…it is getting developers and operations folk to work closely
together to benefit the business.
Barton George
An idiot’s guide to DevOps, Sept 30th, 2013...a software development discipline where you build software in such a way that the software can be released to production at any time.
Continuous delivery is about putting the release schedule in the hands of the business, not in the hands of IT.
...something called “DevOps.” Maybe everyone ... is a form of DevOps, but I suspect it’s something much more than that. It’s Product Management, Development, IT Operations, and even Information Security all working together and supporting one another.
...true agility means that teams are constantly working to evolve their processes to deal with the particular obstacles they are facing at any given time.
...willing to challenge everything: the status quo, internal siloes, and immovable strategies
... erasing the lines between business and technology
... hiring, empowering, and growing multidisciplinary, future-ready employees
... investing in platforms that allow their businesses to get ideas to market in weeks, not months

This specification defines a process and a document format to allow a user agent to update an installed widget package with a different version of a widget package. A widget cannot automatically update itself; instead, a widget relies on the user agent to manage the update process.
This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.
Note: The working group reached consensus to stop work on this specification. It is being published for archival reasons and is no longer being progressed along the W3C's Recommendation Track.
User agents that wish to extend this specification in any way are encouraged to discuss their extensions on a public forum, such as public-webapps so their extensions can be considered for standardization.
This specification is part of the Widgets Family of Specifications.
This specification takes into account the recommendations from the Widget Updates Patent Advisory Group and considering the set of prior art the Patent Advisory Group found.
This document was published by the Web Applications Working Group as a Working Group Note. If you wish to make comments regarding this document, please send them to<EMAIL_ADDRESS>(subscribe, archives). All comments are welcome.
Publication as a Working Group Note does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) must disclose the information in accordance with section 6 of the W3C Patent Policy.
This section is non-normative.
There are a multitude of reasons why an author of might want to update an application including:
Sometimes an author may even want to revert back to a previous version of an application, if it is found that a newly deployed version of a application contains issues or vulnerabilities.
To facilitate the process of updating widgets, this specification introduces an XML element, called an update description source, that is included as an Extension to the Configuration Document of a widget package. This specification also introduces a new XML vocabulary, called an update description document. The update description source provides an author with a means to point to an update description document.
An update description document is metadata about a widget update including:
a means to describe the purpose of the update.
a means to indicate the version identifier for the potential update.
a link to where the potential update widget package can be retrieved from.
If a user agent determines, after Acquiring an Update Description Document and during Processing an Update Description Document, that two widget packages are not the same version, and if the user consents, the user agent will attempt to replace the currently installed widget with the potential update. Updates are designed to retain any locally stored data, so to protect end-users from losing data that a widget may have stored at runtime.
A user agent must support the capability to acquire an update description document over HTTP protocols. For non-HTTP protocols, UAs should act in equivalent ways.
This specification also discusses the Security Considerations that are left up to the discretion of implementers.
As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.
The key words MUST, MUST NOT, REQUIRED, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL in this specification are to be interpreted as described in [RFC2119].
This specification defines conformance requirements for a single class of product: user agents.
The concepts of a widget package, a configuration document, a valid IRI, a version attribute, user agent locales, global attributes and the definition that one element is allowed per language are defined in the [WIDGETS] specification.
A user agent is an implementation of this specification that also implements the [WIDGETS] specification and its dependencies.
An installed widget is a widget package [WIDGETS] that has been correctly installed and currently resides on or within a user agent.
An update description source is the URI pointing to the location of an update description document.
An update description document is an [XML10] document that has a update-info
element at its root.
An update source is the URI referenced by the src attribute of an update-info
element within an
update description document.
A potential update is a resource acquired via HTTP (from an update source) or from local media.
The widget update process is a multi-step process whereby a user agent acquires a potential update, performs the rule for verifying a widget update, and then proceeds to install the widget package.
The identity of a widget package [WIDGETS] is determined by the id attribute of the widget
element declared by an author in the configuration document [WIDGETS] of a widget package [WIDGETS].
The version of a widget package [WIDGETS] is determined by the version attribute of the widget
element declared by an author in the configuration document [WIDGETS] of a widget package [WIDGETS].
An incumbent widget is an installed widget that is determined to have the same identity as the potential update.
An installed widget is said to be up-to-date if a user agent determines that an incumbent widget does not need updating.
A failure notification is an optional message emitted by the user agent to indicate to the user that a widget update has failed.
Note: This specification does not define the means or format of a failure notification, which is left up to implementers.

The update-description
element points, via the href attribute, to an update description

</widget>
update-description
elements in the Configuration Document
The user agent MUST process a configuration document [WIDGETS] containing an update-description
element according
to the rule for processing the update-description element.
The rule for processing the update-description element is defined as follows.
| Variable | Type | Default Value | Overridden in | Description |
|---|---|---|---|---|
| update href | URI |

element and its descendants.update-description
element and the href attribute is used, and it is a
valid IRI [WIDGETS], then let update href be the value of the href attribute.
Otherwise, this element is in error and the user agent MUST ignore this element. Within an update description document an author declares, amongst other things, what's new or different in the potential update, the version that the widget will be updated to, and the update source from where the user agent can retrieve the potential update.
The purpose of the update description document is to provide the details about a potential update, including a pointer to a HTTP resource that will act as the potential update.
In order for a user agent to retrieve and process an update description document, an author will initially declare a
valid IRI [WIDGETS] for the update-description
element in the installed configuration document (e.g.
<update-description href="https://example.com/myWidget/updates"/>
), as defined in the Update Extensions to Widget Configuration Documents section.
Below is an example of a typical update description document.
<update-info xmlns = "http://www.w3.org/ns/widgets"
src = "https://w.example.com/2.1/RC/app.wgt"
version = "RC2.1">

