increase the effectiveness of project management through standardized norms and practices across a range of project types. Thus, it exerts a strong influence on both how projects are conceptualized across a diverse range of disciplines and project types, and also on the sorts of training and education, and practitioner development that are seen as 'necessary' and appropriate for project managers.

-
Assumptions (about communications or otherwise) underlying the PMBOK are rarely explicit.
- The underlying assumptions are that projects are linear, rational, and deterministic
- ([42] Winter, M., Smith, C., Morris, P. and Cicmil, S. “Directions for Future Research in Project Management: The Main Findings of a UK Government Funded Research Network”, International Journal of Project Management 24, 2006, pp.638-649.)
- The linear, rational, deterministic 'attitude,' so to speak, is typical of a transmissional/representational view??
- "Managing communications" - Sender intentions vs. receiver expectations is a theme I see come up a lot, not always explicitly
- p.4316
- "One must question the efficacy of the view promoted in the PMBOK and enshrined in common 'n-step' [8] goal-directed project management menthods."
- p.4 (4318)
- PMBOK offers very little advice about communication - only really suggests breaking communication into "manageable, predictable, and orderly" steps (and more to the point, linear steps). Human communication is decidedly not linear.
- Implies that, if followed precisely, the planning and action steps prescribed by PMBOK will "naturally" result in good communication practices.
- What does 'actuality' mean?
- Schramm [36] - Shannon-Weaver model doesn't account for the role of social-contexts and "shared field of experience" in human communication
- cross-reference with "use existing social structures" from "experimental modes"??
-
furthermore, S-W model doesn't account for meaning-making (Bowman and Targowski [3]) nor does it consider the impacts of sender/receiver worldviews, experience, or how the act of interpretation shapes meaning.
- cross-reference with Wittgenstein/Schatzki - practical understanding, rule-interpretation, which are shaped by upbringing and experience, shape meaning and practices.
-
p.5 (4319)
- Bottom line is that, even if S-W and PMBOK offer some helpful suggestions for successful communication, the underlying assumptions don't provide adequate basis for developing the types of communication processes that are needed for successful IT PM.
- What is required for successful comm in IT PM situations??
- Success = delivery of product AND business value
- S-W, conduit, or transmission model focuses on information flows, doesn't take into account context, content, intention, interpretation, meaning [17].
- 4.2 - Galle's model [12]
- In order for IT projects to be successful, communication processes must include both production and interpretation of ideas amongst stakeholders, and are supported by artefacts [sic]
- what do they mean by artefact? see page 6 - artefact = product
- see red highlighting + comment: This is problematic - seems to invoke picture theory of language, which Wittgenstein ultimately showed to be an incomplete understanding - must an idea, concept, or whatever begin as a mental construct??
-
the solution suggested by Galle is that there is an interactive and iterative communication process through which various parties arrive at shared meaning - construe as a set of practices involving discourse through which meaning is derived - ex. group design in lean UX??
-
p.6 (4320)
- "The final project outcomes, both an IT artefact [sic] (product) and the delivery of value for key stakeholders, will only occur successfully if there are no substantial breakdowns in the sequence of productive and interpretive iterative, social interactions that occur amongst key players in the IT project context."
- Bottom line for Galle is that communication is a social process...Duh?
- "the glue between productive and interpretive activities, for Galle, is communication both verbal and non-verbal, which is mediated by artefacts produced along the way."
- However, Galle doesn't really provide insight into the "contextual nature of meaning and understanding."
- In other words, Galle doesn't directly account for the role of the different social and cultural backgrounds that individuals bring to an IT project situation, which shapes interpretation and understanding. The social, cultural, historical backgrounds shape how individuals and groups generate and maintain practices, and these can clash with the practices of those from different backgrounds.
- social, cultural, etc. background doesn't only refer to what we typically think of as upbringing - i.e. what is culturally inclulcated from birth - but also includes post-childhood, post-primary training and education (which are of course also shaped by social and cultural context). This education and training is especially relevant in IT project situations.
- The gaps in communication that can result from failure to take this into account are addressed by Wittgenstein's concept of language games.
-
4.2 - Language games [44]
- "Communication is composed of a multiplicity of language games in which meanings are constructed and understood by actors in specific contexts."
- "...the meanings of words are not simply denoted by the things they refer to...reference not establish meaning but [instead] relies on meaning and understanding."
- language and communication are not just concerned with words and meanings, they necesarily also include the individuals and groups whose experiences, backgrounds, and interactions shape words and meanings. Meaning is always context dependant, which explains how different groups within the same organization can develop communication practices that differ from other groups in the same organization. (they differ but can also be related, similar, mutually intelligeable, etc. via family resemblance).
- Language games are subject to rules that have been "learned in context" i.e. culturally, socially instilled.
- this is actually crucial for communication to work at all - communicating parties from different backgrounds nonetheless must have some shared understandings if they are to successfully communicate
- parties from from different backgrounds utilize these commonalities to realign their specific context-dependant communication practices in order to facilitate communication.
- "Communication exchanges are goal-directed, purposeful and generally intentional"
-
p.8 (4322)
- look up Vann [41] - regarding problem of IT project failure in public sector
- in this situation, myriad cultural, social, and linguistic "clashes" are possible as many different groups may have to interact: career public servants and other bureaucrats used to a particular way of operating, IT professionals/other technical types, government employees...really anyone can become entrenched and "stuck" in a particular language game.
- It is the job of the PM to bridge these divides - and TCs are uniquely situated because they must often move in and out of multiple contexts, and may have technical skills/knowledge but also the ability to sympathize and thus teach and communicate with less technically skilled individuals.


