[SR-Users] Re: Wrong RTP endpoint announced by Kamailio when forwarding calls, but looks correct from RTPEngine

[Leonardo Arena via sr-users]

I've opened the captured traffic with Wireshark and I've found out
that Kamailio is actually forwarding the call with a double SDP
header. ngrep was showing only a partial header. I think this happens
because when forwarding the call I use rtpengine_offer() and not
rtpengine_manage(). I've tried using rtpengine_manage() and I get only
one SDP header but with the (wrong) private IP address. I've tried
also rtpengine_delete() before rtpengine_offer() but there's always a
double header. Ideas? Still digging..

Thanks!

[SR-Users] Wrong RTP endpoint announced by Kamailio when forwarding calls, but looks correct from RTPEngine

[Leonardo Arena via sr-users]

Hi all,

I have the following setup:

Phone <-> private net using TCP transport <-> (172.30.0.156) Kamailio
v5.6.3 + RTPEngine v9.3.1 (22.33.177.156) <-> public net using UDP
transport <-> Asterisk (22.33.178.77)

Phone is registered on Kamailio and forward calls on no answer or when
ext is unregistered, to Asterisk's custom IVR (nodejs app + CouchDB),
using failure_route() [1].

The problem is that when the none answer the phone and the call is
redirected to Asterisk, Kamailio announce its private IP address in
the SDP connection endpoint, hence there is no audio [2]. From
RTPEngine debug logs, it seems that RTPEngine replies with the correct
SDP connection endpoint IP [3]. See also RTPEngine interfaces
definition [4].

What am I missing? Why Kamailio is offering its private IP address in
the SDP connection, instead of its public address when forwarding the
call? If comment "route(SDP_MANAGE_IN)" in route[IN], Kamailio uses
the correct IP endpoint address in the SDP offer when forwarding the
call to Asterisk. But of course this breaks audio when someone answer
the phone. It seems that Kamailio is storing the initial SDP offer
settings and does not update it upon RTPEngine's request, even though
I have added "replace-session-connection" in route[SDP_OFFER_IVR].

Thanks for any help!

Not able to Shutdown or Reboot Debian 12 KDE Plasma

[Losers' Arena]

Respected Sir/ Ma'am

This is to bring to your notice that Debian 12 KDE Plasma is getting stuck
at kvm: exiting hardware virtualization during the Shutdown and Reboot
process. I tried searching for a solution on various Linux Forums but none
of them worked. Here is the list of things I have tried till now:
1) Downloading 'dracut'
2) Updating Grub and Setting DEFAULT TIMEOUTSTOP=30s
3) Setting Debian KDE Plasma to X11
4) Tried Shutting Down using terminal and from System Launcher
5) Finally, I shutdown using the power button of my Laptop. (This works but
is annoying as hell!!)
Some Linux Forums also said that it is a bug and cannot be fixed just like
that. Therefore, I request you to kindly look into this bug and fix it in
the next patch update. Also, please let me know if there is some other
simple fix to this problem.

Regards
Losers' Arena

[grpc-io] Serialize once, send multiple times

[Lorenzo Arena]

I have a question about sending the same message to multiple clients 
(similar to what was asked in the last message 
of https://groups.google.com/g/grpc-io/c/R3XLoLjkFCQ but never got an 
answer). I have a custom gRPC async server, which spawns a "manager" for 
each connection. Each manager is subscribed to a message "publisher"; each 
time someone publish a message it is sent by each manager to the respective 
client, using a shared_ptr. Is there a way to share the already serialized 
buffer instead of sharing the message structure? If I'm understanding 
correctly as of now the message is serialized once for every connection.

Thanks,
Lorenzo

Hi Tomaz,
Let me start by saying I see your passion for it and understand your
point of view. I believe this is my first time ever replying to this
mailing list, by the way. I have read many threads of people
discussing TU Applications. I felt the need to reply because I
recently argued with someone about similar issues to this and did so
starting from a similar point of view as you I believe, where I was
against the seemingly corporate-like checklists/procedures. The person
knew me and I felt insulted that they were making me go through with
something that seemingly implied that I was lying. I have actually
changed my point of view on this though after discussing it with
coworkers several times. The real importance of following
checklists/procedures like this, as I was convinced to realize, is
that they force fairness and transparency. It prevents nepotism, or
even possibly people being deceived and getting someone they thought
was a friend online past the normal procedures, and having them turn
out to be malicious. It is not accusing you or anyone of it, but it is
to make things fair. I think that is important in a community like
this. Treat people fairly. This way we don't have to try to guess who
has malicious intent and treat them differently than someone else 1
person thought they knew.

All community members, on a side note, although I haven't read much
into it, I think it is great to see the role is now "package
maintainer". I have said to myself after reading many of these
applications and seeing the current TUs interview the person applying
mostly about their technical ability, that all of these technical
questions are not really confirming the part I worry more about with
the AUR, and what is in the name of a "TU", _TRUST_. A person with
malicious intent, could, and most likely would be, technically
capable. They could easily pass that part of it with minimal effort.
Very few of these applications seem to have a way to actually confirm
that the person applying is TRUSTED. Now, I know everywhere it says
the AUR is not to be trusted, and we must confirm all PKGBUILDs during
build, but let's be real, with git packages and sources being pulled
from many unheard of remote websites, that can be tough. I do review
almost every PKGBUILD I use from the AUR, but I often wonder about the
git url it is pulling from, and only sometimes do I go there and take
a quick look at it. This can be a tough balance between confirming
trust, and keeping people's privacy though. I am not sure though if
more investigation is done behind closed doors to confirm those things
but keep people's private information, well, private.

Sorry to go off on a bit of a rant there on the side note. I hope my
formatting was satisfactory for everyone (plain text and
bottom-replying, right? haha.). I see there have also been a couple
emails pop up since I typed this up. Sorry if this has now become
repetitive, out of place, or further derailed the conversation on the
actual application process.

Kind regards,
Dan

In the generated classes on the root element the extension  is 
applied (the 'Type' suffix has been removed and a list member has the plural 
name 'invoiceBodies') but for nested complex types this seems to not have any 
effect (all the classes have names like 'InvoiceHeaderType', 'InvoiceBodyType' 
and so on and list members have the singular name).
 Am i doing something wrong and maybe there is some configuration i am missing 
to recursively apply xjc:simple to all nested complex types?

