Hi, My emoncms feeds/inputs fail randomly. Sometimes it will run for 12+ hours, other times only 2 minutes. I have a system with the data being sent back to a raspberry pi as serial data, and when emoncms fails I can still see the pi receiving from the sensors using minicom.
I set up the pi to send to both local and remote emoncms, but they both stopped displaying updates this morning.
This is an error I captured from the pi:
Traceback (most recent call last):
File "/usr/share/emonhub/emonhub.py", line 336, in <module>
hub.run()
File "/usr/share/emonhub/emonhub.py", line 90, in run
values = I.read()
File "/home/pi/emonhub/src/emonhub_interfacer.py", line 368, in read
return self._process_frame(f, t)
File "/home/pi/emonhub/src/emonhub_interfacer.py", line 106, in _process_frame
frame = self._decode_frame(ref, validated)
File "/home/pi/emonhub/src/emonhub_interfacer.py", line 228, in _decode_frame
decoded.insert(0, int(node))
ValueError: invalid literal for int() with base 10: '.48'
My data is in node 10 with 5 values (4 CT one VT)
Can I view the local database to see the invalid value?
I have seen the notify module as an add on for emailing if feeds are down, can this be used to restart emonhub as well as email?
I also considered restarting thje pi once per day, but sometimes after a restart the feeds still won't work- so it takes two restarts.
Has anyone had a similar problem or could provide any advice?
Thanks,
David.
Re: Emonhub failing?
More testing using minicom I am pretty sure the emonhub service stops when minicom reports an incorrect line,
10 966.87 -534.54 0.29 -0.16 240.80 is the normal output, but when it crashes I had a line missing the node and the first 2 CT values
Originally I was using copper for the direct serial connection, but I have since replace that with a 433mhz wireless serial link.
Is it possible to make it discard this packet with missing data and continue?
Thanks
Re: Emonhub failing?
Hi David.
It indeed looks like incomplete data is the root problem and finding the cause of that should be the main focus.
There is no question emonhub should handle this exception far more gracefully and I can take a look into that, But while emonhub can do some integrity checks like check if a number is a float or within a range etc it can't totally validate all data, yes in the case of ".48" that obviously isn't an int so that packet could be discarded, but how many times has "10.48" been passed as 10 without a problem when it was intended to be 210.48 or -4410.48 ? If the "0.48" was discarded gracefully (as it should be) unless you check the logs regularly you are oblivious to a problem until you spot anomalies the data you are collecting.
Partial numbers are difficult to detect but partial frames can be a little easier. If you were receiving data in individual bytes and reconstructing to real numbers in emonhub, then a "datacodes" string could provide a fixed value count, but since you are receiving real values the "datacodes" decoding is not used so no checks are done. It may be handy if emonhub was able to use this to confirm the value count if demanded and I can look into that too, but this still wouldn't prevent partial numbers distorting the data.
How are you collecting data? what rf "system" are you using? the rf12's we use discard any incomplete packets so it's not something emonhub or other softwares need to worry too much about, hence the unnoticed "hole" :-)
Paul
Re: Emonhub failing?
Thinking about the value count, there is a possibility emonhub may be able to check this already if you put an entry in the [nodes] section of the conf eg
where each value is declared as a datatype "0". The "0" datatype was intended to tell emonhub not to decode real values and is the default datacode for all interfacers except the one for the RFM2Pi. Currently if you do not have any [nodes] data in the conf for node 10, emonhub will basically expect an unknown number of datatype "0" values, I haven't tried this, but in theory the string above will tell emonhub to "do nothing" for each of the 5 expected values and if there isn't 5 values to "do nothing" to, discard the frame. No guarantee it will work but there is a strong enough possibility it will work to justify trying it out.
