in the morning and evening and stay away from schools and offices.
Public transport is also unavailable in the occupied valley.

Note that there is no requirement that the Hudson master server is running as a Windows service in order to run agents as a Windows service. For more information on how to set up just an agent go to #Hudson agent service
Hudson master server
Running Hudson master server as a windows service can be done in several ways, either through the servlet containers or using the Winstone container. This section describes how to run Hudson master server using the Winstone container.
To run the Hudson master server as a windows service using Winstone the Java Service Wrapper can be used to integrate Hudson as a Windows service. The below parts will get you up and running with Hudson as a Windows service but for more information please see the JSW site.
Installation
- Download the latest Hudson.war file. IE users: Make sure that the file is downloaded as a .war file.
- Download the Hudson Windows Service package from this page. The package uses Wrapper 3.2.3
- Unzip the Hudson package into an empty folder. You should now have the following layout:
Hudson +- bin | +- Hudson.bat | +- InstallHudson.bat | +- UninstallHudson.bat | +- wrapper.exe +- conf | +- wrapper.conf +- lib | +- wrapper.jar | +- wrapper.dll
- Copy the
Hudson.war
to thelib
folder - Now the file layout is setup so Hudson can be installed as a service.
Configuration
The JSW reads from the conf/wrapper.conf
and is ready to be used. The default home path for Hudson is data
, and if you want to change that you need to edit the configuration.
If you don't have a java.exe on your PATH, change the wrapper.java.command in conf/wrapper.conf from just "java" to e.g. wrapper.java.command=C:/jdk1.6.0_03/bin/java.
Below is a condensed version of the configuration file for the Hudson options, the conf/wrapper.conf
will also contain options for the Wrapper library.
# Change below line to change the Hudson home path wrapper.java.additional.1=-DHUDSON_HOME=../data
Service handling
- To install the service run
bin/InstallHudson.bat
- To uninstall the service run
bin/UninstallHudson.bat
- To start the service run
net start hudson
- To stop the service run
net stop hudson
Frequently asked questions
Troubleshooting / Logs
If the service doesn't start, have a look at the wrapper.log
which will be created in the bin
directory when the service attempts to start.
I want to run on a different port than default 8080.
Open up the conf/wrapper.conf
and add the following line.
wrapper.app.parameter.2=--httpPort=8090
When I try to run the application I get wrapper | OpenSCManager failed - Access denied
?
This is because you don't have the necessary permissions, please ask an administrator to install the service.
How can I run the service as a specified user?
Open up the conf/wrapper.conf
and change the following properties
wrapper.ntservice.account = accountname wrapper.ntservice.password = password
Why doesnt the Hudson server start in Windows 64bit?
Unfortunately the JSW does not support 64 bits Windows (as of now, 4th november 2007). You can install a 32bits version of Java and specify the Java in the conf/wrapper.conf
.
wrapper.java.command=c:\program files(x86)\java\bin\java.exe
Hudson agent service
To install the Hudson agents as a windows service the Java Service Wrapper can be used for integrating with Windows and Netx for starting the agent using the Hudson JNLP application. It is almost as simple installing the Hudson master server, but there is one extra configuration step for each agent machine.
Installation
- Download the Hudson Agent package from this page. The package uses Wrapper 3.2.3, and Netx 0.5.0.
- Unzip the Hudson package into an empty folder. You should now have the following layout:
Hudson +- bin | +- HudsonAgent.bat | +- InstallHudsonAgent.bat | +- UninstallHudsonAgent.bat | +- wrapper.exe +- cache (Web start cache needed by Netx) +- conf | +- wrapper.conf +- lib | +- wrapper.jar | +- wrapper.dll | +- netx-no-debug.jar
Configuration
The JSW reads from the conf/wrapper.conf
which must be updated before service is started. When installing the above packages on each agent, you must specify the JNLP file that should be started in the service. The JNLP file is unique for each agent, and the link can be found in the agent machine page.
- Show the Hudson main page
- Click on the agent link under the build queue
- Copy the Web start link from the agent page
- Update the
wrapper.app.parameter.7
with the link in theconf/wrapper.conf
.
Below is a condensed version of the configuration file for the Hudson options, the conf/wrapper.conf
will also contain options for the Wrapper library.
# Application parameters. Add parameters as needed starting from 1 wrapper.app.parameter.1=netx.jnlp.runtime.Boot wrapper.app.parameter.2=-headless wrapper.app.parameter.3=-basedir wrapper.app.parameter.4=../cache wrapper.app.parameter.5=-nosecurity wrapper.app.parameter.6=-jnlp wrapper.app.parameter.7=http://akira:8090/computer/WS-1/slave-agent.jnlp
Service handling
- To install the service run
bin/InstallHudsonAgent.bat
- To uninstall the service run
bin/UninstallHudsonAgent.bat
- To start the service run
net start hudson-agent
- To start the service run
net stop hudson-agent
Frequently asked questions
The master server has been updated, how do I update all agents?
Stopping and starting the services will initiate a download of the new JNLP agent application.
Other Service Options
FireDaemon Lite V1.6