Dario Arena commented on GROOVY-10026:
--

[~emilles] yes you are right, maybe i badly explained myself. My concern was 
more on making chained collections and iterators call more efficient. Recently 
i was tinkering with some code that requires streaming lines of text from big 
.csv files that does not fit in memory and i noticed that if i call 
".collect()" on a stream the function that is called is 
??public static  java.util.List collect(@Nullable Object self, 
groovy.lang.Closure transform)??
where in the closure i define some transformation for every element in the 
stream (like if in java i use java .map(..).collect(Collectors.toList()) ) and 
it works! 
I was wondering if maybe there was a way to generalize this behaviour for all 
collections and avoid to call .stream() at the beginning and because the GDK 
itself handle lazy evaluation and "materialization" of the results in a more 
transparent way for the user

[~daniel_sun] GINQ is very nice, i didn't know that this was coming in Groovy 
4. There is even an entry in the changelog under "New Features" but i missed 
it. :P (maybe when Groovy 4 will come out it would need more "highlighting"). 
[~emilles] These are all very good ways to implement the "every statement is 
indeed an expression". I was thinking however of a more direct support from the 
language itself without doing the extra step of implementing these constructs. 
Maybe this could be an idea to consider for a future version of Groovy (5.0)

[jira] [Updated] (GROOVY-10026) Update the GDK to better support java streams and Publish/Subscribe API

[Dario Arena (Jira)]

 [

Dario Arena updated GROOVY-10026:
-
Description: 
Groovy is one of the first JVM languages to introduce "internal iteration" and 
in general collections operations like collect(), find(), collate().
Maybe now that java has streams and a publish/subscribe API some of this 
operations could be reworked and implemented using some of this features.
The first thing to improve could be a lazy evaluation of chained collections 
method calls, but without introducing in groovy the need to insert a "terminal 
operation" at the end of the chain.
Just as an example if i write something like

{quote}def employeeSorted = employee.findAll \{ it.qualification == 'intern' 
}.sort\{ daysBetween(it.hired, now) }

if (monitorTop5Interns) \{
print employeeSorted.take(5)
}{quote}

When monitorTop5Interns is false there is no need to scan all the employee list 
to find all the interns because, at least at this point in time, 
"employeeSorted" is not evaluated. Even if it is true, because of the "take(5)" 
as the last operation once top 5 elements are found there is no need to scan 
the rest of the list.
Is it possible to implement some "intermediate decorator objects" that maybe 
extends they're correspective type (List, Set, Iterable, Collection...) that 
are automatically coerced to an actual concrete type (a java.util.ArrayList, a 
java.util.String...) only when they are actually evaluated (e.g. a 
"subscription" in the publish/subscribe semantics)?.
I know that for every collection one could call .stream() or wrap the 
collection in a "Producer" like in RxJava but wouldn't it be groovy-er if this 
is transparent for the users?

[jira] [Updated] (GROOVY-10025) "Assimilate" expressions from other languages (Scala, Python...)

[Dario Arena (Jira)]

 [ 
https://issues.apache.org/jira/browse/GROOVY-10025?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
 ]

Dario Arena updated GROOVY-10025:
-
Description: 
In some other languages (Scala, Python, Haskell, Java 14 switches) every 
statement like if..else, for, switch... is indeed an expression that returns a 
value (usually the last one computed is implicitly returned as in Groovy).

Would it be possible to include something like conditional expression, for 
comprehensions and switch expressions as a native groovy feature? I think it 
would simplify writing DSLs and maybe in some cases making groovy code neater 
and readable

Using closures it is possible to write "conditional expressions" without using 
the conditional operator, something like:

{quote}{{def pillToTake = \{ if(candidate.name == "Neo") "red" else "blue" 
}.call()}}{quote}

but maybe if groovy supports expression this could be written as

{quote}{{def pillToTake = if candidate.name == "Neo" then "red" else 
"blue"}}{quote}

or maybe using switch expression to include more complex cases

{quote}def trainingSchedule = switch(date) \{
case \{ isHoliday(it) }: return ['Rest']   
case  \{ date.dayOfWeek in [MONDAY, FRIDAY] }: return ['Run 15m', '40 
Push-Ups', '20 Crunches']   
case  \{date.dayOfWeek.is(WEDNESDAY) }: return ['Run 10m', '50 Tractions', 
'30 Squats']   
default: return ['Run 30m']
}{quote}


I've not really dug deep in how the groovy compiler works but maybe recognizing 
these expression, "wrapping" them in a closure and calling that closure could 
be done automatically?

For comprehensions maybe are a little bit more tricky to implement as a native 
groovy feature and using .collect(..) the code is equally readable, but maybe 
in some cases one could prefer to use a different construct

Actual groovy code:

{quote}def prices = stocks.filter \{ it.market == "NASDAQ"}.collect\{ 
getPriceFor(it) \}{quote}

Using for comprehension:

{quote}def prices = [getPriceFor(stock) for stock in stocks if stock.market == 
"NASDAQ"]{quote}

It is just a matter of preference which one is more readable but this could 
simplify the "flow" of the code in some cases.

[jira] [Updated] (GROOVY-10025) "Assimilate" expressions from other languages (Scala, Python...)

Dario Arena updated GROOVY-10025:
-
Description: 
In some other languages (Scala, Python, Haskell, Java 14 switches) every 
statement like if..else, for, switch... is indeed an expression that returns a 
value (usually the last one computed is implicitly returned as in Groovy).

Would it be possible to include something like conditional expression, for 
comprehensions and switch expressions as a native groovy feature? I think it 
would simplify writing DSLs and maybe in some cases making groovy code neater 
and readable

Using closures it is possible to write "conditional expressions" without using 
the conditional operator, something like:

{quote}{{def pillToTake = \{ if(candidate.name == "Neo") "red" else "blue" 
}.call()}}{quote}

but maybe if groovy supports expression this could be written as

{quote}{{def pillToTake = if candidate.name == "Neo" then "red" else 
"blue"}}{quote}

or maybe using switch expression to include more complex cases

{quote}def trainingSchedule = switch(date) \{
case \{ isHoliday(it) }: return ['Rest']   
case  \{ date.dayOfWeek in [MONDAY, FRIDAY] }: return ['Run 15m', '40 
Push-Ups', '20 Crunches']   
case  \{date.dayOfWeek.is(WEDNESDAY) }: return ['Run 10m', '50 Tractions', 
'30 Squats']   
default: return ['Run 30m']
}{quote}


I've not really dug deep in how the groovy compiler works but maybe recognizing 
these expression, "wrapping" them in a closure and calling that closure could 
be done automatically?

For comprehensions maybe are a little bit more tricky to implement as a native 
groovy feature and using .collect(..) the code is equally readable, but maybe 
in some cases one could prefer to use a different construct

Actual groovy code:

{quote}def prices = stocks.filter \{ it.market == "NASDAQ"}.collect\{ 
getPriceFor(it) \}{quote}

 
Using for comprehension:

 
def prices = [getPriceFor(stock) for stock in stocks if stock.market == 
"NASDAQ"]


It is just a matter of preference which one is more readable but this could 
simplify the "flow" of the code in some cases.