if the frame is incomplete it should log a warning saying "RX data length: 4 is not valid for datacodes 0, 0, 0, 0, 0" for example if only 4 of the 5 expected are found.
A node id type check will be added when I get a mo to decide the best place for it and give it a test.
Paul
Re: Emonhub failing?
Hi Paul thanks for the reply,
I am using the Shield_CT1234_Voltage sketch with the output :
// Print to serial
Serial.print(nodeID); Serial.print(' ');
Serial.print(ct1.realPower); Serial.print(' ');
Serial.print(ct2.realPower); Serial.print(' ');
Serial.print(ct3.realPower); Serial.print(' ');
Serial.print(ct4.realPower); Serial.print(' ');
Serial.println(ct1.Vrms);
being sent to a HC-11 433Mhz Wireless to TTL CC1101 Module. This is then received by another of the same modules feeding the Rx pin on the R pi.
In the emonhub.conf I have hashed out the RFM2Pi and added a serial direct interfacer.
Nodes is set as:
# List of nodes by node ID
# 'datacode' is default for node and 'datacodes' are per value data codes.
# if both are present 'datacode' is ignored in favour of 'datacodes'
[[99]]
datacode = h
datacodes = h, f, f, f, f, f
Are you saying that if I use the interfacer for the RFM2Pi then the packets would be processed better?
Does datacode = h provide the best error checking, whereas I am using = h, f, f, f, f, f which is causing the errors, maybe the h could be a non numerical value to identify node and if it is not followed by 5 f values it discards all till a new h is received. using a non numerical h would remove errors where an f value could be mistaken as the h to start the packet?
David.
edit: sorry typed the above before reading your last post, I have just changed the conf file to replace the datacodes f with 0, will let you know the results.
Re: Emonhub failing?
Hi David,
I'm not familiar with the rf devices you are using but I gather the sketch is just "printing" real human readable values which are then repeated via rf to the serial gpio, so I expect the "normal output" like that in bold in the 2nd post is exactly as you see in minicom. Therefore the values do not need decoding and are dealt with by emonhub's default "0" datatype.
The hypothetical (out of range) node [[99]] in the conf was just an example template and changing the datacodes as you had will not of had any effect (unless you actually have a node 99 of course) I note you had used datacodes h, f, f, f, f, f to include the node id the datacodes are actually a template or key to decode just the data so the h wasn't required even if the f's had been correct for the data.
Up until now the node ids have only been numbers and more specifically usually between 1 and 31, and is not intended to process anything non-numeric (yet) and I think the "0" datatypes may provide a check for incomplete packets.
The correct interfacer to use is indeed the serial interfacer, the RFM2Pi 'Jee' interfacer is too tailored to the RFM2Pi to work with what you have.
Lets see how or if the "0" datacodes help and with a better node id test you should be good.
Paul
Re: Emonhub failing?
Hi,
I worked for a while, but broke again. Initially when I changed the conf file I restarted the Pi. Maybe I did not wait long enough, but the local emoncms did not start updating feeds. I tried to start it manually but ended up with a few errors- different things already started or failed to start?
Anyway eventually I got it all going for maybe 8 hours, it seemed to handle "bad packets" without causing the emonhub service to stop. When I woke this morning it had already failed, then after 2 hours it failed again, each time requiring restart of the service.
These are the last two error logs:
2014-12-22 15:44:50,079 WARNING 493 Discarded RX frame 'non-numerical content' : ['\xa6\xa6\x02j\x82r\x82\x92\x02\x92\xa2\x92r\x92\xc2j\n10', '1319.71', '-751.36', '0.41', '0.57', '242.27']