{{ block title }} Lottory {{ endblock }} {{ block content }}
Participants are required to play the 4 tables labelled, (table1a – table 2a) and (table 1b – table 2b). Each table has 6 decisions and combined make 24 decisions. Each table has an Option A (Lottery value package) and an Option B (Sure value). Compare the Lottery value package (Option A) with each value of the Sure value in (Option B). This means that in TABLE 1a for example, looking at Option B there are 6 Sure Values that are guaranteed incentives (R50, R60, R70, R80, R90 and R100). In column Option B, compare EACH Sure Value with the Lottery Value Package in Option A (R120 with 25% probability and R40 with 75% probability). For example; compare the R50 in Option B with the R120 with 25% probability & R40 with 75% probability in Option A. Would you rather get the R50 or get ONE of the Lottery Value in Option A. Make your decision in 'Decision 1'. If you choose the sure value of R50, tick 'Option B' in Decision 1. If you choose the lottery value package (R120 with 25% probability and R40 with 75% probability), tick 'Option A' in Decision 1. Do this in every decision. Tick a box to make your preferred choice of either Option A (Lottery value package) or Option B (Sure value). Do this in all 4 tables.

What is grid based design?
This is a framework consisting of rows and columns that I believe makes you code a lot cleaner to read and manage. This splits your web page into grids to enclose different elements as you wish, making the page look much more beautiful.
Whats all the hype about responsive webpages?
Responsive webpages are great! Through the use of code rules, you are able to maniplate the webpage depending on the type of device or size of screen used to view the page. It is very popular as there is an ever ending development of new devices, thus web pages must keep up with catering to them.
What is semantic structure?
Semantic sturcture is the way in which HTML is written so the user and browser can read it. It is structuring the content of a web page using HTML tags such as Header, Footer etc establishing order on the page.

England in New Zealand: Jos Buttler hits century as tourists draw final warm-up
| Tour match, Cobham Oval, Whangarei (day three of three): |
|---|
| New Zealand XI 302-6dec & 169-8: Archer 3-34, Curran 3-42 |
| England 405: Buttler 110, Pope 88, Denly 68; Kuggeleijn 3-46 |
| Match drawn |
| Scorecard |
Jos Buttler hit a century but England were unable to force victory in their final warm-up match against New Zealand A in Whangarei.
Resuming on 88 on day three, Buttler made 110 to help his side post 405 in reply to the hosts' 302-6 declared.
Jofra Archer and Sam Curran took three wickets each to reduce New Zealand A to 129-8, a lead of just 26.
But William Somerville and Ajaz Patel held firm for 22.4 overs to guide their side to 169-8 and ensure the draw.
England face New Zealand in two Tests, with the first match at the Bay Oval in Tauranga starting on Wednesday.
"It was really nice for me. Spending that time in the middle going into a Test series is great. It gives you confidence," Buttler told the BBC's Test Match Special.
"It's not a massive coincidence that when I've had time away from cricket and been able to refresh that I play well then.
"New Zealand will be a massive challenge. They are an excellent side and it should be a really exciting series."
Buttler, Ollie Pope (88) and Joe Denly (68) led England's recovery from 105-5 on day two at the Cobham Oval, as the tourists reached 355-8 at the close, a lead of 53.
Wicketkeeper Buttler put on 71 for the ninth wicket with Archer (41 not out) as he brought up his sixth first-class hundred - only his second in the past five years.
He finally fell after gloving a pull stroke off Scott Kuggeleijn behind to wicketkeeper Tom Blundell.
Kuggeleijn, who was drafted into the New Zealand A side on day two after Hamish Rutherford failed a concussion test, then removed Stuart Broad for a duck with the next ball to end the innings, giving England a lead of 103.
With Rutherford out after being struck by Archer on day one, Tim Seifert was promoted to open - but he lasted just two balls before nicking Archer to Dom Sibley at third slip.
Archer's pace troubled the batsmen on an otherwise docile pitch and the fast bowler also had opener Rachin Ravindra and Blundell caught by Sibley as the hosts fell to 99-6.
This side is set to start the first Test and Surrey left-armer Curran backed up the decision to play him instead of Chris Woakes by having Glenn Phillips and Jimmy Neesham caught behind, before bowling Kuggeleijn.
Broad and Ben Stokes took one wicket each as England looked to close in on victory, but they could not remove Somerville (32 not out) and Patel (10 not out) and captains Joe Root and Blundell shook hands on a draw with just under an hour of play remaining.

MapReduce Views Using the Java SDK with Couchbase Server
You can use MapReduce views to create queryable indexes in Couchbase Server.
The normal CRUD methods allow you to look up a document by its ID. A MapReduce (view query) allows you to look up one or more documents based on various criteria. MapReduce views are comprised of a map function that is executed once per document (this is done incrementally, so this is not run each time you query the view) and an optional reduce function that performs aggregation on the results of the map function. The map and reduce functions are stored on the server and written in JavaScript.
MapReduce queries can be further customized during query time to allow only a subset (or range) of the data to be returned.
| See the 6.0@server:learn:views/views-writing.adoc and 6.0@server:learn:views/views-querying.adoc sections of the general documentation to learn more about views and their architecture. |
The following example is the definition of a by_name
view in a "beer" design document.
This view checks whether a document is a beer and has a name.
If it does, it emits the beer’s name into the index.
This view allows beers to be queried for by name.
For example, it’s now possible to ask the question "What beers start with A?"
function (doc, meta) {
if (doc.type && doc.type == "beer" && doc.name) {
emit(doc.name, null);
}
}
A Spatial View can instead be queried with a range
or bounding box.
For example, let’s imagine we have stored landmarks with coordinates for their home city (eg.
Paris, Vienna, Berlin and New York) under geo
, and each city’s coordinates is represented as two attributes, lon
and lat
.
The following spatial view map function could be used to find landmarks within Europe, as a "by_location" view in a "spatial" design document:
function (doc, meta) {
if (doc.type && doc.type == "landmark" && doc.geo) {
emit([doc.geo.lon, doc.geo.lat], null);
}
}
Querying Views through the Java SDK
Query a view through the Java client through the query(ViewQuery q)
method on the Bucket
class.
This method returns a ViewResult
whose iterator yields the results of the query (in the form of ViewRow
objects).
The ViewResult
also exposes the list of rows (allRows()
), the success()
status and potential error()
.
The ViewRow
object contains the key
and value
properties (which are the first and second arguments to the view’s emit()
function, respectively) as well as the id
property, which may be passed to the get()
method to return the actual document.
Alternatively, directly call the document()
method on the view row.
Bucket bkt = CouchbaseCluster.create("<IP_ADDRESS>").openBucket("beer-sample");
ViewResult result = bkt.query(ViewQuery.from("beer", "by_name");
for (ViewRow row : result) {
System.out.println(row); //prints the row
System.out.println(row.document().content()); //retrieves the doc and prints content
}
You can also set various properties on the query:
Bucket bkt = CouchbaseCluster.create("<IP_ADDRESS>").openBucket("beer-sample");
ViewQuery q = ViewQuery.from("beer", "by_name")
.limit(5) // Limit to 5 results
.startKey("A")
.endKey("A\u0fff");
ViewResult result = bkt.query(q);
for (ViewRow row : result) {
System.out.println(row);
}
Here’s some sample output for the previous query:
DefaultViewRow{id=harvey_son_lewes-a_lecoq_imperial_extra_double_stout_1999, key=A. LeCoq Imperial Extra Double Stout 1999, value=null} DefaultViewRow{id=harvey_son_lewes-a_lecoq_imperial_extra_double_stout_2000, key=A. LeCoq Imperial Extra Double Stout 2000, value=null} DefaultViewRow{id=mickey_finn_s_brewery-abana_amber_ale, key=Abana Amber Ale, value=null} DefaultViewRow{id=brasserie_lefebvre-abbaye_de_floreffe_double, key=Abbaye de Floreffe Double, value=null} DefaultViewRow{id=brasserie_de_brunehaut-abbaye_de_saint_martin_blonde, key=Abbaye de Saint-Martin Blonde, value=null}