</update-info>
It is expected that user agents will perform a widget update process asynchronously and periodically check for any available updates. The timing of any widget update process is an implementation detail left to the discretion of the implementer (e.g. once a day or once a week).
To check for updates to a widget, the user agent issues a HTTP request towards the update description source.
The user agent MUST send the last known ETag response value, if available, in an If-None-Match header.
The user agent MUST send an If-Modified-Since header indicating the time of the last check for an update from the user agent.
The user agent MUST send an Accept-Language header representing the widget's locale.
As data is received, the user agent will then act as follows.
The user agent MUST ignore any Cache-Control or Pragma header with a value of no-cache
.
The user agent MUST honor the value of any Expires header when scheduling the next widget update process for the current installed widget.
The user agent MUST process HTTP 200 OK responses, with a Content-Type header specifying the type application/xml
,
according to the rules defined in Processing an Update Description Document.
The user agent MUST terminate the widget update on HTTP 200 OK responses that have a Content-Type other than application/xml
.
On receiving HTTP 204 No Content, 205 Reset Content, and 304 Not Modified responses, the user agent MUST terminate the widget update.
On receiving HTTP response codes in the 2xx range, other than HTTP 200 OK, the user agent MUST terminate the widget update. They are, however, likely to indicate an error has occurred somewhere and may cause the user agent to emit a warning.
On receiving HTTP 301 Moved Permanently, 302 Found, 303 See Other, and 307 Temporary Redirect responses, the user agent MUST reconnect using the new server specified URL instead of the previously specified URL.
The user agent SHOULD treated HTTP 305 Use Proxy, 401 Unauthorized, and 407 Proxy Authentication Required responses transparently as for any other subresource.
On receiving an HTTP 410 Gone response, the user agent must terminate the widget update and remove the installed widget.
Any other HTTP response code not listed here, and any network error that prevents the HTTP connection from being established in the first place (e.g. DNS errors), must cause the user agent to terminate the widget update.
A user agent MUST assume the following defaults prior to processing an update description document:
| Variable | Type | Default value | Description |
|---|---|---|---|
| update-source | URI |
null
|
|
| version-tag | DOMString |
null
|
|
| details | DOMString |
null
|
A user agent MUST process an update description document according to the rule for processing an update description document.
The following processing model is written with more concern for clarity over efficiency. As such, a user agent can optimize the processing model so long as the end result is indistinguishable from the result that would be obtained by following the specification.
The term in error, typically used on an element or attribute, means that the element, attribute, or other construct does not conform to the rules of this specification. Rules for exactly how a user agent needs to treat the erroneous construct are always given when the term is used.
When an invalid update description document is determined then the user agent MUST terminate the widget update.
The rule for processing an update description document is defined as follows:
Document
using a [XML-NAMES]-aware parser. If the document is not well-formed [XML10], then treat this as an
invalid update description document.
documentElement
of doc.
update-info
element in the widget namespace, then treat this update
description document as an invalid update description document.
update-info
element:
version
attribute was used, and it is a valid version attribute [WIDGETS], then let version-tag
be the value of version
.
version
attribute was used, or the value was in error, treat this as an invalid update
description document.
details
element:
details
element, in document order, that
matches a language range in the user agent locales; or, if no details
element in the document matches the user agent locales and this is not the first element; then the element is in error and MUST be
ignored.
When a user agent is to install the widget package it is to remove the installed widget and then add the potential update as an installed widget.
When a user agent is to remove the installed widget it is to disable the current incumbent widget, if it exists. The user agent may also physically remove the incumbent widget from the device. The user agent may emit a notification warning that the incumbent widget is being removed.
When a user agent is to terminate the widget update it is to terminate the current widget update process. The user agent may emit a failure notification warning that the widget update has been terminated.
To verify and install a potential update the user agent must apply the rule for verifying a widget update.
The rule for verifying a widget update enables a user agent to match and verify a potential update - acquired via HTTP or from local media - with an installed widget package [WIDGETS] and is defined as follows:
Note: The decision of which (if any) distributor signatures are to be validated and whether the author signature is to be validated is out of scope [WIDGETS-DIGSIG].
dsp:Identifier
value [WIDGETS-DIGSIG] from update_signature with the same
value obtained from the associated incumbent_signature within incumbent_digsigs.
Because an update description document is not self-contained, it is conceivable that the update model could be subject to a man-in-the-middle attack, as with any unencrypted requests performed over [HTTP11]. For this reason, it is RECOMMENDED that, for widgets that have not been digitally signed, updates are always performed over [HTTP-TLS].
Another means of protection is for authors to always digitally sign their widget resources. During an update, the user agent will then validate the signature before installation, ensuring that a widget resource's identity and integrity was maintained over the network.
An authoritative update URI is an update description source referenced in the href attribute of an
update-description
element within an installed widget's configuration document [WIDGETS].
Without the availability of a digitally signed installed widget, it is extremely easy to overwrite a widget resource with another (potentially malicious) widget resource. Therefore it is RECOMMENDED that a user agent only allow updates to a signed installed widget or to a non-signed installed widget only from a potential update obtained via its authoritative update URI.
This section is non-normative.

