Major sub-task reported by Mohammad Kamrul Islam and fixed by Mohammad Kamrul Islam
Timeline server is enabled by default
Since Timeline server is not matured and secured yet, enabling it by default might create some confusion.
We were playing with 2.4.0 and found a lot of exceptions for distributed shell example related to connection refused error. Btw, we didn't run TS because it is not secured yet.
Although it is possible to explicitly turn it off through yarn-site config. In my opinion, this extra change for this new service is not worthy at this point,.
This JIRA is to turn it off by default.
If there is an agreement, i can put a simple patch about this.

- YARN-1957.
Major sub-task reported by Carlo Curino and fixed by Carlo Curino (resourcemanager)
ProportionalCapacitPreemptionPolicy handling of corner cases...
The current version of ProportionalCapacityPreemptionPolicy should be improved to deal with the following two scenarios:
1) when rebalancing over-capacity allocations, it potentially preempts without considering the maxCapacity constraints of a queue (i.e., preempting possibly more than strictly necessary)
2) a zero capacity queue is preempted even if there is no demand (coherent with old use of zero-capacity to disabled queues)
The proposed patch fixes both issues, and introduce few new test cases.

Javascript injection on the job status page
Scripts can be injected into the job status page as the diagnostics field is
not sanitized. Whatever string you set there will show up to the jobs page as it is ... ie. if you put any script commands, they will be executed in the browser of the user who is opening the page.
We need escaping the diagnostic string in order to not run the scripts.

Private API change in YARN-1824 in 2.4 broke compatibility with previous releases

Test TestFSDownload.testDownloadPublicWithStatCache fails on Windows
The TestFSDownload.testDownloadPublicWithStatCache test in hadoop-yarn-common consistently fails on Windows environments.
The root cause is that the test checks for execute permission for all users on every ancestor of the target directory. In windows, by default, group "Everyone" has no permissions on any directory in the install drive. It's unreasonable to expect this test to pass and we should skip it on Windows.

Improve default paths of timeline store and generic history store
When I enable AHS via yarn.ahs.enabled, the app history is still not visible in AHS webUI. This is due to NullApplicationHistoryStore as yarn.resourcemanager.history-writer.class. It would be good to have just one key to enable basic functionality.
yarn.ahs.fs-history-store.uri uses {code}${hadoop.log.dir}{code}, which is local file system location. However, FileSystemApplicationHistoryStore uses DFS by default.

Ronin
Ronin sports one of the best car chases in recent memory. The chase (the film's third) has cars speed in and out of tunnels, in wrong directions on major highways, and through narrow, scenic pedestrian-littered streets. It conjures up memories of _The French Connection_, _To Live and Die in L.A._ and _Speed_ all at once, and further transcends them due to its distinctively Euro look. The ride is thrilling. The accidents are devastating. And yet, there's something so, so, plastic and nihilistic about the whole setup.
 Like _Fiction_, it sports an excellent diverse cast, each character with mixed motives. Robert DeNiro is the American, Jean Reno (_The Professional_, _Godzilla_) is the Frenchman, Stellan Skarsgard (_Breaking the Waves_, _Good Will Hunting_) is the German, and Natasha McElphone (_Truman Show_) is the mysterious Irish ringleader. The cast plays off each other with the standard personas each has been associated with.
The film even has a _Fiction_-esque McGuffin--a mysterious silver briefcase. "What's in the case?" asks DeNiro, repeatedly. Perhaps the mathematical "process" described in _The Spanish Prisoner_.
But, also like _PF_, there is such a casual disregard for human life that it is ultimately off-putting. What made _Pulp Fiction_ work and _Ronin_ less satisfactory is that _Pulp Fiction_ worked on a much smaller scale, with every death in that film being economic and significant in its storyline/shock value. _Ronin_ spends too much of its time shooting, crashing, and killing that it gives us no reason to care for its central characters. Or charicatures.
Back to that car chase. The camera captures the car running down a few pedestrians. Cut to: interior look of car, McElphone is unfazed. No dialogue. No fear of getting caught. Cut to: car no. 2, with Jean Reno in the driver's seat. Six cars crash right behind him, yet he keeps going, expressionless. The audience's adrenaline is pumping, but both characters and their passengers, are sedate. What gives?
This goes on for nearly ten minutes. The city is destroyed. Innocent bystanders die. Fifty cars get demolished. Yet very few police cars respond. (Were they on strike?) And the oncoming traffic seems incomprehensibly calm over the ensuing havoc. ( Did the traffic reports prepare them?)
I suppose we, as imbecillic movie patrons can watch that and think, "Wow, that's so cool." James Bond doesn't flinch, why should they? My take: for a film that is meant to be taken with a grain of salt, it has a devastating ancillary tone. It takes everything way too seriously, from its travellogue/historical settings, to its every-day-is-a-rainy-day cinematography, to the let's throw in every hard-to-understand accent we can find in its dialogue, to its wink-wink references of the CIA, KGB and (here's the clincher) IRA.
The final scene ruined it for me. Without spoiling the film, there is a scene terribly reminiscent of _Snake Eyes_, except, at least in _that_ film, the police acted somewhat responsibly, the crowds became involved with the crime, and, ultimately, justice was served. Here, a devastating threat is made, said threat is actually followed through, and... nothing comes of it. We see the victims, but the bad guy, at least that one particular bad guy whose face is concealed, gets away. Why waste our time? There's enough illogical madmen getting away with horrific crimes displayed on our nightly news.
So I could not care for the characters. Consequently, the story bored me. Hence, I cannot recommend this film. And yet... there _is_ that wonderful car chase. I'm torn.
Video, anyone?