Querying Geospatial Views
To query a geospatial view, you will need to construct a SpatialViewQuery
object (com.couchbase.client.java.view.SpatialViewQuery
).
Spatial queries accept a startRange
and an endRange
parameter which allow you to limit the enclosing bounding boxes of the result.
The arguments to these parameters are JsonArray
with each element corresponding to a component emitted by the key (the first two components implicitly being the longitude and latitude of the result itself).
On output, spatial queries yield instances of SpatialViewRow
classes.
A SpatialViewRow
is similar to a ViewRow
, with an added geometry
property.
SpatialViewQuery q = SpatialViewQuery.from("spatial", "by_location")
.startRange(JsonArray.from(0, -90, null))
.endRange(JsonArray.from(180, 90, null));
SpatialViewResult result = bkt.query(q);
for (SpatialViewRow row : result) {
System.out.println("Key:" + row.key());
System.out.println("Value:" + row.value());
System.out.println("Geometry:" + row.geometry());
}
SpatialView
also has the includeDocs()
parameter to preload the document for the SpatialViewRow
's document()
method.
View results details
For all types of views, a ViewResult
is always returned, which contains zero to many ViewRows
.
In addition to iterative row access, more methods are available on the result:
| Method | Description |
|---|---|
|
Accumulates all returned rows in a List and returns it. |
|
Provides iterative access to rows as they arrive. |
|
The total number of rows in the index can be greater than the number of |
|
True if the query was successful, false otherwise.
Check |
|
Contains the error if the query was not successful or null otherwise. |
|
Contains debug information if |
The only difference between regular and spatial view results is the fact that spatial ones do not expose the number of totalRows
.
ViewQuery API details
All options shown here are available on the ViewQuery
in a fluent API manner.
All of them are optional, so only when they are explicitly provided, they will alter the behavior of the query.
As a general note, all arguments that accept JSON are provided with a higher number of method overloads to accommodate all combinations in a type-safe manner.

Here is how to use the range
parameter to find documents with a location within a bounding box.
We have stored cities Paris, Vienna, Berlin and New York.
Each city’s coordinates is represented as two attributes, lon
and lat
.
The spatial view’s map function is:
function (doc) { if (doc.type == "city") { emit([doc.lon, doc.lat], null); } }
To query the view and find cities within Europe, we use Europe’s bouding box. The startRange is the most south-western point of the bounding box, the endRange is its most north-eastern point:
JsonArray EUROPE_SOUTH_WEST = JsonArray.from(-10.8, 36.59);
JsonArray EUROPE_NORTH_EAST = JsonArray.from(31.6, 70.67);
SpatialViewResult result = bucket.query(SpatialViewQuery.from("cities", "by_location")
.stale(Stale.FALSE)
.range(EUROPE_SOUTH_WEST, EUROPE_NORTH_EAST));
List<SpatialViewRow> allRows = result.allRows();
for (SpatialViewRow row : allRows) {
System.out.println(row.id());
}
//prints:
//city::Vienna
//city::Berlin
//city::Paris
Retry Conditions
SDK retries view requests automatically on certain known conditions, which represented in the following table:
| HTTP status code | Behavior |
|---|---|
200 |
Do not retry request. |
300, 301, 302, 303, 307, 401, 408, 409, 412, 416, 417, 501, 502, 503, 504 |
Retry request. |
404 |
In case the library detects yet unprovisioned node, it will retry.
Otherwise, it will report |
500 |
If the error payload reports missing view document or badly formed query, it will not retry. Otherwise, it will retry request. |
All codes not listed in the table will not be retried by default. But the client code still can use retrying framework or write a custom handler. In the example below, it will retry 10 times if the view does not exist:
bucket.query(SpatialViewQuery.from("spatial", "test"))
.retryWhen(
RetryBuilder.anyOf(ViewDoesNotExistException.class)
.delay(Delay.exponential(TimeUnit.SECONDS, 1))
.max(10)
.build())
.subscribe(new Action1<AsyncSpatialViewResult>() {
@Override
public void call(AsyncSpatialViewResult result) {
// handle result
}
});