Hi there! We're stoked that you want to be a speaker at our conference.
We welcome you to our stage: both expert level speakers and absolute beginners who have never given a talk before.
Here's what you can expect as a speaker for .NET Fringe:
The first step to becoming a speaker for .NET Fringe is to submit a proposal for a talk. We accept proposals at any time, via GitHub pull requests, but each year we open a Call For Proposals (CFP) and there is a cut off date for the talks we'll consider for that year's schedule.
Go ahead submit a talk!
After the CFP closes, our organizer team uses a two step selection process. The first step involves a vote by the entire organizing team. The voting scores create a sorted list of talks. From that, the CFP Czar will select the talks they think will make an interesting schedule (not necessarily the most highly voted talks).
At that point, we will reach out to you, to let you know your talk was accepted, and ask you to confirm that you can still make it to the conference. If you say yes, we'll move on to the next step.
Once the schedule is filled with confirmed speakers, the CFP Czar will send out notices to everyone whose talk didn't get selected with an offer for a discounted ticket and invitation to deliver a lightning talk during the conference.
Once you are a confirmed speaker on our schedule there are a number of things we need to do to prepare you for the conference:
We'll need a square photo, and a link to your preferred online presence (typically Twitter or GitHub account). We'll add you to the site and place you on the schedule.
Once you're on the site, we'll tweet about your talk from our official @dotnetfringe account. We encourage you to follow that account, and to retweet anything related to your talk. It'd also be great if you tweeted about your talk. We'll RT that if you do. :)
We'll also send out regular emails to the attendees letting them know about confirmed speakers.
.NET Fringe will gladly help you with travel costs if you are a speaker at our conference. We will reimburse up to $500 for domestic travelers and $1000 for international travelers. We will also cover your hotel stay for up to three nights.
Generally, we expect you to book your own travel and lodging, then deliver receipts, so we can reimburse you at the end of the conference. If your funds are particularly tight, on a case-by-case basis we can help you book travel, and cost-effective lodging that is close to the venue.
The next big step is preparing your talk and delivering it at the conference. If you're a first time speaker, this can be particularly intimidating. We're glad to help you out and can pair you up with an experienced mentor to work through all the nuances.
Some important things to check:
Great! You've given your talk and everyone loved it. Now is the time to upload your slides to the interwebs somewhere so folks can reference them later. You're welcome to host those in our Github repo, just file a PR! Once they are up there, it's best to tweet out a link to the slides, and we'll RT you if you do.
We also record video of all the talk and release those shortly after the conference. The videos are released with title slides and are licensed under Creative Commons. This is a great way to make the content available to a much wider audience and functions as a handy resume of your prior speaking experience. If you don't want your video published, please let us know as early as possible.
You can see examples videos of talks from previous years here: https://www.youtube.com/channel/UCIz73jo7KPqVTssbUmiIfXg

Backtesting Triple Miss Stocks in R
Backtesting possible short positions by examining stocks that miss EPS and revenue estimates and lower forward guidance reveals that the behavior of these Triple Miss stocks offers a profitable opportunity over the short-term.
Goal
Bespoke Investment Group offers a stock screen feature that “allows users to run in-depth earnings report screens and easily filter more than 150,000 individual quarterly reports for US stocks since 2001.”
They also offer a report showing what they have termed an Earnings Triple Play - that is a stock that “beats consensus analyst EPS estimates, beats revenue estimates, and raises forward guidance.” The term has become so well known that none other than Investopedia have given Bespoke credit for it. These stocks are the best candidates for long-term buy opportunities.
But is the opposite also true? Does a stock that misses consensus analyst EPS estimates, misses revenue estimates and lowers forward guidance a terrible long-term buy opportunity and a possible short opportunity? We can refer to these stocks in this category as a Triple Miss.
The goal is to quantify whether a Triple Miss makes a good short opportunity starting the day after the announcement.
Get the Data
Extract the Stock Symbols and Dates of Each Triple Miss
Using the aforementioned stock screener, I researched Triple Miss stocks in 2018, and downloaded a .csv file of the data. Turns out there were 132 Triple Miss instances (with 104 different stocks - some companies were listed more than once!) in 2018. On an aggregate basis, this was the return:
After reading in the data in R, I extracted the symbols and dates of each Triple Miss.
#create a list of symbols that can be read in symbols <- unlist(temp$ticker) ticker <- as.character(unlist(temp$ticker)) #get list of dates of triple miss dates date <- as.Date(unlist(temp$date))
Once this was created, I tried to use the quantmod() package to look-up the historical data. quantmod() is wonderful for looking up individual stocks and analyzing them, but it is a challenge to deal with multiple stocks on varying dates of interest.
Get Historical Stock Data
Enter the batchgetsymbols() package.
As the creator of the package lamented:
In the past I have used function GetSymbols from the CRAN package quantmod in order to download end of day trade data for several stocks in the financial market. The problem in using GetSymbols is that it does not aggregate or clean the financial data for several tickers. In the usage of GetSymbols, each stock will have its own xts object with different column names and this makes it harder to store data from several tickers in a single dataframe. Package BatchGetSymbols is my solution to this problem. Based on a list of tickers and a time period, BatchGetSymbols will download price data from yahoo finance and organize it so that you don’t need to worry about cleaning it yourself.
The batchgetsymbols() package worked beautifully to download all of the historical data for each stock going back to 2018 and return it in one giant, clean dataframe.
#<-----TRIPLE MISS ANALYSIS -----> #Batch download symbols - change type.return to "log" for log l.out <- BatchGetSymbols(tickers = ticker, first.date = start.data, last.date = end.data, type.return = "arit", freq.data = freq.data) #get a list of tickers that were downloaded all.ticker <- l.out$df.control$ticker
Filter Out Data Prior to Triple Miss
After getting the dataframe set-up, I used the dplyr() package to filter out data prior to the Triple Miss announcement. This was required because I only wanted to look at the performance of the stock after the date of the Triple Miss. I then created a new data frame to hold this data using the bind_rows() function.
#filter out all data before entry date by ticker b <- mapply(function(a,b)(l.out$df.tickers %>% filter(ref.date > a, ticker == b)),date,ticker,SIMPLIFY = F) #create new df without the post entry date data b1 <- bind_rows(b) summary(b1$ret.closing.prices)
Examine the Aggregate Stock Data
Interestingly, the average cumulative daily return for each stock measured from the date of the Triple Miss to the date of this post has been 4.28% - that means an average annual return of 1.36%. The average daily return is .005%. On an annualized basis, this is a Sharpe Ratio (return/volatility) of 0.59 - clearly a lot of volatility for not a whole lot of return!
b2 <- b1 %>% select(ref.date,ticker,ret.closing.prices) %>% group_by(ticker) %>% summarise(Mean_Daily_Return = mean(ret.closing.prices,na.rm = TRUE)*100, Cum_Daily_Return = sum(ret.closing.prices,na.rm = TRUE)*100) %>% arrange(Cum_Daily_Return) > mean(b2$Cum_Daily_Return) [1] 4.281108 > mean(b2$Mean_Daily_Return) [1] 0.00539823 > mean(b2$Mean_Daily_Return)/sd(b2$Mean_Daily_Return)*sqrt(252) [1] 0.5942328
Examine the Aggregate Stock Data 1, 5 and 10 Days After Triple Miss
What if we shortened the window for analyzing the returns of all of the Triple Miss Stocks? Do the effects of the Triple Miss “wear off” at a certain point or do they continue?
The Triple Miss stocks are very negative - below is a chart with the cumulative return from 1 to 10 days after each Triple Miss.
On an individual basis, you can see the downward trend each stock exhibits post-Triple Miss.
On an aggregate basis after 10 days:
- 71 out of the 113 stocks (approximately 63%) had a negative cumulative daily return 10 days after the Triple Miss,
- each stock had an average daily return of -0.58% and cumulatively lost 4.55% in value by day 10, and
- had an average Sharpe Ratio (average daily return divided by average standard deviation of the daily returns) of -5.57.
In short, the returns were less than spectacular.
Over 5 days, returns were even worse:
- 66 out of the 113 stocks (approximately 58%) had a negative cumulative daily return 5 days after the Triple Miss,
- each stock had an average daily return of -1.46% and cumulatively lost 5.26% in value by day 5, and
- had an average Sharpe Ratio of -6.50.
And the day after a Triple miss? 95 of 113 (84%) were down day-over-day by an average of 6.86% with a Sharpe Ratio of -10.62.
Conclusion
It seems clear that Triple Miss stocks would be a good place to start when looking for stocks to short over the near-term. Obviously, this is not a recommendation to buy or sell; you would need to do your own research and make your own decision to determine that. But the Triple Miss stocks might be a good filter to start looking for opportunities.