-
Description: 
In some other languages (Scala, Python, Haskell, Java 14 switches) every 
statement like if..else, for, switch... is indeed an expression that returns a 
value (usually the last one computed is implicitly returned as in Groovy).

Would it be possible to include something like conditional expression, for 
comprehensions and switch expressions as a native groovy feature? I think it 
would simplify writing DSLs and maybe in some cases making groovy code neater 
and readable

Using closures it is possible to write "conditional expressions" without using 
the conditional operator, something like:

{{def pillToTake = \{ if(candidate.name == "Neo") "red" else "blue" }.call()}}

but maybe if groovy supports expression this could be written as

{{def pillToTake = if candidate.name == "Neo" then "red" else "blue"}}

or maybe using switch expression to include more complex cases

 

def trainingSchedule = switch(date) {   

    case \{isHoliday(it)}: return ['Rest']   

    case \{date.dayOfWeek in [MONDAY, FRIDAY]}: return ['Run 15m', '40 
Push-Ups', '20 Crunches']   

    case \{date.dayOfWeek.is(WEDNESDAY)}: return ['Run 10m', '50 Tractions', 
'30 Squats']   

    default: return ['Run 30m']

{{}}}

 

{{I've not really dug deep in how the groovy compiler works but maybe 
recognizing these expression, "wrapping" them in a closure and calling that 
closure could be done automatically?}}

{{For comprehensions maybe are a little bit more tricky to implement as a 
native groovy feature and using .collect(..) the code is equally readable, but 
maybe in some cases one could prefer to use a different construct}}

In some other languages (Scala, Python, Haskell, Java 14 switches) every

[QE-users] QE + Wannier90 + problem with spn file

[Arena Konta]

Dear QE Users

I have a problem with spn files. I prepared calculations with various version 
of QE (6.6, 6.5, 6.2.1) with p2wannier90 and wannier90 (version 3.1). 
Everything seems to be ok, expect, when I run postwannier90 app I got error:

* Energy bands in eV, coloured by SHC

   * Berry curvature-like term for spin Hall conductivity in Ang^2

What can be wrong with this file? I did diffrent calculations using ELK and the 
same wannier90 library, and everything seems to be also OK.

Re: Feature request, but must be universallly accepted by ALL blanker authors

[Dan Arena]

Gene,

Following up more about xfce4, you should be able to go into their
Settings Manager and you can turn off the Screensaver and uncheck
Power Management under the Advanced tab. You will still want to add
the lines I mentioned before into /etc/X11/xorg.conf to prevent the
screen from going blank though.

I also think it would be a useful feature for LinuxCNC to include an
option where it itself can prevent screensavers. This would not be too
hard for them to do, see https://stackoverflow.com/a/31504731/1941627

A friend also just brought up a good point... do these machines not
have a physical emergency stop button? It seems like with them being
as dangerous as you say they are, they should. I know the couple mills
I have seen do.

I would also take this issue up with the LinuxCNC community. Is it
supposed to work like that? Does a new install from the LinuxCNC
"Install DVD" behave the same?

Thanks,
Dan

Re: Feature request, but must be universallly accepted by ALL blanker authors

[Dan Arena]

Good afternoon Gene,

I am not sure about xfce, I suspect they do have settings in their GUI
settings manager to adjust what you want, but seeing as this is the
xorg mailing list I will tell you how I do it when running just X with
a simple window manager. This is probably what you want. I put these
lines into my /etc/X11/xorg.conf file on an appliance-like system for
non-linux users. The first two settings DontVTSwitch and DontZap
aren't actually related to "screen blanking", they prevent you from
using ctrl+alt+f1 and ctrl+alt+backspace. You can delete them if you
want.

Section "ServerFlags"
Option "DontVTSwitch" "on"
Option "DontZap"  "on"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection


Anyways, thanks for the entertaining email.

Happy Friday!

-Dan

[Origami] The Unbelievable Practice of Paper Art

Prevent X with ZaphodHeads from creating a :0.1 screen when monitor is disconnected

[Dan Arena]

Good morning,

This is kind of an odd setup I am doing. I am usually using 2
monitors, and want separate X screens for each, so :0.0 and :0.1, but
if the 2nd monitor is not connected I do not want :0.1 to be created.
Up until now I have been using the nvidia driver, which by default has
an option "AllowEmptyInitialConfiguration" set to false, which
prevents the :0.1 from being created when the 2nd monitor is not
connected at startup. I would like to have this same behavior with the
intel or modesetting driver and ZaphodHeads. I am currently using the
intel driver on CentOS 7 since modesetting was tearing, but if need be
I can probably switch to modesetting and turn on some other options to
stop the tearing.

With the intel driver, if the 2nd monitor is disconnected, :0.1 is
still created and is just a 1024x768 framebuffer. The main problem
this is creating is the java application I am using still thinks there
are 2 "monitors" available. It uses
GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices()
to determine the "number of monitors connected". The developer keeps
insisting that I fix my OS setup to report the proper number of
monitors connected. The 2nd monitor is used only for displaying a
video, which is why I want it on another X screen; this way the mouse
cannot move over there, and screenshots can be easily taken of each
monitor separate.

Any ideas?

Note, I am not using a DE, but just running startx with xinitrc that
starts a window manager (metacity).

Below is my current xorg.conf. I tried experimenting with a couple
other configurations, like removing all but the Device sections, and
turning on Option "ReprobeOutputs", with no luck. It either never
creates :0.1, or always does.

Thanks,
Dan

[Origami] Kuala Lumpur folders

[Xander Arena]

Hello,

My brother has recently moved to Kuala Lumpur and I wondered if anybody
knows of folders or folding groups in that city? His youngest son has taken
a keen, and talented, turn toward origami.

Thanks in advance,

[chrony-users] source that exceeds maxdistance causing some odd issues

[Dan Arena]

Hello,

I am using chrony 3.2 on RHEL 7.6. I was trying to find out why my
clock seemed to be out of sync with the NTP server despite chrony
running and the 1 NTP server I had configured was online. I turned on
"log measurements" which in the chrony.conf man page says:

   measurements
   This option is identical to the rawmeasurements option,
except it logs only valid measurements from synchronised sources, i.e.
measurements which passed the RFC 5905 tests 1 through 7. This can be
useful for producing graphs of the source’s performance.