I do notice that I have alot more inputs now, 2 from each node 4, 5, 7 and 14. and key 6, 7, and 8 from my normal node 10 have values 21 hours old?
I have left another putty session open to constantly watch the minicom events
edit: failed again and the only irregularity I can see in minicom is

That node 5 with 2 values
Restarted emonhub twice, did not help so restarted pi- all good again
Re: Emonhub failing?
It's quite difficult to tell what's happening without the full picture, but reading between the lines a little here and there, I can see the issues definitely need tackling before emonhub.
The "last two error logs" tells us firstly that emonhub handled those bad packets by recognizing the "flaw" and discarding them with a error message, it also tells us that is not the cause as emonhub continued to function after the first to report the second. Then theres the content which is not "incomplete" or even just 2 messages amalgamated, they contain raw hex passed as a string too.
Old Inactive inputs on node 10 is a good sign as that suggests the "0" datacodes are doing their bit and only "5 value" node 10 frames are getting through.
If you are seeing "alot more inputs now" that may be a good thing by filtering more out, more is getting through. But it suggests how "random" the resulting data might be as only the node id irregularities are highlighted by creating an extra node. Something else to consider is emoncms discards any frames that have a node id outside the range 0-32 so how many other inputs would be created if that wasn't the case is not known.
The "node 5 with 2 values" is just half a packet and would of been passed to emoncms as normal, emonhub has no way of knowing it's not genuine.
The fact that restarting emonhub doesn't clear the problem every time actually suggests something else is at fault.
emonhub is designed to catch the occasional fault rather than pick out good packets from a unmanaged stream, Tackling this is maybe a good exercise for the development of emonhub as it is testing the error handling to an increased level, this can help emonhub become more robust, but from your point of view the more it discards and filters out, the less data you're left with and with a high probability of error in the remaining the data, it will at best be inconsistent and therefore unreliable and possibly misleading information. It would take far less effort and yield much better results to tackle the issue at source.
This probably isn't what you want to hear but I think you should reconnect using a direct wired connection and if all is well, then look at improving the wireless link either by building on what you have or switching to a known good rf link. The rfm2pi board is relatively cheap and a rfm12 or rfm69 will drop straight onto the shield.
Paul
Re: Emonhub failing?
Just to clarify, I'm not suggesting emonhub is without fault. We have clearly already identified that if a non-numeric node id including a partial number eg ".2" (decimal point but no leading digit) will cause emonhub to fall over and that needs to be and will be addressed and that may well improve things a little for your data. But I'm very aware that emonhub is unlikely to be able to condition the current input stream to make it credible enough.
Paul
Re: Emonhub failing?
So i started looking into the above "non-numeric node id" issue and have found it would be caught by the recent change made to catch empty frames. Similarly the empty frames shouldn't of reached emonhub but that doesn't mean emonhub should be vulnerable to such occurrences.(see issue for more info).
I have now merged those changes from the "testing" branch so if you update emonhub to rc1.2 using a git pull we can eliminate those errors causing emonhub to fail.
Paul
Re: Emonhub failing?
Hi Paul, thankyou for all your help so far. I will update emonhub soon and see how much it improves, and will see if I can reconnect the serial link with copper. That will be a bit involved since they are each installed in position. The raspberry pi will probably have to be moved closer to the switchboard but it will be good to remove the wireless link to help isolate my fault(s)

Re: Emonhub failing?
Hi David, not sure why but those logs point to an issue at the emoncms end. the request is timing out before emonhub is getting the "ok" response it expects.
Re: Emonhub failing?
are you posting to emoncms.org? there is an intermittent load issue on emoncms.org at the moment that may cause the timeout, that would affect a couple of posts every now and then while receiving most of them correctly.
Re: Emonhub failing?
Hi, yes I am posting to emoncms.org and to the local RPi.
Prior to today I had about 3 days of uninterrupted data. Pretty sure this lined up wtih upgrading emonhub to version 1.2 Thankyou for your good work on that Paul. My log file was still showing errors- unable to send to server, non numerical, string too short and I think a node id error. But it kept running and processing what it could.
Todays fault was something in the switchboard but it is all running fine again.

The above error, similar to what we have seen from my system before does not seem to be created by my wireless link for a serial connected system. A friend tried a setup with a different sketch modified for serial but was using a copper link for the transmit to the RPi and was getting similar garbage in his log.
Maybe some other direct serial users could provide feedback, although the newer emonhub does not seem troubled by it.
Also is Emoncms configurable so it logs my 24hour time period for accumulated data? My daily totals seem to turn up maybe in line with your midnight? Which means the totals do not match my inverter.
Thanks
Re: Emonhub failing?
Good to hear you've made some progress. The log excerpt shown includes a string of hex control codes and as it was the first line read it maybe it is some set up data from the rf module perhaps. Do you see these anomalies in minicom too?
Paul
Re: Emonhub failing?
Hi, I did not have an instance of minicom running at the time, but I have seen it a bit in the emonhub log file. I thought maybe it was my garage door remote, but I could not reproduce it. Possibly something from the neighbours devices.