Sometimes some MEG or EEG channels are not functioning properly for various reasons. These channels should be excluded from analysis by marking them bad as. This is done by setting the ‘bads’ in the measurement info of a data container object (e.g. Raw, Epochs, Evoked). The info[‘bads’] value is a Python string. Here is example:
raw.info['bads'] = ['MEG 2443']
Why setting a channel bad?: If a channel does not show a signal at all (flat) it is important to exclude it from the analysis. If a channel as a noise level significantly higher than the other channels it should be marked as bad. Presence of bad channels can have terribe consequences on down stream analysis. For a flat channel some noise estimate will be unrealistically low and thus the current estimate calculations will give a strong weight to the zero signal on the flat channels and will essentially vanish. Noisy channels can also affect others when signal-space projections or EEG average electrode reference is employed. Noisy bad channels can also adversely affect averaging and noise-covariance matrix estimation by causing unnecessary rejections of epochs.
Recommended ways to identify bad channels are:
mne.io.Raw.plot()
without SSP/ICA
enabled and identify bad channels.Note
Setting the bad channels should be done as early as possible in the analysis pipeline. That’s why it’s recommended to set bad channels the raw objects/files. If present in the raw data files, the bad channel selections will be automatically transferred to averaged files, noise-covariance matrices, forward solution files, and inverse operator decompositions.
The actual removal happens using pick_types
with
exclude=’bads’ option (see Obtaining subsets of channels).
Instead of removing the bad channels, you can also try to repair them. This is done by interpolation of the data from other channels. To illustrate how to use channel interpolation let us load some data.
# Reading data with a bad channel marked as bad:
fname = data_path + '/MEG/sample/sample_audvis-ave.fif'
evoked = mne.read_evokeds(fname, condition='Left Auditory',
baseline=(None, 0))
# restrict the evoked to EEG and MEG channels
evoked.pick_types(meg=True, eeg=True, exclude=[])
# plot with bads
evoked.plot(exclude=[])
print(evoked.info['bads'])