BUFR Table C - Data description operators (Edition 3, Version 11-05/11/2003)
|
F |
X |
Y |
OPERATOR NAME |
OPERATION DEFINITION |
|
2 |
01 |
Y |
Change data width |
Add (Y-128) bits to the data width given for each data element in Table B, other than CCITT IA5 (character) data, code or flag tables |
|
2 |
02 |
Y |
Change scale |
Add Y-128 to scale in Table B for elements which are not code or flag tables |
|
2 |
03 |
Y |
Change reference values |
Subsequent element descriptors define new reference values for corresponding Table B entries. Each new reference value is represented by Y bits in the Data section. Definition of new reference values is concluded by coding this operator with Y = 255. Negative reference values shall be rep resented by a positive integer with the left-most bit (bit 1) set to 1 |
|
2 |
04 |
Y |
Add associated field |
Precede each data element with Y bits of information. This operation associates a data field (e.g. quality control information) of Y bits with each data element |
|
2 |
05 |
Y |
Signify character |
Y characters (CCITT International Alphabet No. 5) are inserted as a data field of Y x 8 bits in length |
|
2 |
06 |
Y |
Signify data width for the immediately following local descriptor |
Y bits of data are described by the immediately following descriptor |
|
2 |
21 |
YYY |
Data not present |
Data values present in Section 4 (Data section) corresponding to the following YYY descriptors shall be limited to data from classes 1-9, and class 31 |
|
2 |
22 |
000 |
Quality information follows |
The values of class 33 elements which follow relate to the data defined by the data present bit-map |
|
2 |
23 |
000 |
Substituted values operator |
The substituted values which follow relate to the data defined by the data present bit-map |
|
2 |
23 |
255 |
Substituted values marker operator |
This operator shall signify a data item containing a substituted value; the element descriptor for the substituted value is obtained by the application of the data present bit-map associated with the substituted values operator |
|
2 |
24 |
000 |
First order statistical values follow |
The statistical values which follow relate to the data defined by the data present bit-map |
|
2 |
24 |
255 |
First order statistical values marker operator |
This operator shall signify a data item containing a first order statistical value of the type indicated by the preceding 0 08 023 element descriptor; the element descriptor to which the first order statistic relates is obtained by the application of the data present bit-map associated with the first order statistical values follow operator; first order statistical values shall be represented as defined by this element descriptor |
|
2 |
25 |
000 |
Difference statistical values follow |
The statistical values which follow relate to the data defined by the data present bit-map |
|
2 |
25 |
255 |
Difference statistical values marker operator |
This operator shall signify a data item containing a difference statistical value of the type indicated by the preceding 0 08 024 element descriptor; the element descriptor to which the difference statistical value relates is obtained by the application of the data present bit-map associated with the difference statistical values follow operator; difference statistical values shall be represented as defined by this element descriptor, but with a reference value of -2n and a data width of (n+1), where n is the data width given by the original descriptor. This special reference value allows the statistical difference values to be centred around zero |
|
2 |
32 |
000 |
Replaced/retained values follow |
The replaced/retained values which follow relate to the data defined by the data present bit-map |
|
2 |
32 |
255 |
Replaced/retained value marker operator |
This operator shall signify a data item containing the original of an element which has been replaced by a substituted value. The element descriptor for the retained value is obtained by the application of the data present bit-map associated with the substituted values operator |
|
2 |
35 |
000 |
Cancel backward data reference |
This operator terminates all previously defined back- ward reference and cancels any previously defined data present bit-map; it causes the next data present bit-map to refer to the data descriptors which immediately precede the operator to which it relates |
|
2 |
36 |
000 |
Define data present bit-map |
This operator defines the data present bit-map which follows for possible re-use; only one data present bit-map may be defined between this operator and the cancel use defined data present bit-map operator |
|
2 |
37 |
000 |
Use defined data present bit-map |
This operator causes the defined data present bit- map to be used again |
|
2 |
37 |
255 |
Cancel use defined data present bit-map |
This operator cancels the re-use of the defined data present bit-map |
Notes:
(1) The operations specified by operator descriptors 2 01, 2 02, 2 03 and 2 04 remain defined until cancelled or until the end of the data subset.
(2) If change scale is used, then it may be necessary for the originator of the message to supply an appropriately rescaled reference value and data width.
(3) Cancellation of the use of the redefined value shall be effected by the inclusion of the appropriate operand with Y set to 0. The value shall then revert to the original Table B value.
(4) Nesting of operator descriptors must guarantee unambiguous interpretation; in particular, operators defined within a set of replicated descriptors must be cancelled or completed within that set.
(5) Nesting of the operator descriptor 2 04 is defined such that:
(a) Each new definition adds to the currently defined associated field;
(b) Each cancellation (2 04 00) cancels only the most recently defined addition to the associated field.
(6) When the descriptor 2 04 YYY is to be used, it shall precede the first of the data descriptors to which it applies.
(7) The data description operator 2 04 YYY shall be followed immediately by the descriptor 0 31 021 to indicate the meaning of the associated fields.
(8) In the data stream, the 6 bits described by 0 31 021 shall precede the YYY bits.
(9) Once an associated field has been established and given meaning, the meaning may be changed by a re-application of descriptor 0 31 021. The associated field needs not to be cancelled in order to change the meaning. Further, if an associated field is cancelled, and then re-established, it must be given a meaning by a proper application of the 0 31 021 descriptor, as described in Notes (5) to (8), i.e. a previous assignment of meaning does not remain in force when the associated field is cancelled.
(10) Data description operators shall not be applied to Table B, class 31 entries.
(11) The operation 2 05 permits the inclusion of plain language.
(12) The operator 2 06 Y allows for the inclusion of local descriptors in a message, with their associated data, which can then be by-passed by a receiver of the message. It can be applied to element descriptors (F = 0) only.
(13) If "replaced/retained" values are indicated, this shall imply that the data element in the original part of the message has been replaced with a (presumably) better value; the original value has been retained in the message following the replaced/retained operator. If multiple replacements for the same data element are to be included, they shall be ordered such that the original datum shall be last, the first replacement shall precede it, the next precede that, etc. Each (set of) replaced/retained data values shall be indicated by the inclusion of the 2 32 000 operator.
(14) If "substituted values" are indicated, this shall imply that the data element in the original part of the message is thought to be of poor quality. However, it has been left in the original message as received; an improved value has been placed within the message following the substituted values operator. If multiple substitutions for the same data element are to be included, they shall be ordered such that the first substitution shall be first, the next substitution shall follow it, the next follow that, etc. Thus, the (presumed) "best" value will be found at the end of the collection of substituted values. Each (set of) substituted data values shall be indicated by the inclusion of the 2 23 000 operator.
(15) Operator 2 21 YYY allows for the construction of a BUFR message containing only coordinate (classes 1-9), delayed replication (class 31) and quality control information. The message could be linked back to the original data-containing message by comparison of the coordinate information in the two messages, or, in a local context, through "database" information in Section 2.
(16) First-order statistics have values with a similar range and the same dimensions as the corresponding reported values (e.g. maxima, minima, means, etc.).
(17) Difference statistics are difference values; they have dimensions the same as the corresponding reported values with respect to units, but assume a range centred on zero (e.g. the difference between reported and analysed values, the difference between reported and forecast values, etc.).
(18) No operator descriptors are reserved for local use.