Prompt cusps of the first halos
[More detail] [Outreach article]
When gravitational collapse breaks the smooth mass distribution of the early universe, the process immediately produces a compact structure in which density scales with radius as ρ ~ r^-1.5 (see this video). I find no evidence that these prompt density cusps are destroyed as the halos around them grow. Since every halo and subhalo in the universe formed from an initial gravitational collapse event, this result suggests that a prompt cusp should reside inside every one of them. This outcome has significant observational consequences for cold and warm dark matter models.
Stochastic gravitational influence of dark halos
[More detail]
Dark matter halos are known to surround galaxies, but the vast majority of halos are expected to be devoid of stars and gas, so they are difficult to detect. However, they can perturb the motions of stars, dynamically heating stellar systems and producing characteristic patterns in stellar positions and motions. I derived an analytic framework that connects the statistical properties of a gravitationally perturbed stellar system to those of its dark halo perturbers.
Formation of halos prior to the matter epoch
[More detail]
If initial variations in the density of the universe are sufficiently extreme at small scales, dark matter halos can form prior to the matter-dominated epoch, which began at a time of about 52000 years. I found that while gravitationally bound structures cannot form where radiation dominates, convergent particle drift can cause localized regions to become matter dominated and form bound halos long before radiation globally gives way to matter. These haloes would be around a trillion times more internally dense than the halos that surround galaxies.
Probing the early universe using dark matter minihalos
[More detail]
The first gravitationally bound objects in the Universe were small, potentially Solar System–scale dark matter minihalos. These objects are broadly expected to survive today, and their potentially observable characteristics represent a probe of the primordial mass distribution at otherwise inaccessibly small scales. Consequently, they represent a unique probe of the late stages of inflation and the early postinflationary period. I use N-body simulations and mathematical modeling to decipher the connection between minihalos today and primordial cosmology.
Predicting populations of dark matter halos
[More detail]
All cosmic structure grew out of initially minor variations in the density of the Universe. This structure manifests visibly as galaxies, but it is dominated by invisible dark matter. Dark matter clusters into gravitationally bound halos that represent the building blocks of structure. The problem of predicting a halo population from the precursor mass distribution is a longstanding one, but I am developing new ways to approach this problem. My approach begins with the first halos, following their evolution as they cluster to produce later generations of halos.

Hello!
I've just built a modified version of the EmonTX with a custom pcb for measuring the charging voltage/current from a solar cell to a battery and for the current from the battery going to a load using two different ACS712 sensors (5A for charge and 30A for discharge) and a voltage divider. There is also a connector for DS18B20 sensors for later use and connectors for the unused pins of the processor
I used the standard EmonTX firmware and modified the needed parts: deleted the part with the CT, added DC voltage measurement with 3 channels. Everything is looking good via the serial connection, I get the voltage and current readings, even the LED blinking every few seconds, but I don't receive any data on my raspberry.
The raspberry itself is working fine, actual data from 2 other EmonTX is received.
I also checked the wireing and solder connections between the ATMEL and the RFM12 but couldn't find any problem.
Is there a software to test if the processor <=> RFM12 connection is working correct, maybe a self-test function of the RFM12 that sends back information to the processor if the module is ok or not ok?
best regards
Juergen Brenner
Re: Software to test RFM12
I am not aware that there is a self-test.
I assume you have tried using a sketch that is known to work with the other emonTx's (OK, I know the data will be wrong but if anything gets through...).
"even the LED blinking every few seconds" That indicates that it is not hanging, so it appears to be accepting the instructions?
In cases like this where you think you have checked everything, my usual advice is to go back and carefully check the things that are so simple and obvious that they could not possibly be wrong ;-)
Finally, you might find some information over at JeeLibs. There are many example sketches in the JeeLib library that might be helpful.
Re: Software to test RFM12

http://openenergymonitor.org/emon/node/2084
Re: Software to test RFM12
Hello!
I checked again everything, it is still not working now but I've got a possible reason: the RFM12 modules I get some days again are 433MHz instead of the orderd 868Mhz version. I hope this is the only problem, but I will know if this is the solution when I get the correct modules.
For the future: always check the frequency of the modules before installing them into a pcb, removing is no fun.
best regards
Re: Software to test RFM12
I believe there's a subtle difference in their appearance. The 868 MHz ones that I've always use have a couple of unsoldered pads on them. So if they look different, they probably are ...

The C++ implementation can be compiled with emscripten to produce a Javascript implementation of Jsonlang. This is how we implement our Jsonlang demo. It is not the fastest possible Javascript implementation of Jsonlang, but it is easy to build, and is sufficient for many purposes.
To compile it, first install emscripten and ensure em++ and emcc are in your path. Then make libjsonlang.js.
An unofficial nodejs package of Jsonlang is also available.