Chase the stink out of your running clothes.
What is it about running clothes? They stink. And by now, after a great season of training for the Blue Cross Broad Street Run, your running gear is most likely...fragrant.
Oh sure, they might smell fine when you first pull them out of the dryer, but give them an hour and their super smell returns. Put them on, and you risk passing out. Why not save yourself the embarrassment and torture, and use this time during your recovery week to treat your clothes to some TLC.
Some suggestions for getting the stink out:
Wash clothes as quickly a possible after a run.
Pretreat clothes with detergent made for wool.
Add some baking soda and a little splash of hydrogen peroxide to your regular detergent and use a cold-water wash.
Use a detergent specially formulated for sports clothes:
Penguin Sport-Wash®, Win High Performance Sport Detergent, or SportSuds™.
If all else fails... buy some new clothes. You, and everyone running behind you, will thank you!
Happy trails!

- International organization Equality Now honoured Nigerian author Chimamanda Ngozi Adichie on Thursday, November 21
- Adiche was recognised for fighting gender inequality with her words
- English writer and activist, Scarlett Curtis was also honoured alongside Adiche
Prolific Nigerian author Chimamanda Adiche has been recognized alongside English writer and activist, Scarlett Curtis for fighting gender inequality with written words.
Both authors were honoured by international organization Equality Now on Thursday, November 21 at the annual Make Equality Reality Gala in New York City.
According to reports, the night was filled with art, advocacy, and entertainment to inspire activism, with an interactive musical number by the Resistance Revival Chorus, a satirical political sketch by Stacey Kramer, and a riveting spoken-word performance about sexual assault by Katie Capiello.
Adichie is the critically acclaimed author of five books, a MacArthur Genius Grant winner, and is even featured on Beyoncé’s hit song “Flawless.” While accepting th honour, Adiche stated that she was a feminist long before she knew what the word meant.