Note
Interpolation is a linear operation that can be performed also on Raw and Epochs objects.
For more details on interpolation see the page Repairing bad channels.
MNE provides an mne.Annotations
class that can be used to mark
segments of raw data and to reject epochs that overlap with bad segments
of data. The annotations are automatically synchronized with raw data as
long as the timestamps of raw data and annotations are in sync.
See Brainstorm auditory tutorial dataset for a long example exploiting the annotations for artifact removal.
The instances of annotations are created by providing a list of onsets and
offsets with descriptions for each segment. The onsets and offsets are marked
as seconds. onset
refers to time from start of the data. offset
is
the duration of the annotation. The instance of mne.Annotations
can be added as an attribute of mne.io.Raw
.
eog_events = mne.preprocessing.find_eog_events(raw)
n_blinks = len(eog_events)
# Center to cover the whole blink with full duration of 0.5s:
onset = eog_events[:, 0] / raw.info['sfreq'] - 0.25
duration = np.repeat(0.5, n_blinks)
raw.annotations = mne.Annotations(onset, duration, ['bad blink'] * n_blinks)
raw.plot(events=eog_events) # To see the annotated segments.
Out:
EOG channel index for this subject is: [375]
Filtering the data to remove DC offset to help distinguish blinks from saccades
Now detecting blinks and generating corresponding events
Number of EOG events detected : 46
As the data is epoched, all the epochs overlapping with segments whose
description starts with ‘bad’ are rejected by default. To turn rejection off,
use keyword argument reject_by_annotation=False
when constructing
mne.Epochs
. When working with neuromag data, the first_samp
offset of raw acquisition is also taken into account the same way as with
event lists. For more see mne.Epochs
and mne.Annotations
.
When working with segmented data (Epochs) MNE offers a quite simple approach to automatically reject/ignore bad epochs. This is done by defining thresholds for peak-to-peak amplitude and flat signal detection.
In the following code we build Epochs from Raw object. One of the provided parameter is named reject. It is a dictionary where every key is a channel type as a sring and the corresponding values are peak-to-peak rejection parameters (amplitude ranges as floats). Below we define the peak-to-peak rejection values for gradiometers, magnetometers and EOG:
reject = dict(grad=4000e-13, mag=4e-12, eog=150e-6)
Note
The rejection values can be highly data dependent. You should be careful when adjusting these values. Make sure not too many epochs are rejected and look into the cause of the rejections. Maybe it’s just a matter of marking a single channel as bad and you’ll be able to save a lot of data.
We then construct the epochs
events = mne.find_events(raw, stim_channel='STI 014')
event_id = {"auditory/left": 1}
tmin = -0.2 # start of each epoch (200ms before the trigger)
tmax = 0.5 # end of each epoch (500ms after the trigger)
baseline = (None, 0) # means from the first instant to t = 0
picks_meg = mne.pick_types(raw.info, meg=True, eeg=False, eog=True,
stim=False, exclude='bads')
epochs = mne.Epochs(raw, events, event_id, tmin, tmax, proj=True,
picks=picks_meg, baseline=baseline, reject=reject,
reject_by_annotation=True)
Out:
319 events found
Events id: [ 1 2 3 4 5 32]
72 matching events found
Applying baseline correction (mode: mean)
Created an SSP operator (subspace dimension = 3)
4 projection items activated
We then drop/reject the bad epochs
epochs.drop_bad()
Out:
Loading data for 72 events and 106 original time points ...
Rejecting epoch based on EOG : [u'EOG 061']
Rejecting epoch based on MAG : [u'MEG 1711']
22 bad epochs dropped
And plot the so-called drop log that details the reason for which some epochs have been dropped.
print(epochs.drop_log[40:45]) # only a subset
epochs.plot_drop_log()
Out:
[['bad blink'], ['IGNORED'], ['IGNORED'], ['IGNORED'], ['bad blink']]
What you see is that some drop log values are empty. It means event was kept. If it says ‘IGNORED’ is means the event_id did not contain the associated event. If it gives the name of channel such as ‘EOG 061’ it means the epoch was rejected because ‘EOG 061’ exceeded the peak-to-peak rejection limit.
Total running time of the script: (0 minutes 10.633 seconds)

Boilerplate is any text that is or can be reused in new contexts or applications without being greatly changed from the original.
In the field of printing, the term dates back to the early 1900s. From the 1890s onwards, printing plates of text for widespread reproduction such as advertisements or syndicated columns were cast or stamped in steel (instead of the much softer and less durable lead alloys used otherwise) ready for the printing press and distributed to newspapers around the United States. By analogy, they came to be known as 'boilerplates'. One large supplier to newspapers of this kind of boilerplate was the Western Newspaper Union, which supplied "ready-to-print stories [which] contained national or international news" to papers with smaller geographic footprints, which could include advertisements pre-printed next to the conventional content.[2]
Some companies also sent out press releases as boilerplate so that they had to be printed as written. The modern equivalent is the press release boilerplate, or "boiler," a paragraph or two that describes the company and its products.
Boilerplate language may also exist in pre-created form letters on the Internet for such things as issues to be broached by a politician based on an issue ad, requests that a cable or satellite operator add a cable network to a system, pre-written complaints about a product that is opposed by groups that create such letters, or online petitions. The person requesting the action usually only needs to type or sign his or her name at the end of the pre-written greeting and body.
In computer programming, boilerplate is the sections of code that have to be included in many places with little or no alteration. Such boilerplate is particularly salient when the programmer must include a lot of code for minimal functionality. The need for boilerplate can be reduced through high-level mechanisms.
A related phenomenon, bookkeeping code, is code that is not part of the business logic but is interleaved with it in order to keep data structures updated or able to handle secondary aspects of the program.

Welcome to APN Assistant.
This projects grown your & my app, APN Assistant.
Why start this?
Sometimes, Apple hide APN setting from iOS devices.
Why? In my opinion, Apple preferential treatment relationship to Major Mobile Operators, not Users!
Almost cases, iPhone & iPad is so smart. Like case of choose major mobile operator, users have no problems.
Case of choose minor mobile operator(like MVNO), users have to set APN manually, because Apple don't show APN setting for us.
This specification is bad, especially change SIM while traveling.
Because installation of config profile need Internet, almost case using free Wi-Fi network.
But, we can not all find free Wi-Fi while traveling.
I thought this is good opportunity for me to create good convenient app and sale on App Store.
But this app rejected from Apple.
So, I'll release source code to Open Source.
You can use this app if you have a Apple Developer Program License.
Sales on App Store
But, App Store Review is inconsistent. It means we still have chanse to provide apps on App Store.
So, you can install theres from App Store yet, Please check out and buy if this app become to your favorites.
Or, you can use this app on Web.