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/Thunderbird
The build process for Thunderbird can use 8GB+ of RAM when linking. Make sure that you have adequate swap or RAM before continuing.
The configuration of Thunderbird
is accomplished by creating a mozconfig
file containing the desired
configuration options. A default mozconfig
is created below. To see the entire
list of available configuration options (and a brief description of
each), issue mozilla/configure
--help. Create the file with the following command:
cat > mozconfig << "EOF"
# If you have a multicore machine, the build may be faster if using parallel
# jobs. The build system automatically adds -jN to the "make" flags, where N
# is the number of CPU cores. The option below is therefore useless, unless
# you want to use a smaller number of jobs:
#mk_add_options MOZ_MAKE_FLAGS="-j1"
# If you have installed dbus-glib, comment out this line:
ac_add_options --disable-dbus
# If you have installed wireless-tools comment out this line:
ac_add_options --disable-necko-wifi
# Uncomment these lines if you have installed optional dependencies:
#ac_add_options --enable-startup-notification
# Comment out following option if you have PulseAudio installed
ac_add_options --disable-pulseaudio
# Comment out following option if you have gconf installed
ac_add_options --disable-gconf
# If you want to compile the Mozilla Calendar, uncomment this line:
#ac_add_options --enable-calendar
# Comment out following options if you have not installed
# recommended dependencies:

ac_add_options --with-system-libevent
ac_add_options --with-system-nspr
ac_add_options --with-system-nss

# The elf-hack causes failed builds on clang-9.0.1 with some CFLAGS including

Compile Thunderbird by issuing the following commands:
If you are compiling Thunderbird
in chroot, prepend SHELL=/bin/sh
to
the build command below.
./mach build
This package does not come with a test suite.
Install Thunderbird by running the
following commands as the root
user:
./mach install
./mach build: Thunderbird now uses this python2 script to run the build and install.
./mach build --verbose
: Use this
alternative if you need details of which files are being compiled,
together with any C or C++ flags being used.
If your Window or Desktop Manager does not allow you to configure a default browser, you can add a configuration parameter to Thunderbird so that a browser will start when you click on an Internet/intranet/local URL. The procedure to check or modify any of the configuration parameters is quite simple and the instructions here can be used to view or modify any of the parameters.
First, open the configuration dialog by opening the “Edit” drop-down menu. Choose “Preferences” and then click on the “Advanced” icon on the top menu bar. Choose the “General” tab and click on the “Config Editor” button. This will display a list of the configuration preferences and information related to each one. You can use the “Filter:” bar to enter search criteria and narrow down the listed items. Changing a preference can be done using two methods. One, if the preference has a boolean value (True/False), simply double-click on the preference to toggle the value and two, for other preferences simply right-click on the desired line, choose “Modify” from the menu and change the value. Creating new preference items is accomplished in the same way, except choose “New” from the menu and provide the desired data into the fields when prompted.
The configuration preference item you need to check so that
Thunderbird uses a specified
browser is the network.protocol-handler.app.http
which should be set to the path of the desired browser, e.g.
/usr/bin/firefox
.
There is a multitude of configuration parameters you can tweak to customize Thunderbird. A very extensive, but not so up-to-date list of these parameters can be found at http://preferential.mozdev.org/preferences.html.
If you use a desktop environment such as GNOME or KDE, a desktop file thunderbird.desktop
may be created, in order to
include a “Thunderbird” entry in
the menu. If you didn't enable startup-notification in your mozconfig, then
change the StartupNotify line to false. Run the following
commands as the root
user:
mkdir -pv /usr/share/{applications,pixmaps} &&
cat > /usr/share/applications/thunderbird.desktop << "EOF" &&

Package org.jboss.stm.async

- org.jboss.stm.async.Transaction

public class Transaction extends java.lang.Object
This is a user-level transaction class. Unlike AtomicAction which it uses, this provides an asynchronous begin, commit and rollback capability. There are a number of ways in which we currently support asynchronous interactions with the transaction system, such as async prepare or async commit. The developer could also register a two-phase aware participant or a Synchronisation and use callbacks themselves to determine the outcome of the transaction. These continue to be available to the developer but this API is intended to provide a simplified interface to allow clients to make use of asynchronous transactions. Note, we deliberately don't derive from AtomicAction so that developers must make a conscious choice between a synchronous or asynchronous transaction.- Version:

Constructor Detail
-
Transaction
public Transaction()
Create a new transaction. If there is already a transaction associated with the thread then this new transaction will be automatically nested. The transaction is *not* running at this point. No timeout is associated with this transaction, i.e., it will not be automatically rolled back by the system.
-
Transaction
public Transaction(Uid objUid)
AtomicAction constructor with a Uid. This constructor is for recreating an AtomicAction, typically during crash recovery.
-
-
Method Detail
-
begin
public java.util.concurrent.Future<java.lang.Integer> begin()
Start the transaction running. If the transaction is already running or has terminated, then an error code will be returned. No timeout is associated with the transaction.- Returns:
ActionStatus
indicating outcome.
-
begin
public java.util.concurrent.Future<java.lang.Integer> begin(int timeout)
Start the transaction running. If the transaction is already running or has terminated, then an error code will be returned.- Parameters:
timeout
- the timeout associated with the transaction. If the transaction is still active when this timeout elapses, the system will automatically roll it back.- Returns:
ActionStatus
indicating outcome.
-
commit
public java.util.concurrent.Future<java.lang.Integer> commit()
Commit the transaction, and have heuristic reporting. Heuristic reporting via the return code is enabled.- Returns:
ActionStatus
indicating outcome.
-
commit
public java.util.concurrent.Future<java.lang.Integer> commit(boolean report_heuristics)
Commit the transaction. The report_heuristics parameter can be used to determine whether or not heuristic outcomes are reported. If the transaction has already terminated, or has not begun, then an appropriate error code will be returned.- Returns:
ActionStatus
indicating outcome.
-
abort
public java.util.concurrent.Future<java.lang.Integer> abort()
Abort (rollback) the transaction. If the transaction has already terminated, or has not been begun, then an appropriate error code will be returned.- Returns:
ActionStatus
indicating outcome.
-
getTimeout
public final int getTimeout()
-
type
public java.lang.String type()
The type of the class is used to locate the state of the transaction log in the object store. Overloads BasicAction.type()- Returns:
- a string representation of the hierarchy of the class for storing logs in the transaction object store.
-
suspend
public static final Transaction suspend()
Suspend all transaction association from the invoking thread. When this operation returns, the thread will be associated with no transactions. If the current transaction is not an AtomicAction then this method will not suspend. Note, we do not provide an async version of suspend because it would be wrong for an application thread to proceed under the assumption it had succeeded/happened yet. Ordering of events makes a difference here.- Returns:
- a handle on the current AtomicAction (if any) so that the thread can later resume association if required.
-
resume
public static final boolean resume(Transaction act)
Resume transaction association on the current thread. If the specified transaction is null, then this is the same as doing a suspend. If the current thread is associated with transactions then those associations will be lost. Note, we do not provide an async version of resume because it would be wrong for an application thread to proceed under the assumption it had succeeded/happened yet. Ordering of events makes a difference here.- Parameters:
act
- the transaction to associate. If this is a nested transaction, then the thread will be associated with all of the transactions in the hierarchy.- Returns:
true
if association is successful,false
otherwise.

PyOnly lets you build interactive web UIs using Python instead of JavaScript. It enables you to deploy machine learning applications because existing libraries such as TensorFlow can be used. PyOnly works without plugins or code transpilation in all modern web browsers, including mobile browsers. The client logic runs on the server and the required UI changes are sent to the client. The best thing is you don't have to jump between client and server code. Both are in the same script!

The eq
method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on
non-null instances of AnyRef
:
* It is reflexive: for any non-null instance x
of type AnyRef
, x.eq(x)
returns true
.
* It is symmetric: for any non-null instances x
and y
of type AnyRef
, x.eq(y)
returns true
if and
only if y.eq(x)
returns true
.
* It is transitive: for any non-null instances x
, y
, and z
of type AnyRef
if x.eq(y)
returns true
and y.eq(z)
returns true
, then x.eq(z)
returns true
.
Additionally, the eq
method has three other properties.
* It is consistent: for any non-null instances x
and y
of type AnyRef
, multiple invocations of
x.eq(y)
consistently returns true
or consistently returns false
.
* For any non-null instance x
of type AnyRef
, x.eq(null)
and null.eq(x)
returns false
.
* null.eq(null)
returns true
.
When overriding the equals
or hashCode
methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2
), they
should be equal to each other (o1 == o2
) and they should hash to the same value (o1.hashCode == o2.hashCode
).