It’s been almost 3 years since I joined Young Minho Enterprise. Back then, in 2013, I had just arrived at Minho University in order to learn Software Engineering. Truth be told, I had absolutely no idea what my degree was all about. In fact, I had neither programmed nor knew what it was like. However, it was a sweet surprise when I understood what I would be doing for at least the next three years. I could go on about why I chose Software Engineering in the first place, but that is off the point. …
Making a template my own
As I was structuring my website, I came upon many Jekyll templates, some of which I forked. One of them, was Will Koehler’s a simplistic, intuitive but most importantly neatly coded. In fact, he refactored one of the blogs in Jekyll’s list, and wrote a post about what he did. …
Hello, world!
Yo! Welcome to my website, as you can see, and despite my initial doubts, it became a blog. So through this post I mean to cover the reasoning behind this webpage, my goals, fears and what I have in mind for the future. But first things first. Why did I start this? Although, I tried to do a plain single paged website about myself, I found that I was not able to capture what I was all about. This might sound quite peculiar, even more so knowing that I was never a fan of blogging, but I understood I had...…
Worse than ever
Building on Will Koehler’s post, I’ve taken the long way. By that, I mean I chose to personalise my blog, after all it’s an opportunity to get to know not only Jekyll, but also SEO and Javascript, it is where I intend to test out new things. So, after kinda like a robot myself, I settled on the amazing HMFAYSAL Omega Theme yet, despite the amazing design, which I could never reach by myself, the code seemed messier than my own. Though thanks to that, I get to refactor a project! …

This is a small module that provides an error page with helpful debugging information on it. The most useful part is that it tracks down the probable cause of the error and shows you a snippet of the file with the likely cause highlighted. As such, it should be used in development only and turned off for production mode.
The page is heavily inspired by the v1.0 Play Framework. In fact, the error page template is the one that the Play Framework used, with some modifications for Express.
Basically, it’s an alpha. Not tests yet. I’d love your help in making them. :)

Haystack supports two different methods of highlighting. You can either use SearchQuerySet.highlight or the built-in {% highlight %} template tag, which uses the Highlighter class. Each approach has advantages and disadvantages you need to weigh when deciding which to use.
If you want portable, flexible, decently fast code, the {% highlight %} template tag (or manually using the underlying Highlighter class) is the way to go. On the other hand, if you care more about speed and will only ever be using one backend, SearchQuerySet.highlight may suit your needs better.
Use of SearchQuerySet.highlight is documented in the SearchQuerySet API documentation and the {% highlight %} tag is covered in the Template Tags documentation, so the rest of this material will cover the Highlighter implementation.
The Highlighter class is a pure-Python implementation included with Haystack that’s designed for flexibility. If you use the {% highlight %} template tag, you’ll be automatically using this class. You can also use it manually in your code. For example:
>>> from haystack.utils import Highlighter
>>> my_text = 'This is a sample block that would be more meaningful in real life.'
>>> my_query = 'block meaningful'
>>> highlight = Highlighter(my_query)
>>> highlight.highlight(my_text)
u'...block that would be more meaningful in real life.'
The default implementation takes three optional kwargs: html_tag, css_class and max_length. These allow for basic customizations to the output, like so:
>>> from haystack.utils import Highlighter
>>> my_text = 'This is a sample block that would be more meaningful in real life.'
>>> my_query = 'block meaningful'
>>> highlight = Highlighter(my_query, html_tag='div', css_class='found', max_length=35)
>>> highlight.highlight(my_text)
u'...
block
 that would be more
meaningful
...'
Further, if this implementation doesn’t suit your needs, you can define your own custom highlighter class. As long as it implements the API you’ve just seen, it can highlight however you choose. For example:
# In ``myapp/utils.py``...
from haystack.utils import Highlighter
class BorkHighlighter(Highlighter):
def render_html(self, highlight_locations=None, start_offset=None, end_offset=None):
highlighted_chunk = self.text_block[start_offset:end_offset]
for word in self.query_words:
highlighted_chunk = highlighted_chunk.replace(word, 'Bork!')
return highlighted_chunk
Then set the HAYSTACK_CUSTOM_HIGHLIGHTER setting to myapp.utils.BorkHighlighter. Usage would then look like:
>>> highlight = BorkHighlighter(my_query)
>>> highlight.highlight(my_text)
u'Bork! that would be more Bork! in real life.'
Now the {% highlight %} template tag will also use this highlighter.