This specifically says "only valid measurements from synchronised
sources", but It was still showing log lines for the source. When I
looked at `chrony sources -v` it listed the source state as "?", which
is quite confusing because the source is not actually "unreachable". I
tracked the issue down to the source reporting a root dispersion of
5.4 seconds. If I increase the "maxdistance" then chrony shows the
source as online.

Why does chrony show the source as " '?' = unreachable", instead of
like "'x' = time may be in error"? Why are there lines in the
measurements file when the source is not synchronised? My
servers(doesn't include the NTP server) will be together on a LAN,
without a gateway to the internet. The NTP server is provided by
someone else, and I am not sure if it will be synced with an external
source. Can someone provide some insight/recommendations here please?
Should I just leave the maxdistance at 16.0? I am kind of inclined to
blame the person managing the NTP server; they should probably sync
its time regularly some how, either manually or from an external
source (over internet or GPS, whatever).

Thanks,
Dan

[QE-users] Three-dimensional plot of a band structure

[Arena Konta]

Hi all,

Any advice how to create 3D plot of a band structure in QE? It means, for 
example, axis x == kx,  y = ky and z = E ?

Thank you in advance

Re: [Origami] Ease of open back models

[Xander Arena]

On Mon, Apr 22, 2019 at 9:00 AM


*"I remember reading somewhere that more origami models are open back
because*


*some design issue but I went back to my ODS book (which is where I think
Isaw that information) and couldn't find the explanation. So would anyone*
*please enlight me?"*


I'll venture to say that it's easier to bring folds together along a
central axis, which creates an open back when folded in half. The paper can
be folded to have a closed back, but this requires a bit more paper/spacing
delegated to the spine. Since the closed back models use precious paper
resource to make the continuous surface, adding additional flaps is
slightly more challenging because less paper is available.

At least in animal origami, where creatures typically have an axial
skeleton and appendicular features...

[Tinyos-help] [SmartSyS 2019] [FINAL CALL- DEADLINE APPROACHING]: Call for papers

[Antonio Arena]

[We apologize if you receive multiple copies of this CFP.]

DEADLINE APPROACHING  - CALL FOR PAPERS - IEEE SmartSys 2019
Fourth IEEE Workshop on Smart Service Systems (SmartSys)
Co-located with the IEEE International Conference on Smart Computing (SMARTCOMP 
2019)
Washington D.C., June 12th/15th, 2019
http://mpsc.umbc.edu/smartsys/2019/

Technology succeeds when it provides benefits to the society either directly or 
indirectly. Understanding the societal and economic impact and human-centered 
aspects of a smart system or technology in advance and designing the system 
a-priori with potential value-added services help spur the discoveries of new 
tools, methodologies and innovative services.  Smart service systems span 
across a variety of socio-technical facets comprising of devices, people, 
organizations, environments, and technologies to sense, actuate, control and 
assess the physical, cyber and societal artifacts of the human service systems. 
Besides the systems being self-adaptive and fault-tolerant, need to be designed 
in such a way that it can continuously increase the quality and productivity, 
the compliance and sustainability of the smart services it offers. While 
human-centered perspective and cognitive learning help create multi-facet value 
added services and catalyze the sustained economic growth of smart service 
systems, understanding the multi-modal sensing, control, heterogeneity and 
interdependency between different physical, virtual and logical components of 
such a complex system will enable the realization of new transformative smarter 
service systems. If successful, this can help improve the quality-of-service of 
the customers, quality-of-life of the citizens and quality-of returns of the 
stakeholders and investors.
Nurturing the development of smart service systems seeks for inter- and 
trans-disciplinary crosscutting research threads from system and operational 
engineering, computer science and information systems, social and behavioral 
science, computational modeling and industrial engineering etc.  The goal of 
this workshop is to bring together practitioners and researchers from both 
academia and industry in order to have a forum for discussion and technical 
presentations on the fundamental knowledge and principles of  smart service 
systems that enable the value co-creation in sensing, actuating, data 
analytics, learning, cognition, and control of human centric 
cyber-physical-social systems and future of work.. 
Research contributions are solicited in all areas pertinent to smart human 
services and systems, including:
• Innovative technologies, tools, methodologies and solutions for smart service 
systems; example includes personalized healthcare, smart energy, smart cities, 
smart manufacturing, intelligent transportation, education, precision medicine 
and agriculture, national security etc. 
• Information extraction and interpretation from sensors, actuators, smart 
phones, smart watch, and human
• Context and situational-awareness of smart service systems
• Design of people-centric services and technologies for providing better 
services such as food, transportation and places to live
• Novel architectures and interoperable solutions for internet of things
• Models and methodologies for designing complex smart systems 
• Big data analytics approaches for innovative smart services
• Modeling, analysis, co-production, and co-evolution of human activity, 
behavior and interaction for the effective adaptation and percolation of 
longitudinal smart service systems
• Role of machine learning, artificial intelligence, robotics, pervasive 
computing, control theory, information and communications technologies
• Design and developments of intelligent systems, intelligent enterprises and 
cyber-physical-social-systems
• Design of inter-dependent complex global systems such as healthcare, smart 
gird, computer networks, logistics and supply-chains, financial markets etc.
• Smart infrastructure and testbed to support the integration and test of 
autonomous systems and innovative applications

Re: [QE-users] Problem with generating q-points for lambda

[Arena Konta]

Dear Professors Paolo and and Hari,
 
I appreciate your both help. However, I am still a little bit confused which 
weights should I chose for lambda.x file. For example:
 
bravais-lattice index =    7
 lattice parameter (alat)  =   7.9506  a.u.
 unit-cell volume  = 591.7416 (a.u.)^3
   
 celldm(1)=   7.950626  celldm(2)=   0.00  celldm(3)=   2.354822
 celldm(4)=   0.00  celldm(5)=   0.00  celldm(6)=   0.00
 
scf calculations on the mesh 4x4x4 give me:
 
number of k points=    13  Marzari-Vanderbilt smearing, width (Ry)=  0.0200
   cart. coord. in units 2pi/alat
    k(    1) = (   0.000   0.000   0.000), wk =   0.0312500 = 2
    k(    2) = (  -0.250   0.000   0.1061651), wk =   0.250 = 16
    k(    3) = (   0.500   0.000  -0.2123303), wk =   0.125 = 8
    k(    4) = (  -0.250   0.250   0.2123303), wk =   0.250 = 16
    k(    5) = (   0.500   0.250  -0.1061651), wk =   0.500 = 32
    k(    6) = (   0.250   0.250   0.000), wk =   0.125 = 8
    k(    7) = (   0.500  -0.500  -0.4246605), wk =   0.0625000 = 4
    k(    8) = (   0.000   0.000   0.2123303), wk =   0.0625000 = 4
    k(    9) = (   0.750   0.000  -0.1061651), wk =   0.250 = 16
    k(   10) = (   0.500   0.000   0.000), wk =   0.125 = 8
    k(   11) = (   0.750  -0.750  -0.4246605), wk =   0.125 = 8
    k(   12) = (   0.500  -0.500  -0.2123303), wk =   0.0625000 = 4
    k(   13) = (   0.000   0.000  -0.4246605), wk =   0.0312500 = 2
(there is no inversion in crystal structure)
 
ph.x calculations are following:         
         