This method is used to compare the receiver object (this

The default implementations of this method is an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence

if x.equals(y)
returns true
and
y.equals(z)
returns true
, then x.equals(z)
should return true
.
If you override this method, you should verify that your implementation remains an equivalence relation.
Additionally, when overriding this method it is often necessary to override hashCode
to ensure that objects
that are "equal" (o1.equals(o2)
returns true
) hash to the same
scala.Int
(o1.hashCode.equals(o2.hashCode)
).

US all the way on Friday night with Treasuries, the USD Index and Wall Street all advancing in tandem on the back of (spurious) claims by Trump that the US/China trade talks are advancing well – even though he later contradicted that in a Fox news rant. In Europe, new ECB President Lagarde made her first speech which gave European stocks a slight boost, even though the series of EU and UK flash PMIs disappointed as Brexit concerns continue to weigh.

Police to increase London patrols during Road Safety Week
by Kenneth BrownTransport for London (TfL) and the Police are marking Road Safety Week by taking increased action to reduce road danger, aiming to reduce accidents and deaths.
They are taking part in targeted high visibility and covert policing patrols on London’s roads, in order to reduce careless driving and well as educating all road users.
The new initiative, called ‘Travel Safe Priority Areas’, aims to tackle community road safety issues over a short duration.
This also includes high visibility and covert policing, community and junior roadwatch sessions, where members of the public work with the police to educate drivers about the dangers of speeding and communicating more information about road safety.
Stuart Reid, director of vision zero at TfL, said: “People are dying on our streets every week from avoidable road collisions and Road Safety Week provides us with an opportunity to remind ourselves of the importance of reducing road danger for all.
“By working closely with the police, lowering speed limits, responding to specific community concerns and more, we hope to save lives.”
The trial is taking place in Shoreditch and Camden.
TfL and the police are also working to lower speed limits to 20mph in central London, with other key areas to have their speed limits lowered by March 2020.
They’re also working to remove the most dangerous lorries from London’s roads with the direct vision standard.
It aims to eliminate dangerous heavy goods vehicle (HGV) blind spots.
Those that do not comply from October 2020 will be issued a penalty charge.
In 2018, 112 people were killed because of road accidents, with a further 3,954 suffering injuries on London’s roads.
Police sergeant Nina Houghton-Worsfold, from the City of London Police, said: “Protecting all road users is of the upmost importance to the City of London Police and something we focus on day in day out, alongside our partners, to achieve the aims of Vision Zero.
"Road Safety Week is another opportunity for us to educate road users and pedestrians of the risks to themselves and others associated with irresponsible and dangerous behaviour such as speeding, using mobile phones and disobeying traffic lights and other road signals.”


When: Monday, Wednesday, Friday from 8:00pm to 9:30pm
How much: $50 per half semester; first two weeks are free

Yiddish author monument vandalized with swastikas in Ukraine
by The Associated PressKYIV, Ukraine (AP) — Unidentified vandals have painted swastikas on a monument to a prominent Yiddish author in the Ukrainian capital.
Moshe Reuven Azman, the chief rabbi of Ukraine, posted pictures Monday of the monument to Sholem Aleichem outside Kyiv’s synagogue with big red swastikas spray-painted on it.
Police have opened a probe.
In a tweet, Foreign Minister Vadym Prystaiko denounced the anti-Semitic act as “disgusting, appalling and in need of prompt investigation.”
Israeli Ambassador Joel Lion tweeted that “Ukraine has to wake up,” urging authorities to track down the culprits, bring them to justice and also “educate against hatred.”
Ukraine has seen numerous cases of vandalism at Jewish cemeteries and Holocaust memorials across the country. Hateful graffiti has also been painted on synagogues and Jewish institutions across the country.