I recently had the pleasure of creating a mobile version of HTML5Rocks and later wrote up my experiences in "Mobifying" Your HTML5 Site. In fact, the project was my first real endeavor into mobile web development. All in all, I'd say the experiment was a great learning experience. While developing a mobile version of this site was fun, the most important takeaway from the challenge was what I learned about debugging mobile web apps. Let's be honest. It can be a real PITA!
The goal of this article is to help steer you in the right direction the next time you develop for the mobile web. I'll give you the best techniques I discovered when developing mobile html5rocks.com. There's probably plenty more that could be covered, but we'll leave that for another time :)
The number one tool I found when developing mobile HTML5Rocks was to use the desktop web browser to develop and debug mobile web apps. That may or may not be obvious to people, but it was not obvious to me.
Turns out the desktop browser is a fantastic tool for debugging a mobile web app! Being an absolute noob, my first instinct was to download the Android SDK + Emulator and iOS simulator and fire up the site in them. After 5 minutes of putting up with the horrifically slow Android emulator, it was clear I needed something better.
Modern browser include excellent developer tools. In Chrome or Safari, you can use the Developer Tools to debug JavaScript, inspect DOM elements, and change CSS styles on-the-fly. Firefox has Firebug, which has similar capabilities. When I was debugging the site's CSS media queries, the Dev Tools became a life saver.
Sometimes, it's handy to change the browser's User Agent. The obvious reason is to
more closely mimic the experience of the native device. As an example,
the App Engine server behind HTML5Rocks omits certain functionality, template sections,
and site features if the user is visiting on mobile. A boolean true
is passed to our Django templates if the user is visiting on a smart device (for us: IOS or Android).
Hence to test the site as mobile Safari (from desktop Safari), some UA spoofing was required.
Luckily, some browsers make this super easy to do.
My recommendation is to use Safari for testing User Agent issues, for two reasons:
To enable the 'Develop' menu in Safari, check 'Show Develop menu in menu bar' under Advanced > Preferences.
Under the Develop menu, you can easily switch the browser's UA:
Lastly, for the browser that do not natively support User Agent switching, there are some nice plugins available, particularly for Firefox.
After switching to a mobile UA, the next piece of the puzzle is resize the browser to size of the mobile device. The reason is really two-fold. First, you can more optimally visualize and design your site when you know what kind of screen real-estate is available. Secondly, testing CSS media queries becomes trivial. We actually use media queries all over the place in the mobile version of html5rocks.com. To see what I mean, start resizing this window. The UI should change significantly (especially in the top header) as the page gets smaller. Whenever we needed to override a default styling, CSS media queries proved to be invaluable.
For Android and iPhone, the screen-size is typically 320px. For iPad, it's more like 768px for portrait and 1024px for landscape. To save yourself the trouble of manually figuring out the correct size, I've created handy bookmarklets to load a page at each size:
Drag these bookmarklets to your bookmarks bar:
768px (ipad-portratit)
1024px (ipad-landscape)
320px (iPhone/Android)
The unobfuscated code looks something like this:
var w = window.open(location.href, 'mywin', 'height=' + document.height + ',width=768'); w.resizeTo(768 + window.innerWidth - document.body.clientWidth, document.height);
The resize takes into account the scrollbar width since they're essentially width=0 on mobile.
When all is said and done, the desktop browser is but one way to test media queries. There are plenty of other tools out there, though. A couple of examples are resizemybrowser.com and iOS Media Query Previewer.
This article won't cover downloading and installing the iOS or Android SDKs. Apple and Google have great documentation for that at http://developer.apple.com/devcenter/ios/index.action and http://developer.android.com/sdk/index.html, respectively.
At some point you'll need to fire up an emulator to test in the "real deal". There's no way around it. In my opinion, there are 3 big emulators that you need to include in your testing workflow:
This is by no means an exhaustive list. A complete list can be found in "Mobile Emulators & Simulators: The Ultimate Guide".
Since we're talking web apps here, you'll inevitably have some kind of server
component to your application...unless you're building a toy :) Accessing a local
development server is straightforward on the iOS Simulator. Just hit http://localhost
(or similar) in mobile Safari, and you're off and rolling. Doing the same on the
Android Emulator is a bit trickier.
To setup Android Emulator for testing a local dev server, do the following:
The reason the iOS Simulator is so much easier, is because it is just that, a simulator. It uses the host operating system (MacOSX 10.6+) for its network stack, memory, etc. Android's emulator is a true emulator. It actually fires up a VM, which also one of the core reasons it is painfully slow.
It is my personal feeling that should be using AppCache on mobile. Not only does it offer users offline content, but it can also speed up the initial load of your site. Loading assets from an guaranteed cache is much more reliable than relying on browser caching. Our mobile version of HTML5Rocks uses AppCache for both of these reasons.
That said, developing a mobile app that uses Application Cache can be annoying. For example, you may forget it's turned on and wonder why browser refreshes aren't reflecting your changes. Clearing the browser cache doesn't help either because AppCache uses its own (magic) storage bin. Another problem is that AppCache requires two page refreshes to reflect new changes (one to pull download the updated assets and another to actually see the changes).
To save you some frustration, I have two tips for debugging AppCache:
updateready
event. This will insure
you're always viewing the latest content.1. When implementing AppCache it is extremely important that you don't cache your manifest file (either explicitly in the manifest file itself or implicitly with heavy cache control headers). If your manifest gets cached by the browser it's a nightmare to debug. iOS and Android do a particularly good job of caching this file but don't provide a convenient way to flush the cache like the desktop browsers do.
2.  Again, mobile Safari and Android do not provide a friendly way to clear the AppCache data on demand. Here is one way to handle this problem:
window.applicationCache.addEventListener('updateready', function(e) { if (window.applicationCache.status == window.applicationCache.UPDATEREADY) { window.applicationCache.swapCache(); if (confirm('A new version of this site is available. Load it?')) { window.location.reload(); } } }, false);There are remote debugging tools weinre, jdrop, mobileperf {% endblock %}