I want to focus on one of five subgoals. I do this using an inelegant combination of swap
s and sorry
s. Once I am there, at the heart of the matter, I realise that my context is gigantic; I don't think I'll be using add_left_neg
any more, for example.
Is there a command which just clears as much of the context as it is possible to do? I have come to an interesting sub-question and I want to see better what's going on.
/-- `clear h₁ ... hₙ` tries to clear each hypothesis `hᵢ` from the local context. -/ meta def clear : parse ident* → tactic unit := tactic.clear_lst
Can I use this tactic somehow? I don't speak meta.
I am getting sick of
clear tactic failed, hypothesis 'zero_add' depends on 'add_assoc'
holes
ha ha I've got an algorithm
clear right_distrib left_distrib add_comm add_zero add_assoc add,
found by switching view to the weird ctrl-shift-alt-enter "info view" which I never use, and then just clearing the first thing it complained about as well. This is getting through it nicely.
Feel free to use: https://github.com/avigad/qpf/blob/97befa73d34ed26137dbb991941d5ce1b1a3e794/src/for_mathlib.lean#L614-L618
show (zero_1 = zero), -- refl still fails clear add_left_neg, -- only 20 more to go clear zero_add, clear right_distrib left_distrib add_comm add_zero add_assoc add, clear neg, clear mul_one one_mul mul_assoc mul, clear one, clear add_zero_1 add_left_neg_1 zero_add_1 add_assoc_1 add_1, /- clear tactic failed, hypothesis 'add_left_neg_1' depends on 'add_zero_1' dammit my algo failed! -/ end
Dammit my algo just failed!
meta def clear_except (xs : parse ident *) : tactic unit := do let ns := name_set.of_list xs, local_context >>= mmap' (λ h : expr, when (¬ ns.contains h.local_pp_name) $ try $ tactic.clear h) ∘ list.reverse
Simon's tactic.
I don't understand a word of it, but let's give it a go
It doesn't delete all my files, does it?
As far as you know, no it doesn't
unknown identifier 'parse'
I'm not very good at meta
you have to spoonfeed me :-/
Give me a moment, I'll PR it
Just update mathlib to HEAD
Revision 9daa1a579fd86c537229c34a00a18a23fdad4db8
And now I have to compile mathlib manually, right?
You have given me an assembly manual for your new tool, and now I have to build it myself.
I've learnt a lot more about git recently. The perfectoid project has taught me a lot about teamwork.
:) yeah, unfortunately, being on the bleeding edge means you have to do more work yourself. You can also wait until it gets into the nightly build
I don't mind compiling. I am only just beginning to realise that it's much better for you to make a PR than it is to start posting code here. it's easier for both you and me.
you get a preliminary version up and running at your end, throw out a new branch and I can get it, compile, and test it. It's all just dawning on me really, how all this stuff works.
I find it really interesting how important it is to learning to write very large proofs to learn to just use the tools effectively
We're 11000 lines in and are running into technical issues with the typeclass system; debugging these instances is, for me, the best way of understanding them; it's better than just asking. I am finally learning to find my own way around Lean.
I like the idea of clear_except
, but it would be nice if it can be written clear - h1 h2
Are you suggesting we put it into core?
that or make a clear'
Actually maybe that's a thing we can do on the community fork now... update all the core tactics to match the primed versions
they should all be backward compatible afaik
I agree with the latest statement.
The thing with the clear - h
idea is: does clear h - h'
mean anything? Should it mean something?
the thing after clear is a list of names so it's not a problem
I was thinking only clear h1 h2
or clear - h1 h2
clear h - h'
doesn't really mean anything not expressible with one of the other two options
And if you want to clear everything, you write clear -
which I don't like
Maybe we could have a tactic called clear_all
and add options clear_all - h0 h1
btw this notation exactly matches the coq tactic iirc
what about clear * - h1 h2
?
also there is another predicate I can imagine saying which isn't expressible: clear everything except for x
and the hypotheses that depend on x
Oh, clear_except
works really well for me! Thank you Simon -- you are a master tool maker when it comes to things like this.
A tactic state with over 30 hypotheses became
A : Huber_pair, v : ↥(Spa A), zero zero_1 : ring_completion (valuation_field (out (v.val))) ⊢ zero_1 = zero
I cheated: I've been using it for over a year so I had some time to improve it