--- layout: archive title: Zulip Chat Archive permalink: /stream/113488-general/topic/CNL.20and.20the.20Stack.20Project.html ---
I just watched @Thales talk from last week, on CNL and Formal Abstracts. I was wondering about the following question: would it be interesting to attempt to pre-process the Stacks Project into something that is readable by the CNL? Is it reasonable to think that this is possible? (cc people that might know more about this: @Peter Koepke @Jesse Michael Han)
One reason for suggesting the Stacks Project is that it is written in a very strict subset of LaTeX
See https://github.com/stacks/stacks-project/blob/master/documentation/rules from which I will quote the 4th line:
Avoid reading this document at all cost!
it would be interesting, and definitely easier than preprocessing a less uniform corpus like all math pages from e.g. Wikipedia
besides working in a small subset of LaTeX, the CNL parser only accepts certain canned phrases in a certain order, so some NLP will be required to align the informal text with CNL equivalents
Yup, I guess it won't be trivial. But for an informal text, the Stacks Project is written rather on the formal side of the spectrum.
That's another reason why I think it might be an interesting target.
A long time ago, I thought about a baby version of this problem. Together with @Josef Urban we tried to "linkify" the Stacks Project: whenever a concept was defined in SP, link back to it when it is used later. We used some very basic NLP, but nothing fancy. As far as I remember, the results were cute, but not impressive. Also: I had to write a PhD thesis, so I stopped working on it.
Unfortunately, I don't think I have any code left from that side project.
Stacks tags the term being defined in each definition too, which is helpful.
You mean with the pattern {\it some-word}
?
Right, its unfortunate they don't use a more descriptive macro, but I guess that's counter to the whole philosophy of a strict subset of latex
I don't expect that you'll find many false positive {\it ...}
patterns inside definition environments.
It is true that one definition environment might contain multiple definitions.
I have an even babier version of what you are talking about set up for my own notes (nothing fancy at all, just matching exact strings + pluralization) but it works passably, the main difficulties are stacked adjectives (complete separated noetherian scheme) and mathematics overloading (even stacks has normal subgroups and normal schemes) I'd imagine your NLP approach would deal with the latter quite well?
No, our NLP wasn't very NLP at all. IIRC we used something that Josef called "bag-of-words" and was some sort of statistical matching algorithm.
We didn't pair it with any typing information. So if you had Let $X$ be a scheme. ... blabla ... Hence $X$ is normal.
Then it wouldn't figure out that normal
meant scheme.normal
(if there was no occurence of the word scheme
within the closest 10 words).
In fact, if group
occured near by (for some reason), it would likely have a false match.
Ideally, we could get a version of the Ganesalingam–BL parser. But that seems socially impossible.
Yeah that would definitely be a boost, let me know if you ever try anything like this, this problem has been something I've wanted to try and do more on for a while.
Ideally, we could get a version of the Ganesalingam–BL parser. But that seems socially impossible.
I don't know anything about this parser. What does your second sentence mean?
Mohan Ganesalingam and TBL (yes, that TBL) have a parser that eats LaTeX and spits out some weakly typed abstract syntax tree.
But Mohan doesn't want to share the code.
Ask Tim Gowers for details.
Hi,
I got an e-mail ping from Johan's post.
The short 2015 paper about our poor-man's Stacks hyper-linker is in
https://cicm-conference.org/2015/CICM2015-wip.pdf (p. 19 - 23).
As for combining statistical parsing and typing, we have so far done
a couple of things in the inf2formal project :
Learning probabilistic grammars from the corpora and adding native
(HOL/Mizar) typing inside the probabilistic parsers (but also using
the type checking and ATP ex post). See:
https://doi.org/10.1007/978-3-319-66107-0_2
https://doi.org/10.1109/SYNASC.2017.00036 and the Flyspeck-trained
demo at http://grid01.ciirc.cvut.cz/~mptp/demo.ogv .
Trained supervised neural translation models on synthetic
Latex-Mizar corpus: http://arxiv.org/abs/1805.06502 .
Recently we have added unsupervised neural translation (so an aligned
corpus is not needed) - https://arxiv.org/pdf/1912.02636 and
combined the neural translation with type-checking. This is so far
done by a simple data-augmentation loop between the neural net and
the Mizar elaborator (Section 5.4 of the paper). The paper
also shows that it is so far much harder to go from ProofWiki
(informal) to Mizar. To do this for Stacks, it would be good to
have at least some parts of Stacks formalized (in Lean or
whatever). I believe this is happening (Kevin, Johan & Co.), so UMT
methods might probably be directly tried right now.
We have also started to play with neural text summarization for
e.g. conjecturing over Mizar and Stacks -
http://grid01.ciirc.cvut.cz/~mptp/AITP_2020_paper_21.pdf . Again
(unsurprisingly), Stacks looks quite a bit harder (at least for the
task we have chosen) than the nice and declarative Mizar ND proofs for
such tasks.
Obviously, these are just the beginnings - the future of
autoformalization is bright and unavoidable (the naysayers can bet
me - see IHP Challenge 3 at http://ai4reason.org/aichallenges.html ;-).

@Josef Urban Oooh, I had completely forgotten about that wip document :face_palm: Thanks for reminding me (-;

- In the battle, there are 6 knights arrange in cyclic order, each knight have health of 100.
- Each knight perform attack move on next knight between the range of 1 to 6 (just like dice of 1 to 6)
- The attack value is any random number.
- On attack health gets subtracted (eg; 100-6)
- If health of knight becomes 0 then out of the game, other continues battling.

Makes 16 brioche têtes
Dietary
Brioche à tête (or parisienne) is a brioche baked into a fluted round tin with a ball of dough placed on top to form the ‘head’, the tête. Great for brunch with a strong coffee.
Equipment and preparation: You will need 16 brioche moulds.
Put the flour, sugar, yeast, salt, milk and five eggs into a free-standing food mixer and mix, for about five minutes, to a smooth dough. If mixing by hand, this will take about eight minutes.
Add the butter to the dough and mix for a further five minutes in the mixer, or 10 minutes by hand. Put the dough into a bowl, cover and leave in the fridge overnight.
The dough should now be stiff and easily shaped. Cut the dough into 50g/1¾oz pieces and divide 45g/1½oz for the brioche bodies and 5g/¼oz for the brioche heads.
Using your hands, shape the dough pieces into balls. Put each large piece of dough into a brioche mould and push a smaller dough on top of each once. Leave the brioche in a warm place to rise for one hour.
Preheat the oven to 200C/400F/Gas 6. Brush the brioche with the egg wash and bake for 20 minutes, or until golden-brown.
Transfer to a wire rack to cool.

What does this say:


Exception Codes
Exception Codes are used by .NET function to signify an error, the following table lists the exception codes with a definition for each
|
Exception |
Remarks |
|
System. ServiceProcess. TimeoutException |
The TimeoutException class can specify a message to describe
the source of the exception. When a method throws this exception, the message
is usually "The timeout provided has expired and the operation has not
been completed." This class is used, for example, by the ServiceController
class's WaitForStatus
member. The operation that can throw the exception is a change of the
service's Status
property (for example, from Paused to ContinuePending). |
|
System. SystemException |
This class is provided as a means to differentiate
between exceptions defined by the system versus exceptions defined by
applications. SystemException does not provide information as to the
cause of the Exception.
In most scenarios, instances of this class should not be thrown. In cases
where this class is instantiated, a human-readable message describing the
error should be passed to the constructor. SystemException is thrown by the common language runtime
when errors occur that are nonfatal and recoverable by user programs. These
errors result from failed runtime check (such as an array out-of-bound
error), and can occur during the execution of any method. SystemException adds no new functionality to Exception. SystemException uses the HRESULT COR_E_SYSTEM,
that has the value 0x80131501. For a list of initial property values for an
instance of SystemException, see the SystemException
constructors. |
|
System. OutOfMemoryException |
The following Microsoft intermediate (MSIL)
instructions throw OutOfMemoryException: ·
box ·
newarr ·
newobj OutOfMemoryException uses the HRESULT COR_E_OUTOFMEMORY, which
has the value 0x8007000E. For a list of initial property values for an
instance of OutOfMemoryException, see the OutOfMemoryException
constructors. .NET Compact Framework - Windows CE .NET
Platform Note: The common
language runtime can throw the exception when memory is not adequate to
allocate for internal purposes or new managed objects. To avoid the
exception, avoid programming large methods that consume 64 or more kilobytes
of memory. |
|
System. StackOverflowException |
StackOverflowException is thrown for execution stack overflow errors,
typically in case of a very deep or unbounded recursion. The Localloc
Microsoft intermediate language (MSIL) instruction throws StackOverflowException. StackOverflowException uses the HRESULT COR_E_STACKOVERFLOW,
that has the value 0x800703E9. For a list of initial property values for an
instance of StackOverflowException, see the StackOverflowException
constructors. |
|
System. ExecutionEngineException |
Execution engine errors are fatal errors that
should never occur. Such errors occur mainly when the execution engine has
been corrupted or data is missing. The system can throw this exception at any
time. When possible, the system throws an exception that provides more
information than the ExecutionEngineException exception. Applications should not throw ExecutionEngineException. ExecutionEngineException uses the HRESULT COR_E_EXECUTIONENGINE,
which has the value 0x80131506. For a list of initial property values for an
instance of ExecutionEngineException, see the ExecutionEngineException
constructors. |
|
System. MemberAccessException |
Normally a compilation error is generated if the
code attempts to access a nonexistent member of a class. MissingMemberException is designed to handle cases where a field or a method is deleted or
renamed in one assembly and the change is not reflected in a second assembly.
At runtime, MissingMemberException will be thrown when the code in the second assembly attempts to access
the missing member in the first assembly. MissingMemberException is the base class for MissingFieldException
and MissingMethodException.
In general it is better to use one of the derived classes of MissingMemberException to more precisely indicate the exact
nature of the error. Throw a MissingMemberException if you are only interested in capturing
the general case of a missing member error. MissingMemberException uses the HRESULT COR_E_MISSINGMEMBER,
that has the value 0x80131512. For a list of initial property values for an instance
of MissingMemberException, see the MissingMemberException
constructors. |
|
System. ApplicationException |
ApplicationException is thrown by a user program, not by the
common language runtime. If you are designing an application that needs to
create its own exceptions, derive from the ApplicationException class. ApplicationException extends Exception,
but does not add new functionality. This exception is provided as means to
differentiate between exceptions defined by applications versus exceptions
defined by the system. ApplicationException does not provide information as to the
cause of the exception. In most scenarios, instances of this class should not
be thrown. In cases where this class is instantiated, a human-readable
message describing the error should be passed to the constructor. ApplicationException uses the HRESULT COR_E_APPLICATION, which
has the value 0x80131600. For a list of initial property values for an
instance of ApplicationException, see the ApplicationException constructors. |
|
System. AppDomainUnloadedException |
AppDomainUnloadedException uses the HRESULT COR_E_APPDOMAINUNLOADED,
which has the value 0x80131014. For a list of initial property values for an
instance of AppDomainUnloadedException, see the AppDomainUnloadedException
constructors. |
|
System. ArgumentException |
ArgumentException is thrown when a method is invoked and at
least one of the passed arguments does not meet the parameter specification
of the called method. All instances of ArgumentException should carry a meaningful error message
describing the invalid argument, as well as the expected range of values for
the argument. The primary derived classes of ArgumentException are ArgumentNullException
and ArgumentOutOfRangeException.
These derived classes should be used instead of ArgumentException, except in situations where neither of the
derived classes is acceptable. For example, exceptions should be thrown by:
If the method call does not have any argument or
if the failure does not involve the arguments themselves, then InvalidOperationException
should be used. ArgumentException uses the HRESULT COR_E_ARGUMENT, which has
the value 0x80070057. For a list of initial property values for an
instance of ArgumentException, see the ArgumentException constructors. |
|
System. ArgumentNullException |
ArgumentNullException is thrown when a method is invoked and at
least one of the passed arguments is a null reference (Nothing in Visual Basic) and should never be null. ArgumentNullException behaves identically to ArgumentException.
It is provided so that application code can differentiate between exceptions
caused by null arguments and exceptions caused by arguments that are not
null. For errors caused by arguments that are not null, see ArgumentOutOfRangeException. ArgumentNullException uses the HRESULT E_POINTER, which has the
value 0x80004003. For a list of initial property values for an
instance of ArgumentNullException, see the ArgumentNullException constructors. |
|
System. ArgumentOutOfRangeException |
ArgumentOutOfRangeException is thrown when a method is invoked and at
least one of the arguments passed to the method is not a null reference (Nothing in Visual Basic) and does not contain a
valid value. ArgumentOutOfRangeException is used extensively by: ·
Classes
in the System.Collections
and System.IO
namespaces. ·
The Array
class. ArgumentOutOfRangeException behaves identically to ArgumentException.
It is provided so that application code can differentiate between exceptions
caused by invalid arguments that are not a null reference (Nothing), and exceptions caused by null arguments.
For errors caused by null arguments, see ArgumentNullException. ArgumentOutOfRangeException uses the HRESULT COR_E_ARGUMENTOUTOFRANGE,
which has the value 0x80131502. For a list of initial property values for an
instance of ArgumentOutOfRangeException, see the ArgumentOutOfRangeException constructors. |
|
System. ArithmeticException |
ArithmeticException is the base class for DivideByZeroException,
NotFiniteNumberException,
and OverflowException.
In general, use one of the derived classes of ArithmeticException to more precisely indicate the exact
nature of the error. Throw an ArithmeticException if you are only interested in capturing a
general arithmetic error. ArithmeticException uses the HRESULT COR_E_ARITHMETIC, which
has the value 0x80070216. For a list of initial property values for an
instance of ArithmeticException, see the ArithmeticException constructors. |
|
System. ArrayTypeMismatchException |
ArrayTypeMismatchException is thrown when the system cannot convert
the element to the type declared for the array. For example, an element of
type String
cannot be stored in an Int32
array because conversion between these types is not supported. It is
generally unnecessary for applications to throw this exception. The following Microsoft intermediate language
(MSIL) instructions throw ArrayTypeMismatchException: ·
ldelem.<type>
·
ldelema
·
stelem.<type>
ArrayTypeMismatchException uses the HRESULT COR_E_ARRAYTYPEMISMATCH,
which has the value 0x80131503. For a list of initial property values for an
instance of ArrayTypeMismatchException, see the ArrayTypeMismatchException constructors. |
|
System. BadImageFormatException |
This exception is thrown when the file image of an
executable program is invalid. For example, this exception is thrown when
unmanaged code is passed to Load
for loading. BadImageFormatException uses the HRESULT COR_E_BADIMAGEFORMAT,
which has the value 0x8007000B. For a list of initial property values for an
instance of BadImageFormatException, see the BadImageFormatException constructors. |
|
System. CannotUnloadAppDomainException |
CannotUnloadAppDomainException is thrown when there is an attempt to
unload: ·
The
default application domain, which must remains loaded during the lifetime of
the application. ·
An
application domain with a running thread that cannot immediately stop
execution. ·
An
application domain that has already been unloaded. CannotUnloadAppDomainException uses the HRESULT
COR_E_CANNOTUNLOADAPPDOMAIN, which has the value 0x80131015. For a list of initial property values for an
instance of CannotUnloadAppDomainException, see the CannotUnloadAppDomainException
constructors. |
|
System. TypeUnloadedException |
TypeUnloadedException uses the HRESULT COR_E_TYPEUNLOADED,
that has the value 0x80131013. For a list of initial property values for an
instance of TypeUnloadedException, see the TypeUnloadedException
constructors. |
|
System. ContextMarshalException |
Objects can marshal by value or by reference. Any
attempt to pass a type that cannot be marshaled through a context boundary