Welcome to our blog! We appreciate your time and attention and sincerely hope that you will be able to take away something useful from reading this. In this inaugural blog post, we will explain our thoughts on stablecoins: where the space currently is at, what the future holds, and how we see our website fitting into the big picture.
Stablecoins are a relatively recent innovation to the cryptocurrency space and have been a product of many of the lessons learned from the first several years of cryptocurrencies being in existence. Describing what stablecoins are is straightforward enough: they are cryptocurrencies that aim to maintain a fixed price (e.g. $1.00). Explaining how they work is more complicated. For more information on that we have put together a relatively brief explanation here. Even more challenging is putting the rise of stablecoins into context in the rapidly evolving cryptocurrency landscape.
At their core, stablecoins are a compromise between the two major forces at play in shaping the cryptocurrency space: ideology and practicality. Stablecoins are a departure from the radically libertarian bent of cryptocurrencies to transcend the use of fiat currencies entirely and replace the US Dollar, the Federal Reserve, and the global monetary system at large with a new monetary system based entirely on something new. Commitment to this ideology has proven to be a liability for the adoption of cryptocurrencies as the dependence of the economy on the current monetary system is deeply entrenched. The resulting inertia has limited the real world applications of cryptocurrencies. The economic advantages of clearing on the blockchain simply cannot not outweigh the operational overhead and risks of transacting in an entirely new currency, especially given its extreme price volatility.
By tying the value of a cryptocurrency to fiat currencies instead of trying to replace them, stablecoins can address the issue of practicality. Stablecoins would have the same immediate economic function as - and therefore can be used interchangeably with - fiat currencies, eliminating many of the issues that would otherwise be associated with using cryptocurrencies. Consequently, the decision of whether to use stablecoins or fiat comes down to a matter of which transaction clearing infrastructure is faster and less expensive, an area in which the blockchain excels.
Even though stablecoins take a step back in ideology, they still embody many of the principles of cryptocurrencies. By allowing real-world transactions to clear on a decentralized blockchain, stablecoins offer a compelling alternative to the existing financial services industry, which is often characterized as an oligopoly that lacks sufficient competition to incentivize proper innovation, an inevitable consequence of being too centralized. In fact, by being more immediately viable than other long-term cryptocurrency designs, stablecoins represent a more direct competitive threat to the status quo and are well postured to effect positive change on this very important aspect of the economy.
Despite the vast potential of stablecoins to streamline how capital flows throughout the economy, the reality of the situation is that the stablecoin space is still very much in its infancy. There are only a handful of stablecoins that are currently live (several have recently been released and many more are on currently in development). Many of the live projects are based on relatively primitive protocols as they are backed by fiat-collateral and are managed by a centralized organization, essentially sacrificing ideological consistency with the fundamental principles of cryptocurrencies to release a stablecoin product as expediently as possible. For example, the dominant early leader in the stablecoin space, Tether is operated by a centralized organization, and there is already substantial criticism of its transparency and allegations of market manipulation, which are incidentally the exact issues decentralization was intended to address. There are more ambitious stablecoin projects such as MakerDao and Basis that aim to maintain price stabilization with decentralized protocols, but they are still in relatively early stages as the complexity of the protocols naturally results in a longer design cycle and a slower adoption rate.
Currently, the vast majority of the use cases of stablecoins are related to facilitating cryptocurrency trading. Stablecoins solve many of the operational challenges of trading into cash positions since clearing off-blockchain fiat transactions is substantially slower and more onerous than the corresponding on-blockchain cryptocurrency transactions. With stablecoins, cryptocurrency traders are able to execute trades faster and more efficiently, which is a compelling reason to use stablecoins in lieu of fiat, even if most existing options are not quite optimally designed.
Given that stablecoins are still in such an early phase of development and adoption, there is still a substantial amount of potential to be realized. The use cases of stablecoins extend far beyond the reach of facilitating the cryptocurrency trading. Based on the speed of clearing and the unit economics of each transaction on the blockchain, stablecoins represent a compelling alternative to a broad spectrum of financial services ranging from checking accounts, point-of-sale services like credit cards, and peer-to-peer payments like Venmo and PayPal. These applications can be competitive with existing options because a decentralized architecture has fundamental advantages over the centralized paradigm of the status quo. In the long run, better and cheaper transaction clearing services will eventually subsume the less efficient options that are currently used.
However, this future of stablecoins being actively competitive with fiat currencies is by no means inevitable, and it definitely cannot be taken for granted. There remains a substantial amount of work that must be done to make the stablecoin ecosystem truly competitive with the fiat currencies. While most contemporary efforts are focused on developing the core stabilization technology, there will soon be promising opportunities to build full-service end-to-end applications of stablecoins that provide the same financial services that are currently offered for fiat currency once the underlying infrastructure has been established. After all, the industries that stablecoins are poised to disrupt have had a considerable head start in developing application-layer technology, which is ground that the stablecoin ecosystem will have to cover to match and hopefully surpass the fiat currency system.
As the domain of stablecoins continues to mature and evolve, knowledge sharing is crucial. Our mission with Stablecoin Compare is to coalesce all of the valuable empirical information that is observed on stablecoins into a conveniently accessible location for use by adopters, investors, developers, traders, and whoever else may be involved in bringing this new technology into the mainstream. Given where we currently are in the development and adoption curve, there remain many questions yet to answer about which stablecoin implementations are the most effective. There are many design decisions that go into developing each stabilization protocol, and these decisions will ultimately determine how closely each stablecoin’s price dynamics will adhere to its peg. It is our intention with Stablecoin Compare to track these design decision differences between different stablecoin projects and to measure empirical metrics on how successful each stablecoin is at maintaining price stability. Our hope is that our users can use this to make more informed decisions about which specific stablecoins implementations to use, invest in, or develop applications on top of.
If you have any suggestions for information or analytics on stablecoins that you think would be useful to have on our site, please let us know. We gladly welcome any feedback on how we can improve our site. Thank you for your time!