Obviously, proper input validation is crucial for an effective and sustained learning success. Because our website is based on Jekyll, however, we have to rely on client-side validation (relying on an external service for validation only is probably not reliable enough, so we decided against that approach). To this date, client-side validation (= Javascript) doesn't offer proper support for RelaxNG, the schema language ultimately used to validate MEI instances in real projects. For this reason, we need to use the XPath-based approach mentioned earlier.
The "xpaths"
property of the current step holds an array of rules to which the user's encoding must
conform in order to complete that step. These rules are specified as JSON objects with three properties:
{ "rule":"//mei:note/@pname = 'g'", "renderanyway":true, "hint":"You need a @pname attribute, with a value of g." }
The "rule"
property holds an XPath 1
expression, which must resolve to a boolean statement: it has to be
either true or false. The "renderanyway"
is used to decide if the current editor can be rendered by Verovio
even if the XPath isn't matched. The content of "hint"
is supposed to assist the user to reach the correct encoding. Only
the first failing XPath will be displayed at a time, guiding the
user step by step through the different requirements. However, not
every step needs a hint – sometimes it's better to let the user
explore a bit on his own.
For validation, the current user input will be inserted between the
<?snippet-start?>
and <?snippet-end?>
markers in the current XML file, and then the XPath rules will be
checked against that complete file. As soon as one of these rules fails
(i.e. returns false), the corresponding "hint"
will be displayed. When all rules return true, the "continue"
button will be enabled and the user may proceed to the next step.

--- layout: post esbma_id: 1194 title: Law #12: The Law of Line Extension date: 2004-06-16 14:52:51 keywords: law ---
(This entry is part of a series I am writing on The 22 Immutable Laws of Marketing.)
Ouch! Ralph Johnson says I am making "snide" comments about Java marketing. That stings.
Dr. Johnson was one of my professors at UIUC.  He's incredibly smart, and he would be a finalist in the Nicest Guy on Earth competition. When Dr. Johnson whispers, it sounds loud, at least to me.
Still, despite the small rebuke from my mentor, I can't quite bring myself to repent. I'm not trying to be mean or arrogant, but my goodness, we're talking about Sun here.
"Bummer of a birthmark, Hal"
Asking me not to be critical of Java marketing is like asking me to watch a Jim Carrey flick and only pay attention to the supporting cast. Some things are just too obvious to ignore.
It's fair to observe that everything is relative. Dr. Johnson is talking about Smalltalk marketing, and I suppose Java marketing looks pretty effective from that point of view. Clearly, Java is a big success. It is a mainstream language and platform. However, I remain of the opinion that Java could have been even more.
Remember: Marketing is an iceberg. There is the part of marketing you can see (advertising and communications), and the part you cannot see (strategy). We tend to forget about the part of the iceberg which is hidden under the water.
If I started writing about Sun's mistakes in marketing strategy, it would be an awfully long time before I ran out of things to say. Their marketing communications work is generally good. But in the end, the most tactful thing to say is that Sun is a hardware company trying to do software.
Do you remember the Far Side cartoon with the two deer? One of them has a birthmark on his chest which looks exactly like a bullseye. For someone who writes about marketing strategy, Sun is that deer.
You hurt the ones you love
Please don't pigeonhole me as an anti-Java guy. Yes, I mostly do .NET stuff these days, but I don't get religious about technology. My web server runs Debian. When I repave my Windows box, the first things I install are cygwin and emacs. I sometimes write stuff in Python. I've written lots of Java code, and I really like it. I'm not mad at Java. If anything, I'm mad at Sun for doing such a fine job preventing Java from realizing its full potential.
Back to the topic at hand
The Law of Line Extension says that it is a mistake to take the name of one product and apply it to another. Companies do this often, but it basically never works. We think that the power of the brand will help sell the new product. Instead, the brand itself is tarnished. People start to get confused about what the brand means. Quite often it is necessary to kill the second product before it causes too much damage to the first one.
Confession: SourceGear broke this law when we introduced SourceOffSite Collaborative Edition. We should not have borrowed the name of SourceOffSite for this product. When I critique marketing mistakes, I don't spare myself.
I already wrote about this law back in April when I got all fussy about Golden Oreos. I don't have too much more to say, except...

Jamaica: Woman raped five times
by Jamaica Star(JAMAICA STAR) – Jane Johnson* wore a look of frustration and her eyes welled up with tears as she walked into THE STAR office yesterday.
Johnson said she was on her way to another location, when she looked up and saw the Gleaner building. Needing to unburden herself, she decided to tell her story.
“I have been raped on five different occasions. Even one of my children was conceived during one of the ordeals. I love that little girl with all my heart though, but she is currently with another family who takes really great care of her. They still allow me to keep in contact with her,” she said.
She added that because of the many struggles she has faced, she attempted suicide on several attempts.
Johnson said she was raped at age four by a relative and was forced to go through a similar ordeal at the age of 11, when she was once again molested by somebody known to her. So traumatising were these events that she ran away as a youngster but that did not make her life any easier.
Earlier this year, she got the devastating news that she was HIV-positive
“When I found out I was HIV-positive, I instantly thought about killing myself. I was at the hospital because I was feeling chest pains and the doctors took some blood tests and the results came back positive. I just thought I didn’t deserve to live.
CURRENTLY HOMELESS
Johnson, a 35-year-old mother of five, says she is currently homeless and has spent the last few nights sleeping on a plaza in Portmore.