        Dynamical matrices for ( 4, 4, 4)  uniform grid of q-points
 (  13q-points):
   N xq(1) xq(2) xq(3)
   1   0.0   0.0   0.0
   2  -0.25000   0.0   0.106165127
   3   0.5  -0.0  -0.212330253
   4  -0.25000   0.25000   0.212330253
   5   0.5   0.25000  -0.106165127
   6   0.25000   0.25000   0.0
   7   0.5  -0.5  -0.424660507
   8   0.0   0.0   0.212330253
   9   0.75000  -0.0  -0.106165127
  10   0.5  -0.0   0.0
  11   0.75000  -0.75000  -0.424660507
  12   0.5  -0.5  -0.212330253
  13   0.0  -0.0  -0.424660507
 
Therefore, we can say that both q- and k-meshes are "exactly" the same in scf 
and ph calculations. However, when I generate k-mesh using kpoints.x, the set 
is equivalent, but the weights and order are different:
 
      
      
       ***
 * *
 *   Welcome to the special points world!  *
 * *
 *    1 = cubic p (sc )  8 = orthor p (so )    *
 *    2 = cubic f (fcc)  9 = orthor base-cent. *
 *    3 = cubic i (bcc) 10 = orthor face-cent. *
 *    4 = hex & trig p  11 = orthor body-cent. *
 *    5 = trigonal   r  12 = monoclinic  p *
 *    6 = tetrag p (st )    13 = monocl base-cent. *
 *    7 = tetrag i (bct)    14 = triclinic   p *
 ***

[Tinyos-help] [SmartSyS 2019]: Call for papers

[Antonio Arena]

[We apologize if you receive multiple copies of this CFP.]

CALL FOR PAPERS - IEEE SmartSys 2019
Fourth IEEE Workshop on Smart Service Systems (SmartSys)
Co-located with the IEEE International Conference on Smart Computing (SMARTCOMP 
2019)
Washington D.C., June 12th/15th, 2019
http://mpsc.umbc.edu/smartsys/2019/

Technology succeeds when it provides benefits to the society either directly or 
indirectly. Understanding the societal and economic impact and human-centered 
aspects of a smart system or technology in advance and designing the system 
a-priori with potential value-added services help spur the discoveries of new 
tools, methodologies and innovative services.  Smart service systems span 
across a variety of socio-technical facets comprising of devices, people, 
organizations, environments, and technologies to sense, actuate, control and 
assess the physical, cyber and societal artifacts of the human service systems. 
Besides the systems being self-adaptive and fault-tolerant, need to be designed 
in such a way that it can continuously increase the quality and productivity, 
the compliance and sustainability of the smart services it offers. While 
human-centered perspective and cognitive learning help create multi-facet value 
added services and catalyze the sustained economic growth of smart service 
systems, understanding the multi-modal sensing, control, heterogeneity and 
interdependency between different physical, virtual and logical components of 
such a complex system will enable the realization of new transformative smarter 
service systems. If successful, this can help improve the quality-of-service of 
the customers, quality-of-life of the citizens and quality-of returns of the 
stakeholders and investors.

[QE-users] Problem with generating q-points for lambda

[Arena Konta]

Hello,

I try to do el-ph calculations for noncentrosymmetric compounds (  tetragonal 
BaNiSn3-type crystal structure, with space group I4mm (no. 107)) using QE 
6.2.1: 
 
The calculations ph.x for q = 4 4 4 look follow:
 
bravais-lattice index =    7
celldm(1)=    7.90529  celldm(2)=    0.0  celldm(3)=    2.36005
 
 Dynamical matrices for ( 4, 4, 4)  uniform grid of q-points
 (  13 q-points):
   N xq(1) xq(2) xq(3)
   1   0.0   0.0   0.0
   2  -0.25000   0.0   0.105929929
   3   0.5   0.0  -0.211859857
   4  -0.25000   0.25000   0.211859857
   5   0.5   0.25000  -0.105929929
   6   0.25000   0.25000   0.0
   7   0.5  -0.5  -0.423719715
   8   0.0   0.0   0.211859857
   9   0.75000   0.0  -0.105929929
  10   0.5   0.0   0.0
  11   0.75000  -0.75000  -0.423719715
  12   0.5  -0.5  -0.211859857
  13   0.0   0.0  -0.423719715
 
 
The DOS and q-freq are OK. Then I need to generate q-points for lambda.in.  
Using kpoints.x program I get:
      
     bravais lattice  >> 7
 filout [mesh_k]  >> Mesh
 enter celldm(3)  >> 2.36005
 mesh: n1 n2 n3   >> 4 4 4
 mesh: k1 k2 k3 (0 no shift, 1 shifted) >> 0 0 0
 write all k? [f] >>
 
 # of k-points   ==    13  of    64
    13
    1   0.000  0.000  0.000   1.00
    2   0.250 -0.250  0.000   4.00
    3   0.500 -0.500  0.000   2.00
    4   0.000  0.250  0.1059300   8.00
    5   0.500 -0.250  0.1059300  16.00
    6   0.000  0.500  0.2118599   4.00
    7   0.250  0.250  0.2118599   8.00
    8   0.000  0.000  0.2118599   2.00
    9   0.500 -0.500  0.2118599   2.00
   10   0.000  0.250  0.3177899   8.00
   11   0.000  0.500  0.4237198   4.00
   12   0.250  0.250  0.4237198   4.00
   13   0.000  0.000  0.4237198   1.00
 
Question: 
(1) why the q-points are not the same (at least in the same order?
(2) how to guess weight of q-points from the output ph.x ?
      
 Thank you for any help

Re: [Origami] ORIGAMI TRAFFIC NOISE BARRIER

[Xander Arena]

Hello team o-list,

The concept of a modulating array for traffic noise barriers was
interesting to me.

You know how sound reduction panels often have different angles or cones to
break up the waves? Do we know of a tessellation pattern that might be
useful, so that a steel sheet might be folded in an effective manner as a
vertical barrier?