Threats and Preventions
Microsoft, explains that phishing is a kind of “social engineering attack” which consists of using deceiving emails to hoax victims into sharing sensitive information such as passwords, credit card details and other personal information. Those emails are often try to imitate an email from trusted companies to again the trust of the users that are being targeted. The main concept of this attack that instead of targeting the system, it’s the users using these systems are the targets. As seen in the Anti-Phishing Working Group, 2017 report the number of users targeted are very high with number as high as 51, 265 in March of 2017 for number of unique phishing websites detected.
Anti-Phishing Working GroupDo not open messages from users that you do not know and do not open any links that they send you. (Avast)
Do not share your information with any one the internet unless you are sure that the source is secure. (Kaspersky Lab)
Do not open any links on Tumblr which you are unsure about and if you do don’t share any personal information on those websites. (Kaspersky Lab)
Do not trust a source on the basis that there are likes and comments on the post, those can be fake comments and likes. (Kaspersky Lab)
Tumblr allows users to report any issues “could jeopardize users’ blogs, expose their personal information, or allow any other nefarious activity to occur.” (Kaspersky Lab)
This could include simply posting an accidental post or unknowingly clicking a phishing link. Tumblr also contains adult content or as known on tumblr ‘nsfw’ content which an user can accidently access if clicked on a wrong tag. This also includes not paying attention to your Tumblr. Leaving your profile not monitored could lead to infecting with a virus which t hen could be spread to your friends list. (usecure)
Pay attention. Be careful with what you post and what you open. If you do open a link by accident and something unexpected started happening, run your anti-virus to check if a virus wasn’t downloaded onto your device. Tumblr also offers a set of settings that can help stay secure or block certain types of posts. (usecure)

IMO, being an all new continent and all, the game should take place pre or post-xen (storywise before or after the fall of the evil witch or even jeloc, however you wana figure) and the name should somehow encompass the current situation of the land and players.

java.lang.Object ch.epfl.lis.gnw.RegulatoryModule
public class RegulatoryModule
A HillGene is independently regulated by one ore more regulatory modules. A module is either an enhancer or a repressor (defined by isEnhancer_). The module is controlled synergistically by its activators, it is active only if all of them are bound together. Optionally, it can have deactivators, which synergistically silence the module. Note that the activators of a repressor module are actually repressors of the gene.

Validate all untrusted input using whitelist/positive input validation. Whitelist input validation allows only input that is explicitly defined as valid, as opposed to blacklist input validation, which filters out known bad input. Identify all types of input handled by the application and determine the valid format for each type, then add checks in code to make sure the data is valid before processing it.
Properly implemented input validation mitigates many types of injection vulnerabilities, such as Cross-Site Scripting and SQL injection. For native code applications, input validation can also mitigate memory management issues, such as Buffer Overflows.
To validate all untrusted input using whitelist input validation:
Identify all entry points for untrusted input. Make a list of all possible sources of untrusted input in your application. For a web application, this includes: form fields, request parameters, cookies, headers, files and databases. For a rich client or a mobile application, this includes: keyboard input, files, databases and network connections.
Identify all types of input accepted by the application. For each source of untrusted input on the list, define valid characters, length, format, and range (for numerical values).
Define an input validation subsystem. Define a set of validator functions to validate each type of input handled by the application. Input has to be validated on the server for client-server applications; it can be validated on the client-side as well, but not instead of on the server.
(All input) Validate length. Add code to all validators to check that the length of the untrusted input is valid. Checking length before using regular expressions helps prevent regular expression Denial-of-Service attacks.
(Text input) Validate characters. Add code to validators that handle text input to restrict the acceptable range of characters in text input using regular expressions.
(Structured input) Validate format. For validators that handle input that has a specific pattern, such as a date or a phone number, use regular expressions to make sure untrusted input matches the input type specified by the application.
(Numeric input) Validate range. For validators for numeric input, add code to restrict the acceptable range of numerical input by comparing the input to the maximum and minimum acceptable values.
(Optional) Reject and respond to known bad input. This step does not add much actual security, but it might provide defense in depth. The input validation subsystem can check for known attack strings and respond to these likely attacks by doing things like logging detailed attacker information, alerting the administrator, blocking the attacker's IP address for some time, and displaying an error message to the attacker.
(Context-sensitive) Encode input. If the input is going to be displayed back through a web browser, consider encoding it to prevent Cross-Site Scripting attacks before processing or storing it. Be careful not to introduce double-encoding issues by encoding this data again elsewhere in the code.