*This was orginally posted to the usenet newsgroup alt.drugs.psychedelics*
You may have noticed my post titled 'DXM Virgin' where my mate wanted to take DXM to go to a concert. I managed to dissuade him and we took E instead. I took 2.5 tabs, 1.5 more than I normally would, simply cos he was (yeah I am too easily persuaded).
So anyway he came over on Saturday night and we got some wine and smoked some weed. The next day I woke up feeling a little the worse for wear, but not too bad. My friend came down again and we smoked another 3 or 4 joints before he had the idea to take some dex. I didn't think this was a good idea as it was Sunday evening and I had work the next day, and from what I had read on the FAQ this wasn't your typical drug. BTW I have never taken it before.
But stupidly I was talked into taking some. I had some in powdered form, so measuring it was pretty hard. All we did was measure what looked like a quarter of a gram (250mg) put it in a skin and swallow it. This was at 5:30pm on Sunday.
After about an hour nothing much was happening so (fucking idiots) we decided to repeat this again. About an hour later I started to feel really strange and felt as though I was sinking into the couch. I didn't feel like talking much and for a while I didn't notice any major effects. My mate was well tripping and was talking about his mind being ahead of his body and stuff, so I guessed it had hit him.
Anyhow we sat for quite a while and then he had to go home (I think at about 9:00pm). This was when the DEX hit me hard. I couldn't walk properly and when I stood up I felt it took ages and I stood up in stages rather than in one fluid movement. I felt I had grown bigger in proportion to the room and that everything had a cartoon like sheen to it. I stumbled into my room and onto my bed. I lay there for ages just thinking. That's the only way I can put it. Thinking about how fucked up I was and how I shouldn't have been persuaded into taking it and about various other things. Time started to go really slow for me. I thought I had been lying on my bed for hours when my girlfriend came into the room and it had only been around 30mins.
The next few hours were like a blur. All I remember were patterns of green and red and alien like visions. Sound was very distorted and I remember being very confused. I saw visions of myself as a young child and visions of me lying in bed when I was younger and having tough times and somehow being comforted by it.
These hours felt like days. I managed to stumble up to feed my cat but my movements were like clockwork. I moved like a clockwork zombie. My brain was telling my limbs to move but they were far behind my thoughts. I remember looking up to see my hand reach out to grab the catmeat and it looked alien somehow. The fact that I could move at all without help or without hurting myself was good I thought, I can't be that fucked up..I let the cat out and felt as though I was seeing reality through a green treacle. Everything was moving in slow mo even sound and it was very strange indeed.
I went to bed and lay there for what seemed like days but it could only have been hours. I didn't want to close my eyes cos this only brought even more intense closed eye visuals which I can only describe as an interlocking lattice of microchips, motherboards and living matter (green and black, looking like something HR Giger would create). At 12:00am my girlfriend joined me and I fell asleep. I cant believe I managed to do this. It was so intense.
The next morning (Monday) I woke up and felt very much still under the influence. My movements were better and easier and my head clearer but there was definitely a fuzziness surrounding me. I wasn't back to reality by any manner of means. I phoned in sick to my work (I definitely had to, everything was still very fucked up) and stumbled back onto my bed to feel sorry for myself and to worry how long this was to last. Again I just lay there and thought about things, about my life and about the fact that I had trouble in the past after taking LSD and stuff and just pondered and pondered...
I 'woke up' (I didn't really sleep) around 2:30 and stumbled in to phone my mate.   It was comforting to know he was fucked up too and that we were recovering somewhat at a similar rate. He laughed and told me he felt strange and could I imagine what this must've done to our minds to leave us in such a state.
I said I would phone him later and went back to bed. My communication faculties were getting back to normal, I noticed this during our conversation, so I felt better and felt I was making a recovery. I went to bed and slept for a thousand years. I woke up at 6:00pm and phoned him again, the two of us felt much the same as before still sluggish with a change in visuals and a grogginess. I told him I was scared that this would
now be normal and that I had suffered brain damage.
He laughed and said I was to phone him at 10:00pm and if we didn't feel better we would see each other at hospital. I laughed and scolded myself for being so melodramatic.  Went up to my brothers house to pick up mail and saw my g/f's mum at her house. Managed to act fairly normal. Offered Chinese takeaway at g/f's mum's. No appetite at all. Haven't eaten since Sunday evening before ingesting the dex. hmm.
Phoned mate at 10:00pm and the two of us were a tiny bit better so we left it at that. He said he was going to bed and I bid him a good night. I went in to watch some TV with my girlfriend and felt a little more positive. I even made (lol) plans to go into my work the next morning.
So, to this morning (Tuesday). I woke up and still felt out of sorts - fuck! I phoned in sick to my work and managed to sound reasonably coherent so I think I am getting better still. Still, there is a buzzing and a perceptual change so everything isn't a-ok just yet. Still a little scared. What have I done to my grey matter? Tell my girlfriend this. Get some breakfast (hunger returning - good sign again!) and go in for a shower. I feel pretty strange still. This is now two days later.
 I manage to go to the bank to pay some bills (I walked btw it is 100 meters or so) and found communicating a hassle. Manage to sort it out. Everything looks too bright, too lucid. Am I coming back to reality? Went to paper shop and didn't want to talk to the shopkeeper. Manage to mumble a conversation but find it scary how hard it is so piece my words together. This was about 3 hours ago.
I thought I better scan all the posts on alt.drugs.psychedelics and find 600 odds waiting. I'm glad I can read them and look for any on DXM for any help on how I am feeling. See one from a poster where he is tripping for a few days but notice this is from a slow release syrup whereas I have taken DXM Hbr powder. Shitcakes.
I am feeling better even as I write this but I haven't been outside for a while and had to communicate with anyone except for my g/f. So we shall see. But my intention of writing all this was to get some advice on a few things. Firstly what plateau do you think I reached. I really cant work it out. I am approx. 170plbs and I think I took about 500mg ( a very rough guess-timate).
Also how long before I return to normal? How common is it for a DXM trip to last this long?
I can feel myself getting better but you just never know. Any side effects I should look out for short/long term?
Thanks for reading, this is more like a trip report now, but I was scared. Still am. But the fact I wrote all this is a good sign right? I think it is written reasonably intelligently without all the spelling mistakes I normally see by DMXers. I'm sure I will be flamed a bit for being such a lamer, and you know what, I deserve it. This is the most intense drug ever.   I was scared especially because of the proximity of taking E and then the dex. Something I've read about this being a really bad idea. Any other thought/comments much appreciated.