My parents are looking for a solution to the noise at their home and are
considering different options, with a steel wall being one of them,

[QE-users] gfortran vs intel lead to different results of electron-phonon coupling by ph.x

Hi everyone,
 
Using the same input files (from one of the tutorials, step-by-step), I got 
different output files of dynamical matrices when using different intel 
compilators (Intel 13, Intel 15 and Intel 16). Only the results using GNU 
gfortran are correct. In all calculations, there is no significant error of 
freqs. In turn, all scf calculations (intel and gnu) also work fine.

Re: [AsteriskBrasil] Demora para Completar ligação

[Giliardy Arena]

Boa tarde.
Obrigado pela resposta, Rogerio.

Sim , já testei como uma extensão simples e o cenário é o mesmo.

No CLI eu só enxergo LOG quando a chamada é conectada.
Não consigo ver nada diferente antes desse momento.

Via tcpdump eu vejo as tentativas, mas não consigo identificar a causa do
atraso através dele.
Me chamou atenção a tentativa do Asterisk em todos os IPs do Call Manager,
quando ele deveria se conectar diretamente ao que enviou a chamada.

Você tem alguma sugestão que eu possa fazer no CLI para tentar enxergar a
tentativa desde o recebimento do INVITE ?

Atenciosamente,
Giliardy Correia Arena.

Olá , bom dia.

Alguém sugere alguma forma de eu rastrear a ligação desde a chegada da
requisicao SIP no servidor Asterisk , para entender o motivo de demorar
muito para conectar? Algum debug específico, um trace , um log...

Obrigado

O waitforsilence é para identificar se não tiver mais conversação e

Para evitar ficar alguma chamada presa gravando eternamente.

[AsteriskBrasil] Demora para Completar ligação

[Giliardy Arena]

Caros,
Boa tarde.

Estou aprendendo e estudando sobre o Asterisk.
Atualmente administro um Cisco Call Manager e a minha ideia é usar o
Asterisk para gravar ligações recebidas do Call Manager.

Fiz a integração do Asterisk com o Call Manager com sucesso.

Estou com problema para entender o motivo do Asterisk demorar para conectar
a ligação a uma extensão. Tenho pesquisado, mas com dificuldades para
entender como debugar.

Criei a seguinte extensão, que atende sozinha e grava.

exten => 2005,1,Answer()
exten =>
2005,n,MixMonitor(Ramal-${CALLERID(num)}-Em-${STRFTIME(${EPOCH},,%d-%m-%Y-%H-%M)}.wav)
exten => 2005,n,WaitForSilence(1|6)
exten => 2005,n,Hangup


Também experimentei o mesmo sintoma através de uma extensão que criei e
loguei numa softphone.

- Ativei Debug full , mas não tem nenhuma mensagem importante. Apenas o que
vejo na CLI do asterisk

- Na CLI do Asterisk só vejo log quando a chamada efetivamente é conectada,
não sei se consigo ver desde o momento que ele recebe a requisição.

- Fiz um TCPDUMP e realmente me parece que é o Asterisk demorando a
conectar a extensão, mas via TCPDUMP não tenho detalhes para entender e
ajustar. Demora aproximadamente 30segundos após chamar do Call Manager.


Alguém pode me dar um help de por onde eu posso rastrear para tentar
corrigir ?

Obrigado!

Atenciosamente,
Giliardy Correia Arena.

Yes, I believe you are correct the screen seems to be failing.  There are parts 
of the screen that have different contrasts. When i adjust the contrast those 
area get brighter and darker but not at the same rate.  Do you know where I can 
get a spare screen?  Besides purchasing another unit from eBay?

Hi!

Yeah, everything seems stable on the +-5v side. I will try to replace all the 
caps.  But probably the screen is going bad :(

Re: [M100] Tandy Model 100

[Rafael Arena]

Hi!

I tried what was suggested and I get 0-3.8v on pin four (without the screen 
plugged in).  Can’t seem to figure out how to measure pin 4 with the screen 
plugged in.  When i turn the contrast knob the screen starts to jump around the 
display random line sporadically.  I have to turn the computer on and off a few 
times in order to get it to come on.

Thank you,

Hi,

At times the computer comes on and when adjusting the screen display the image 
gets all distorted and then fades away.  I have checked the +5 and -5 volts 
that the screen needs and I get +5 and -4.8 volts respectively. I changed 
capaciitor ‘C85’ and checked all the memory chips.  Like I said it works every 
now and again, missing a few lines on the screen.  When i play with the 
contrast knob the image distorts and some times fades away.  Any of this makes 
sense? Lol

Thank you,

You may be able to clean it with Deoxit D5.

Drench it good. Work the knob a few times a day for a few days. Give it at 
least a week to dry out and act normal.

While the stuff is still wet, the screen may go totally blank, meaning no 
darkened pixels, or just microscopically faintly under just the right extreme 
angle of light.

But by a week maybe a little more it does dry out and the pot will either be 
better than before, or the same as before, depending on if the original problem 
was dirt & oxidization or not. But it doesn't hurt anything. (plastics, traces, 
etc)

CALL FOR PAPERS - IEEE SmartSys 2018 – EXTENDED DEADLINE: 15 March 2018

Third IEEE Workshop on Smart Service Systems (SmartSys)

Co-located with the IEEE International Conference on Smart Computing (SMARTCOMP

Technology succeeds when it provides benefits to the society either directly or 
indirectly. Understanding the societal and economic impact and human-centered 
aspects of a smart system or technology in advance and designing the system 
a-priori with potential value-added services help spur the discoveries of new 
tools, methodologies and innovative services.  Smart service systems span 
across a variety of socio-technical facets comprising of devices, people, 
organizations, environments, and technologies to sense, actuate, control and 
assess the physical, cyber and societal artifacts of the human service systems. 
Besides the systems being self-adaptive and fault-tolerant, need to be designed 
in such a way that it can continuously increase the quality and productivity, 
the compliance and sustainability of the smart services it offers. While 
human-centered perspective and cognitive learning help create multi-facet value 
added services and catalyze the sustained economic growth of smart service 
systems, understanding the multi-modal sensing, control, heterogeneity and 
interdependency between different physical, virtual and logical components of 
such a complex system will enable the realization of new transformative smarter 
service systems. If successful, this can help improve the quality-of-service of 
the customers, quality-of-life of the citizens and quality-of returns of the 
stakeholders and investors.

Nurturing the development of smart service systems seeks for inter- and 
trans-disciplinary crosscutting research threads from system and operational 
engineering, computer science and information systems, social and behavioral 
science, computational modeling and industrial engineering etc.  The goal of 
this workshop is to bring together practitioners and researchers from both 
academia and industry in order to have a forum for discussion and technical 
presentations on the fundamental knowledge and principles of  smart service 
systems that enable the value co-creation in sensing, actuating, data 
analytics, learning, cognition, and control of human centric 
cyber-physical-social systems.