Park Hang-seo unveils 2-year plan for Vietnam football
Head coach Park hang-seo has revealed to South Korea’s Chosun Ilbo newspaper his plan for Vietnam national football team in the next two years.
by Thể thao 247, https://www.facebook.com/thethao247.vnAfter the goalless draw to Thailand on Tuesday, Park has his job done well with team Vietnam in 2019. His last task will be conquering the gold medal in SEA Games for U22 Vietnam.
This year has been a success for coach Park and the national team. Following a series of impressive achievements in the 2019 Asian Cup and the 2022 World Cup qualifiers, Park signed a new contract, continuing to work for Vietnamese football for at least 2 more years.
Park Hang-seo recently told the Chosun Ilbo: “The national team have accomplished thair tasks for 2019. I must go to Ho Chi Minh city to lead Team U22. We have had a wonderful year. I had good players and staff. I hope we will continue to move on with good luck next year.”
“Many have given me advices, of course. I have consulted with many. Some asked me why I don’t stop. Others encourage me to keep up the good work."
Asked about his contract extension, Park replied:
“I'm very grateful to this place where I want to be. Vietnam is a country that has given me a chance in my life. I am loved by the locals. Some people are worried about high expectations. If you are afraid of it, you can't do anything. I don't know what will happen in the future. But I feel that this is the right decision.”
In the exclusive interview with the Chosun Ilbo, Park reveals his 2-year plan for Vietnam national team: “There is no change in our lineup until next year. The lineup has been verified and we will decide whether to continue with it or not. The tactics must be replenished, indeed.”
>>> BREAKING: Park Hang-seo decides 2 over 22-year old players for SEA Games
“Next year, the young players can be upgraded to the senior team. The problem is that our central strikers lack experience. So I might make some changes, although we got used to the 5-4-1 formation when we faced stronger rivals.”
“I'm worried about how to manage the players. I need the assistance of nutritionists, medical teams, analysts, and physical coaches. I need as much help as possible. My plan is changing little by little,” Park said.
Park Hang-seo and U22 Vietnam will travel to the Philippines tomorrow. They will have two days to prepare for the match against Brunei in Group B.

Foreigners and Disease
Page 2 of 2
The collection also includes two rare prints depicting the foreign residents of
Nagasaki. The first, an anonymous print dating to ca. 1800, features a pair of Dutch
gentlemen seated at a cloth-covered table, which appears to be a sea chest in
disguise. The artist records with precision the novel appearance of these foreign men:
the black topcoat and ruffled jabot, wavy hair curling under a tall hat, the long, straight
nose.
Seated in a wooden chair, a contrivance not found in most Japanese homes at that
time, the man writes with a quill pen (not a brush!), moving from left to right in the
Western fashion. The man opposite him holds a circular disk in one hand, with marks at
the edges like a cracker or pastry. Baked goods were as exotic as the men and their
costumes, in a culture without ovens or bread.
It is likely that in making this image of foreigners at work, the artist relied on
illustrations and engravings from the West for inspiration. Ironically, though there was
clearly a demand for images of Nagasaki's foreign residents, few artists seem to have had
the opportunity to observe them at first hand.
A second image of Nagasaki residents, dating to the 1850s, clearly reflects this
paradoxical situation. In this case, the scene portrays two men in the company of
a Japanese woman, one of the geisha, or female entertainers, employed in the Maruyama
pleasure quarter in Nagasaki. The restaurant where the three are seated is drawn in
Western-style perspective, the architectural lines converging toward the horizon. The fine
line technique and cross-hatching used to shade the man's costume indicate that this is an
engraving, rather than a woodblock print, making the medium itself a Western import.
In addition to the foreign dress worn by the two men, another novelty, a long
spyglass, is held by one, pointing to the vista of Nagasaki harbor and sailing ships spread
out below the veranda. The sign with its Western lettering, the elaborate chandelier, and
wine glass visible on the table — all are elements emphasizing the sensational novelty to
be encountered on a visit to the Maruyama district.
In 1853, the arrival of Commodore Matthew Perry with his fleet of American
naval ships signaled the end of Japan's long isolation. In 1854, treaties were concluded
between Japan and the "five nations" — America, England, Russia, Holland, and France
— a new foreign community was established at Yokohama, less than twenty miles south
of Tokyo. From the early years of the Yokohama settlement, a host of prints were
created to record the appearance of the newest arrivals to Japan's shores.
Like the prints of Westerners in Nagasaki, these images confer a certain degree of
respect on the foreigners and their customs — playing down the potentially fearful
aspects of something unknown and possibly threatening. These images tend to focus on
ordinary activities about which the Japanese population might be curious: people eating
and drinking, smoking pipes, playing music, or writing.
Foreign women, prohibited from living at Dejima, are represented in many
images from this time, such as this fanciful depiction of a California port, dating to 1862. The closely observed details of the women's costumes, including fancy hats and
lacy mantillas, are, like the buildings and ship that crowd the horizon, likely copied
directly from Western newspaper illustrations. Two favorite sources were the London
Illustrated News and the American Frank Leslie's Illustrated Newspaper.