Who am I really?
I am a technology enthusiast with wide range of experience in IT field,
both in employments and personal hobbies.
Born in Lahti-city in late April of 1990,
I graduated from high school of Lahden Yhteiskoulu and moved to study at
Aalto University in Otaniemi, Espoo.
Currently,
I live with my veterinarian wife in {{ site.address-city }}.
When I manage to have some freetime
I build and fix electronics and work with my personal coding projects,
play some PC games, or get jumpy with parkour or gymnastics.
Now let's get deep with details.

Also available in Finnish.
Studies and degrees
I graduated from Aalto University's school of Electrical Engineering
with major in Automation and Control Engineering master's program in summer 2022.
I made my bachelor's thesis about Offline Programming of Industrial Robots with excellent grades.
My bachelor's degree included also a variety of courses in Computer Science,
so I constructed the minor of my master's studies from Software Engineering courses.
My master's thesis topic was
Machine learning approach to support ticket forecasting from software logs,
which gave me basic skills and ongrowing interest in machine learning and cloud computing.
Automation and control engineering studies gave me comprehensive mathematical skill set
to be utilized in all sorts of programming tasks.
What am I good at?
My main interest is in user oriented programming and service design.
Decades working as fast food restaurant employee, church camp volunteer
and student union representative made me very social and compassionate person.
Thus, my strength is in understanding other people and solving the issues they might have.
I have utilized this skill successfully when selling overall badges of my own design in different student events.
What I have learned in my employments and studies, is that people rarely understand what they really need.
They might have an idea of the problem they are facing and what they want to fix it,
but they might not realize what the best solution could be.
Interpreting the real problem and "selling" the actual solution to their problem is where I shine.
I'm quick to learn new skills and get exited when I get to try out novel technologies.
My interest has widened from small microcontroller projects to my own Ubuntu media/game/web server hosting.
Writing scripts and developing gadgets for personal use is everyday life for me.
These skills have been useful in my work over the years.

The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Ali Baba is a poor but hardworking woodcutter who finds a thieves’ hideout protected by magic, which he enters by saying, ‘Open Sesame.’ The den is filled with treasures, and Ali Baba lets the secret out to his brother Cassim, who is killed by the thieves while trying to steal the treasure. The thieves find out Ali Baba knows how to get into their hideout, so they set off to kill him, but they are outwitted by Ali Baba’s clever slave, Morgiana.