“I was staying with a friend in another parish several years ago and after she left for work, her boyfriend and his friends put a pillow over my head and took turns raping me. I felt like my body was being destroyed. After that one, my relative’s friend raped me again.  I was on my way home to Portmore and I must have fallen asleep in the taxi because the medications make me sleepy at times. When I woke up, a part of my body was in the bush and my head was out in the road. Somebody later found me and took me to the hospital,” she said.
Now determined to make the rest of her life the best of her life, Johnson says she wants to further her education and land a good job. Though she does not have a birth certificate, Johnson says she hopes she will be able to get one soon.
In the meantime, she is appealing for help from the public.
“I know God is going to work out something for me because I don’t want to go back to my original home. Some of my family members deal with me bad because of my sickness. I want to become a pharmacist and help other persons who are in a similar situation. I have developed other medical conditions because of HIV and it’s really hard. I want to be independent though because is must a reason why God don’t allow me to dead yet,” she said.

This notes describes the alignment between the SWAN - Semantic Web Applications in Neuromedicine - and SIOC - Semantically-Interlinked Online Communities - ontologies, providing a complete model to represent Scientific Discourse in online communities at different levels of granularity (discourse elements and content items). The goal of this alignment is to make the discourse structure and component relationships much more accessible to computation, so that information can be navigated, compared and understood in context far better that at present, across and within domains.
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/.
This W3C Interest Group Note describes how one can use the Semantic Web to express and integrate scientific data. These techniques can be used for modeling any data, and the benefits of integration and model consistency apply to other diverse, distributed data domains. It is hoped that this document will inspire further contributions to the ongoing work at Neurocommons and the Health Care and Life Sciences Interest Group, as well as inspire those in other domains to exploit the Semantic Web.
Background for this document is provided by two companion documents: Semantic Web Applications in Neuromedicine (SWAN) Ontology describes the SWAN ontology for expressing scientific discourse, and SIOC, SIOC Types and Health Care and Life Sciences describes the SIOC ontology for semantically-interlinked online communities. This document describes the the use of SWAN and SIOC together to model discourse within scientific communities.
The document was produced by the Semantic Web in Health Care and Life Sciences Interest Group (HCLS), part of the W3C Semantic Web Activity (see charter). Comments may be sent to the publicly archived<EMAIL_ADDRESS>mailing list.
Publication as an Interest 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.
The disclosure obligations of the Participants of this group are described in the charter.
The SWAN (Semantic Web Applications in Neuromedicine) [SWAN-ONT-JBI] project attempts to model Scientific Discourse about Alzheimer's disease and its supporting evidence in a rich and extensible way that is compatible with the way the domain of Alzheimer's research functions as a technology-mediated knowledge ecosystem. In addition, as described in [SIOC-HCLS], the SIOC (Semantically-Interlinked Online Communities) ontology [SIOC-Specification] can be efficiently used in the Health Care and Life Sciences (HCLS) context as a means to represent the various interactions happening in these communities and their related content in a machine-readable way thanks to Semantic Web technologies.
While not focused on the same objectives, SWAN and SIOC act in a complementary way: SWAN provides fine-grained modeling of scientific discourse elements while SIOC can represent more generic contributions in online communities.
In this note, we present the alignment between the SWAN (version 1.2 [SWAN-HCLS]) and SIOC ontologies, that provides a complete model (based on Semantic Web technologies) to represent Scientific Discourse in online communities at different levels of granularity (discourse elements and content items), a field particularly relevant to the HCLS domain.
In order to define the alignments between the SWAN and SIOC ontologies, a special module for SIOC has been created (the SWAN/SIOC Module). This module contains the different statements defining the alignments (subclasses, subproperties, etc.) between the original ontologies in a machine-readable form, i.e. RDF.