Research contributions are solicited in all areas pertinent to smart human 
services and systems, including:

• Innovative tools, methodologies and solutions for smart service systems; 
example includes personalized healthcare, smart energy, smart cities, smart 
manufacturing, intelligent transportation, education, precision medicine and 
agriculture, national security etc.

• Information extraction and interpretation from sensors, actuators, smart 
phones, smart watch, and human

• Context and situational-awareness of smart service systems

• Design of people-centric services and technologies for providing better 
services such as food, transportation and places to live

• Novel architectures and interoperable solutions for internet of things

• Models and methodologies for designing systems of systems

• Big data analytics approaches for providing better customer services, and 
innovating new types of sustainable services

• Modeling, analysis, co-production, and co-evolution of human activity, 
behavior and interaction for the effective adaptation and percolation of 
longitudinal smart service systems

• Role of machine learning, artificial intelligence, robotics, pervasive 
computing, control theory, information and communications technologies

• Design and developments of intelligent systems, intelligent enterprises and 
cyber-physical-social-systems

• Design of inter-dependent complex global systems such as healthcare, smart 
gird, computer networks, logistics and supply-chains, financial markets etc.

• Smart infrastructure and testbed to support the integration of autonomous 
systems and innovative applications

Dear prof. Paolo Giannozzi

Thank you for quick response. Please, clarify me: I set variable
"use_all_frac=.true." and option "verbosity='high'" and get output showed
below. Hoverwer, I am still unable to find the right values of frac. trans

*

Set variable "use_all_frac=.true." and option "verbosity='high'". This will
find and print all symmetries and associated fractional translations. If a
fractional translation along a crystal axis is 1/n, with n integer, the FFT
dimension along that axis must contain a factor n. If you do not need
hybrid functionals or phonons, just set variable "use_all_frac=.true."

[Tinyos-help] CFP: Third IEEE Workshop on Smart Service Systems (SmartSys)

[Antonio Arena]

[We apologize if you receive multiple copies of this CFP.]

 

CALL FOR PAPERS - IEEE SmartSys 2018

Third IEEE Workshop on Smart Service Systems (SmartSys)

Co-located with the IEEE International Conference on Smart Computing (SMARTCOMP 
2018)

Sicily, June 18th/20th, 2018

http://mpsc.umbc.edu/smartsys/2018/

 

Technology succeeds when it provides benefits to the society either directly or 
indirectly. Understanding the societal and economic impact and human-centered 
aspects of a smart system or technology in advance and designing the system 
a-priori with potential value-added services help spur the discoveries of new 
tools, methodologies and innovative services.  Smart service systems span 
across a variety of socio-technical facets comprising of devices, people, 
organizations, environments, and technologies to sense, actuate, control and 
assess the physical, cyber and societal artifacts of the human service systems. 
Besides the systems being self-adaptive and fault-tolerant, need to be designed 
in such a way that it can continuously increase the quality and productivity, 
the compliance and sustainability of the smart services it offers. While 
human-centered perspective and cognitive learning help create multi-facet value 
added services and catalyze the sustained economic growth of smart service 
systems, understanding the multi-modal sensing, control, heterogeneity and 
interdependency between different physical, virtual and logical components of 
such a complex system will enable the realization of new transformative smarter 
service systems. If successful, this can help improve the quality-of-service of 
the customers, quality-of-life of the citizens and quality-of returns of the 
stakeholders and investors.

Nurturing the development of smart service systems seeks for inter- and 
trans-disciplinary crosscutting research threads from system and operational 
engineering, computer science and information systems, social and behavioral 
science, computational modeling and industrial engineering etc.  The goal of 
this workshop is to bring together practitioners and researchers from both 
academia and industry in order to have a forum for discussion and technical 
presentations on the fundamental knowledge and principles of  smart service 
systems that enable the value co-creation in sensing, actuating, data 
analytics, learning, cognition, and control of human centric 
cyber-physical-social systems.

Research contributions are solicited in all areas pertinent to smart human 
services and systems, including:

• Innovative tools, methodologies and solutions for smart service systems; 
example includes personalized healthcare, smart energy, smart cities, smart 
manufacturing, intelligent transportation, education, precision medicine and 
agriculture, national security etc.

• Information extraction and interpretation from sensors, actuators, smart 
phones, smart watch, and human

• Context and situational-awareness of smart service systems

• Design of people-centric services and technologies for providing better 
services such as food, transportation and places to live

• Novel architectures and interoperable solutions for internet of things

• Models and methodologies for designing systems of systems

• Big data analytics approaches for providing better customer services, and 
innovating new types of sustainable services

• Modeling, analysis, co-production, and co-evolution of human activity, 
behavior and interaction for the effective adaptation and percolation of 
longitudinal smart service systems

[Wien] Limit of RmtKmax

[Arena Konta]

Dear Wien2k Users,

How to check if my calculations are beyond "approximate numerical linear 
dependency"? The below calculations were converged with the criterion -ec 
0.01 and -cc 0.01 on a fine mesh k-point to determine a good Fermi 
level energy accuracy (simple mettalic 3D compound cointaining Y and Al 
elements). No warning in scf file is appeared. From RKmax>=10 onwards the 
change in energy differences is smaller than 0.0002 Ry, hovewer I have problems 
with convergation the value of the Fermi Energy. What should I do to obtain 
better accuracy of EF?

[visualization-api] Word Tree Separating into even sized Columns

[Louie Arena]

I've been working with a word tree for a while and I think an option to fix 
the words into columns would be a great update, also to decide what the 
width of each column would be. For example, I have a 6 column wide word 
tree and some branches of tree are shorter/longer than others. If there was 
a way to organize them all into columns so that each branch ended at the 
same length it would greatly improve the look and organization of word 
trees in my opinion. 

Does anyone know if there is a way to work around this?

Any suggestions would be greatly appreciated.

Thanks,

Louie

[Wien] Fermi energy & SO calculation

[Arena Konta]

Dear prof. Tran,

I appreciate your prompt response. I understand that the k-mesh for the band 
structure plot is not suitable for calculations of DOS.

Please, if I understand correctly:
If I increase the number of K-points, then for DOS we use Efermi from 
case.scf2? The same for Fermi surface calculation? And for Band Structure we 
always use :FER *scf -last value (from saved data)?

Thank you

Re: [Origami] Recreating Yoshizawa's unpublished models

[Xander Arena]

I'm glad I opened my O-list today, this has been an interesting thread.