These exceptions are thrown when a class member is not found or access to the
member is not permitted. MemberAccessException is thrown by the following methods: Invoke
of the System.Reflection
classes, GetValue
of the FieldInfo
class, and DynamicInvoke
of the Delegate
class. MemberAccessException uses the HRESULT COR_E_MEMBERACCESS,
that has the value 0x8013151A. For a list of initial property values for an
instance of MemberAccessException, see the MemberAccessException constructors. |
|
System. MissingMemberException |
Normally a compilation error is generated if the
code attempts to access a nonexistent member of a class. MissingMemberException is designed to handle cases where a field or a method is deleted or
renamed in one assembly and the change is not reflected in a second assembly.
At runtime, MissingMemberException will be thrown when the code in the second assembly attempts to access
the missing member in the first assembly. MissingMemberException is the base class for MissingFieldException
and MissingMethodException.
In general it is better to use one of the derived classes of MissingMemberException to more precisely indicate the exact
nature of the error. Throw a MissingMemberException if you are only interested in capturing
the general case of a missing member error. MissingMemberException uses the HRESULT COR_E_MISSINGMEMBER,
that has the value 0x80131512. For a list of initial property values for an
instance of MissingMemberException, see the MissingMemberException
constructors. |
|

reference (Nothing in Visual Basic). A combinable delegate
type must satisfy the following conditions: ·
The
declared return type of the delegate must be void. ·
None
of the parameters of the delegate type can be declared as output parameters. A multicast delegate instance is created by
combining two or more delegate instances that are not a null reference. For
more information, see MulticastDelegate. MulticastNotSupportedException uses the HRESULT COR_E_MULTICASTNOTSUPPORTED,
that has the value 0x80131514. For a list of initial property values for an
instance of MulticastNotSupportedException, see the MulticastNotSupportedException
constructors. |
|

values for an instance of NotImplementedException, see the NotImplementedException
constructors. |
|
System.NotSupportedException |
There are methods that are not supported in the
base class, with the expectation that these methods will be implemented in
the derived classes instead. The derived class might implement only a subset
of the methods from the base class, and throw NotSupportedException for the
unsupported methods. NotSupportedException is also thrown by System.IO
classes whenever there is an attempt to read, seek, or write to a stream that
does not support the invoked functionality. For scenarios where it is sometimes possible for
the object to perform the requested operation, and the object state
determines whether the operation can be performed, see InvalidOperationException. NotSupportedException uses the HRESULT COR_E_NOTSUPPORTED, which
has the value 0x80131515. For a list of initial property values for an
instance of NotSupportedException, see the NotSupportedException
constructors. |

·
conv.ovf.<to
type> ·
conv.ovf.<to
type>.un ·
mul.ovf.<type>
·
sub.ovf.<type>
·
newarr
For a result from an integral or decimal-type
arithmetic operation or conversion that is outside the range of the
destination type: ·
In a
checked context, a compile-time error occurs if the operation is a constant
expression. Otherwise, an OverflowException is thrown if the operation is performed at run-time. ·
In an
unchecked context, the result is truncated by discarding any high-order bits
that do not fit in the destination type. OverflowException uses the HRESULT COR_E_OVERFLOW,
that has the value 0x80131516. For a list of initial property values for an
instance of OverflowException, see the OverflowException

|
System. Threading. ThreadAbortException |
When a call is made to the Abort
method to destroy a thread, the common language runtime throws a ThreadAbortException. ThreadAbortException
is a special exception that can be caught, but it will automatically be
raised again at the end of the catch block. When this exception is raised, the runtime executes all the finally blocks before killing the thread. Since
the thread can do an unbounded computation in the finally blocks, you must call the Join
method to guarantee that the thread has died. Join is a blocking call that does not return
until the thread actually stops executing. ThreadAbortException uses the HRESULT COR_E_THREADABORTED,
which has the value 0x80131530. |
|
System. Threading. ThreadInterruptedException |
After a thread is created, it is in one or more ThreadState
states until it is destroyed. Calling Interrupt
when a thread is in the WaitSleepJoin
state will cause a ThreadInterruptedException to be thrown. ThreadInterruptedException uses the HRESULT COR_E_THREADINTERRUPTED,