This SWAN/SIOC Module is available at http://rdfs.org/sioc/swan. The following figure identifies the various relationships defined in this module, which are also detailed in the remainder of this note.
Figure 1: The SWAN/SIOC alignments
In order to provide mappings between the classes defining discourse elements (from SWAN, in particular those in the SWAN Citations Ontology and the SWAN Scientific Discourse Module) and more generic Social Web contributions (from SIOC), the following mappings have been defined. The subclass relationships are defined using the rdfs:subClassOf property.
Table 1: Alignment between SWAN and SIOC classes
Since sioc:Post and sioct:Comment are subclasses of sioc:Item, the six classes from SWAN mentioned in the previous table are all subclasses of sioc:Item.
In addition, a class called swansioc:OnlineJournal has been created in the SWAN/SIOC Module for representing journal-type websites where immutable articles are published and comments are allowed on these articles. This class can be used to represent online publications venues such as StemBook. This class has been defined as a subclass of sioc:Container, so that a swanscit:JournalArticle can be linked to its container (swansioc:OnlineJournal) using the sioc:has_container property (inverse sioc:container_of).
In addition to the previous classes, mappings have been defined between different properties of the SWAN Scientific Discourse Relationships Ontology and the SIOC Core Ontology. The following table identifies the defined relationships. The subproperty relationships are defined using the rdfs:subPropertyOf property.
Table 2: Alignment between SWAN and SIOC properties
As one can see when observing these mappings, some of them are redundant. Since they are subproperties of swandisrel:relatedTo, all the previous properties would also become subproperties of sioc:related_to by inference. However, we define such mappings because (1) SIOC applications, that could benefit from these mappings, do not necessarily implement full reasoning and transitive closure over rdfs:subClassOf, and (2) the required computation time when querying data could also benefit from these direct mappings depending on the implementation.
Let us consider once again the ACME Pharma use case that we described in [SIOC-HCLS]. In addition to exposing SIOC information from different services within a company (blogs, wikis, microblogging) in order to integrate them, ACME tools provide a means to let users, when replying to other posts or creating new content (such as wiki pages), to indicate the relationships with other data on the network. Fine-grained modeling of these relationships is provided thanks to SWAN, in particular by using the various properties defined by the SWAN Discourse Relationships Ontology [SWAN-HCLS].
Thanks to the mappings presented in the previous section, as soon as two posts are linked together by such a relationship, a sioc:related_to link is inferred between both, hence enabling distributed conversations on the company network. From a blog post, a user is able to identify that there are several related wiki pages and blog posts. In addition, it is not just these links that can be viewed as sioc:related_to links (in order, for example, to provide a high-level view of a conversation at first glance), but the original SWAN links can also be used to enable more fine-grained navigation, providing ways to zoom in to conversations based on specific relationships.
As an example, when looking at posts about a particular drug treatment, Alice, a researcher at ACME, can immediately identify all related posts (using sioc:related_to links). Then, she may decide to select only the ones disagreeing with the post (via the swandisrel:disagreesWith property) to check if the treatment is appropriate or not. In addition, by using the SIOC Types Module and other properties of SIOC items, she can decide to filter the items so as to browse only the blog posts created by Bob, since she trusts him as an eminent researcher in the domain.
In this note, we described the alignment between the SWAN and SIOC ontologies, published via SIOC's SWAN/SIOC Module. Future direction should include applications of the SWAN/SIOC Module, notably through the Science Collaboration Framework as well as dedicated applications enabling search and navigation from several SWAN knowledge bases.
In addition and following the same idea of unifying discourse representation models to provide better integration of existing data, other mappings between existing RDFS/OWL models for argumentative discussion and scientific discours may be considered, based on models such as aTags [ATAGS], CiTO [CITO], IBIS [IBIS], SALT [SALT] or [SchoolOnto]. For instance, aTags use a subset of the SIOC vocabulary to represent single statements and efforts are under way to represent hundreds of thousands of biomedical statements formalized this way [ATAGS-DATA].