I've been meaning to share a picture with you all for a few years and this
discussion has motivated me to do so. The picture is of a quickly folded
crane which I placed in a cabinet X-ray unit at a hospital I was
inspecting. This image does indeed show that it would be possible to
reconstruct anybody's models without actually deconstructing them.

Apart from gracious traveling displays, I think it would be really neat if
we one day saw large museums begin to collect these great works (not just
AY stuff) to display them alongside other artistic masters.

[Wien] maximum number of inequivalent k-points in case.outputkgen

[Arena Konta]

Dear Prof. Blaha and Dr. Kroeker

Thank you for your prompt responses and attached file. As suggested Dr. 
Kroeker, I increased the numbers in arbmsh.f. The stars  disappeared in 
outputkgen files. I also used the wien2k files attached by prof. Blaha and it 
works properly. However, I still have problems with xcrysden. When I increased 
both MAX_NKPT=99 and MAX_IRNKP= 2 in original wn_readbakgen.f file and 
I get ERROR: while executing wn_readbands program: Error Message: STOP NKP TOO 
SMALL. It seems this error I get when the Wien2k No. Of INEQIVALEN K-points is 
above  (in my case, for 200 000 k-points, I get 13776  No. Of INEQUIVALENT 
K-POINTS and the xcrysden ERROR, but for 140 000 kpoints with 9324 INEQUIVALENT 
k-points there everything is working properly). For the file attached by prof. 
Blaha, I get errors during compilation (without any changes inside):

gfortran -O2 -c wn_readbakgen.f
wn_readbakgen.f:110.33:

Re: [Wien] maximum number of inequivalent k-points in case.outputkgen

Peter Blaha Wed, 21 Dec 2016 03:34:38 -0800
I attach a few subroutines for SRC_kgen, which have been changed for larger 
formats. They should now not produce "***" up to 100 k-points.


The problem is, that for 1 000 000 k-points, you also have to change 
wn_readbakgen.f in xcrysden. (Or you do not change the "6000 format line" in 
reduz.f ( and stay at max 99 k-points.)


When it works, please let me know.

I've come to appreciate mixed media approaches to origami. To view origami
as art is to open it up to the flexibility of the creative process. I do
think it appropriate to reveal structural sequencing and methods,
particularly if one wants to take ownership in the design.

And speaking of cranes and atomic bombs, the city of Los Alamos, NM (where
the atomic bomb was developed) will be installing an origami crane
sculpture created by Kevin Box (with a little help from a friend ;o))
outside of their public library later this year. Here's a drawing showing
a mockup, and a photo of the crane sculpture in a different context:

If you get a chance to explore the museum, it's interesting to take note of

Scoop 1.4.5 on CDH 5.2.1 crashes when doing an incremental import to Parquet files

[Michael Arena]

Cloudera backported Parquet support to their version of Sqoop 1.4.5.

Originally, I was doing Sqoop incremental imports from SQL Server to text files 
(TSV).
This worked fine but the size and query speed of the textfiles are a problem.

I then tried importing as Avro files but Sqoop prohibits Avro and incremental 
mode.

I then tried importing as Parquet files.

The initial import worked fine and loaded 69,071 rows.
Then next time Sqoop ran, it pulled in the 1 changed row but then the merge 
step failed since it appears to think the files are text (not Parquet):

Re: Sqoop Incremental job does not honor the compression settings after the initial run

This seems like a bug. Which version of Sqoop are you using?

I am incrementally loading data from SQL Server to Hadoop using an Oozie Sqoop

Oozie runs a saved job in the Sqoop Metastore as created below:

   --meta-connect *** \
   -- import \
   --connect jdbc:sqlserver://mydbserver:1433;databaseName=mydb; \

   --last-value 1900-01-01 00:00:00.000 \
   --compress --compression-codec org.apache.hadoop.io.compress.SnappyCodec


The initial time the job runs, it creates 4 files like:
part-m-0.snappy
part-m-2.snappy
part-m-3.snappy
part-m-4.snappy

It did not need to do the merge step since there was no existing data.

However, the next time it runs, it pulls over modified rows from SQL Server and 
then merges them into the existing data and creates files:
part-r-0
part-r-1
part-r-2
...
part-r-00020
part-r-00031

which are uncompressed TSV files.


The Sqoop Metastore has the compression settings saved:
% sqoop job --show import__test__mydb__mytable
...
enable.compression = true
compression.codec = org.apache.hadoop.io.compress.SnappyCodec
...


Since the files are named part-m-X.snappy after the first run, I am 
guessing that the -m- in the name means the mappers created them (and also 
since I specified 4 mappers).

On the second run, I am guessing that the (32?) reducers created the output 
since there was merging necessary and the files have -r- in the name.

Is this a bug or expected behavior?
Is there some other settings to tell the reducers to honor the compression 
settings?
If it is a bug, where do I create an issue (JIRA) for it?

[Origami] NO - New Sighting?

[Xander Arena]

While driving back and forth from Colorado recently, I noticed many
Semitrailers with folding panels at their tail gate, clearly to reduce
drag. Has anybody noticed these panels? Made mention here?

It seemed like an ori-ish engineering application, so I thought I'd share.

 I've loaded the CA file into openssl.cafile php.ini but no workey.

how to
 get more debugging info in order to fix it?

 I'm using RC 1.0.4


 http://php.net//manual/en/migration56.openssl.php

 While not recommended in general, it is possible to disable peer
certificate verification for a request by setting the verify_peer context
option to FALSE, and to disable peer name validation by setting the
verify_peer_name context option to FALSE.



The setting openssl.cafile is meant to avoid disabling the check above.

In any case I found how to disable such settings for an IMAP connection,
but not for a CardDAV one.

Thanks.

[RCU] CARDDAV unknown SSL error

[Leonardo Arena]

Hi list,
I've recently upgraded to PHP 5.6 and this problem has shown up:

roundcube: cdfopen: Could not open: 0 could not connect to the host 
myhost.mydomain.me: stream_socket_client(): unable to connect to ssl://
127.0.0.1:443 (Unknown error)

I've loaded the CA file into openssl.cafile php.ini but no workey.

Could anybody shed some light on the nature of the error, or at least how
to get more debugging info in order to fix it?

I'm using RC 1.0.4

Thanks!

 Actually this save me from disabling only verify_peer. The cert name
 does not match because I mapped myhost.mydomain.me to 127.0.0.1 in
 the hosts file. I'll try removing it and see if that works.
 

Nope:

roundcube: cdfopen: Could not open: 0 could not connect to the host
opendrive.bsod.eu: stream_socket_client(): unable to connect to
ssl://IP_EDITED:443 (Unknown error)

Can anyone point me how to disable verify_peer_name in the context of
CardDAV connection (if this is the problem)?

Thanks!