the ThreadState
states until it terminates. ThreadStateException is thrown by methods that cannot perform
the requested operation due to the current state of a thread. For example,
trying to restart an aborted thread by calling Start
on a thread that has terminated throws a ThreadStateException. ThreadStateException uses the HRESULT COR_E_THREADSTATE, which
has the value 0x80131520. For a list of initial property values for an
instance of ThreadStateException, see the ThreadStateException
constructors. |
|
System. Reflection. AmbiguousMatchException |
AmbiguousMatchException uses the HRESULT COR_E_AMBIGUOUSMATCH
which has the value 0x8000211D. An AmbiguousMatchException is thrown if the application calls upon a class and it cannot
determine which class or overloaded class to utilize. The binding attempts to
locate the proper class to use, determined by the number of parameters and
the type of parameters. If multiple acceptable classes are located, AmbiguousMatchException is thrown. Overload
resolution is a mechanism for selecting the best function member to invoke
given an argument list and a set of candidate function members. Overload
resolution selects the function member to invoke. If a selection cannot be
determined, an AmbiguousMatchException is thrown. |
|
System. Reflection. CustomAttributeFormatException |
CustomAttributeFormatException uses the HRESULT COR_E_FORMAT which has
the value 0x80131537. CustomAttributeFormatException is thrown if a custom attribute on a data

instance of SerializationException, see the SerializationException
constructors. |
|
System. Resources. MissingManifestResourceException |
MissingManifestResourceException uses the HRESULT
COR_E_MISSINGMANIFESTRESOURCE which has the value 0x80131532. MissingManifestResourceException uses the default Equals
implementation, which supports reference equality. For a list of initial property values for an
instance of MissingManifestResourceException, see the MissingManifestResourceException
constructors. Note It is strongly
recommended that your main assembly contains a neutral set of resources, so
if a satellite assembly is unavailable, your application will have some
acceptable behavior. |
|

This
exception is typically thrown when the code requests more permissions than
the policy will grant or the policy is configured to prohibit running the
code. PolicyException uses the HRESULT
CORSEC_E_POLICY_EXCEPTION. For a
list of initial property values for an instance of PolicyException,
see the constructor. |
|
System. Runtime. InteropServices. ExternalException |
To enhance interoperability between legacy systems
and the common language runtime, the ErrorCode
property stores an integer value (HRESULT) that identifies the error. User
defined exceptions should never derive from ExternalException, and an ExternalException should never be thrown by user code. Use
the specific exceptions that derive from ExternalException instead. ExternalException uses the HRESULT E_FAIL which has the
value 0x80004005. ExternalException uses the default Equals
implementation, which supports reference equality. For a list of initial values for an instance of ExternalException, see the ExternalException constructors. |
|
System. Runtime. InteropServices. COMException |
The common language runtime transforms well-known
HRESULTs to .NET exceptions, enabling COM objects to return meaningful error
information to managed clients. The HRESULT to exception mapping also works
in the other direction by returning specific HRESULTs to unmanaged clients.
For mapping details, see HRESULTs
and Exceptions. When the runtime encounters an unfamiliar HRESULT
(an HRESULT that lacks a specific, corresponding exception), it throws an
instance of the COMException class. This all-purpose exception exposes the
same members as any exception, and includes a public ErrorCode property that contains the HRESULT
returned by the callee. If an error message is available to the runtime
(obtained from the IErrorInfo
interface or the Err object in
Visual Basic, or in some cases from the operating system), the message is
returned to the caller. However, if the COM component developer fails to
include an error message, the runtime returns the eight-digit HRESULT in
place of a message string. Having an HRESULT allows the caller to determine
the cause of the generic exception. Although you can use the COMException
class to return specific HRESULTs to unmanaged clients, throwing a specific
.NET exception is better than using a generic exception. Consider that
managed clients as well as unmanaged clients can use your .NET object, and
throwing an HRESULT to a managed caller is less comprehendible than throwing
an exception. |
|
System. Runtime. InteropServices. InvalidComObjectException |

|
System. IO. InternalBufferOverflowException |
In a FileSystemWatcher,
when you are notified of file changes, the system stores those changes in a
buffer the component creates and passes to the Application Programming
Interfaces (APIs). If there are many changes in a short time, the buffer can
easily overflow, resulting in an exception being thrown, which essentially
loses all changes. To keep the buffer from overflowing, use the FileSystemWatcher.NotifyFilter
and FileSystemWatcher.IncludeSubdirectories
properties to filter out your unwanted change notifications. You can also
increase the size of the internal buffer through the FileSystemWatcher.InternalBufferSize
property. However, increasing the size of the buffer is expensive, so keep
the buffer as small as possible. |

Detailed Description
Structure to hold VN-200 data.
Member Data Documentation
| float dfti::VN200Data::accelMps2[3] = {0} |
Accelerations.
Body-axis accelerations in m/s^2. Includes the effect of gravity and is bias compensated by the EKF. Order is Ax, Ay, Az.
| float dfti::VN200Data::angularRatesRPS[3] = {0} |
Angular Rates.
Stores the body-axis angular rates P, Q, and R in radians per second. Order is P, Q, R.
| float dfti::VN200Data::eulerDeg[3] = {0} |
Euler Angles.
Stores the 3-2-1 Euler angles psi, theta, phi in degrees. Order is yaw, pitch, roll.
| quint64 dfti::VN200Data::gpsTimeNs = 0 |
GPS time.
The GPS time is represented as the absolute number of nanoseconds from the GPS epoch, January 6, 1980 at 0000 UTC.
| double dfti::VN200Data::posDegDegM[3] = {0} |
Lat-Long-Alt Position.
Contains the latitude, longitude, and altitude position of the aircraft in inertial space. The lat/long are in degrees, and the altitude is in meters.
Order is lat, long, alt.
| float dfti::VN200Data::quaternion[4] = {0} |
Quaternion.
Stores the attitude quaternion giving the body frame with respect to the local North East Down frame.
Note that the VN-200 uses the last term as the scalar value in its output, but DFTI uses the first term as the scalar as is common.
| float dfti::VN200Data::velNedMps[3] = {0} |
NED Velocity.
Stores the estimated velocity in the North-East-Down frame in m/s. Order is Vx, Vy, Vz.