Validation Comparison
User Data Upload
This page contains a quick user tutorial. More comprehensive information can be found in our User Manual.
The validate page is subdivided into areas for the various validation parameters. Each area has menu with two icons on the top right. Hover over the question mark to get help for the respective areas. You can use the +/- icon to fold up or fold down the area.
Step 1 - Choose the data you would like to validate - including the dataset name, the version of the dataset, and one of the soil moisture variables provided in the dataset. All the supported datasets are listed on datasets page here. Plase note, that there have to be at least two datasets added, as one of them will be treated as the reference one.
Step 2 [optional] - Choose the criteria by which you would like to filter this dataset. The filters available depend on the data contained within the chosen dataset. For example, you can filter the C3S data to include only data with variable in valid geophysical range. Details of the filter options provided for each dataset are given on the supported datasets page. You can also hover your mouse pointer over the question mark next to a filter to get a short explanation.
Step 3 [optional] - If you want to intercompare several datasets, you can add more datasets to the validation
using the Add dataset button, up to a maximum of six. Configure the settings for the additional datasets by
selecting
the respective tab and repeating steps 1 and 2 above.
Intercomparison: The intercomparison mode of QA4SM validates up to six satellite data sets against a common spatial reference data set. For each reference location (e.g. each ISMN station) it finds the nearest observation series in all selected satellite products. All observations series are then scaled (if selected) and temporally matched to the temporal reference series. For validation only the common time stamps (that are available in all satellite products) are used to calculate validation metrics between the reference and each individual satellite product. This way deviations in the metrics due to different temporal coverage are excluded and validation results represent differences in the performance of the compared satellite products.
Step 4 - Choose which dataset selected for validation should be used as the spatial and temporal reference. Please note, that if the ISMN dataset belongs to the pool, it is set as the spatial reference automatically and there is no possibility of changing it.
Step 5 [optional] - If the ISMN belongs to the dataset pool you can also choose specific networks and/or measurements in a defined depth range. To do that you have to open an appropriate window by clicking a 'select...' link next to the filter you want to parameterised.
The window for choosing networks contains a list of continents. When clicking an arrow next to a continent name a list of networks that belong to the continent unfolds. Next to each network there is the name of the country it belongs to. To toggle the particular network it is enough to click on its name. The choice doesn't have to be approved, it is enough to close the dialog window and the choice will be saved.
The window for the depth selection contains two fields for introducing the depth range. Values have to be introduced in meters.
The choice can to be accepted by clicking the 'OK' button or simply by closing the dialog window.
Details of the filter options provided for each dataset are given on the supported datasets page
here. You can also hover your mouse pointer over the question mark next to a filter
to get a short explanation.
Step 6 [optional] - If you want to calculate metrics from anomalies instead of absolute values, select the desired method in the "Method" drop-down menu. The options are:
Step 7 [optional] - Chose the geographic area over which the validation should be performed. You can either
specify a lat/lon bounding
box directly or you can select the area on a map. The trash button will clear all four
bounding
box fields.
If you don't specify an area, a global validation will be done.
Step 8 [optional] - Choose the date range over which the validation should be performed and temporal matching
window size.
The only accepted date format for the validation period is: YYYY-MM-DD. It is also possible to choose a date from
a calendar, available when clicking the date input field. By default, the date range is determined through temporal
matching of the data and reference selected.
If the validation period fields are left empty, the validation will not be started. For the time range covered by
the various
datasets, see the datasets page.
For temporal matching window size, the default (and recommended) value is 12 hours and possible choices are integer
numbers between 1 and 24 hours.
Step 9 [optional] - Activate Triple Collocation Analysis (TC) and Bootstrapping Triple Collocation confidence
intervals (BTC). By default, QA4SM calculates validation
metrics between dataset pairs (the reference and each candidate data set). If more than 3 datasets
are selected (including the reference), the switch to activate TC becomes available. If
TC is selected, in addition to the basic metrics between dataset pairs, TC metrics between
triples of selected datasets are calculated. The reference is included in all triples and
metrics are found for all candidate datasets. Note that each TC metric is specific to a dataset
(this is evident from the metric name). TC metrics are affected by all 3 used datasets. Only results from TC with
independent datasets should be used.
The bootstrapping option is enabled only if TC is selected.
When it is chosen confidence intervals are calculated via bootstrapping with 1000 repetitions, however the
validation time might be up to 5 times longer.
Step 10 - Choose how the data will be scaled before metrics calculation. The data can be scaled to any dataset selected for validation. The scaling method determines how values of one dataset are mapped onto the value range of the other dataset for better comparability. Note that if the chosen method is 'No scaling', there is no scaling reference drop down list available.
Step 11 - Optionally name your validation results to make it easier to identify it in the list of all your validations.
Step 12 - Run the validation process. You'll be notified via e-mail once it's finished. You don't need to keep the results window (or even your browser) open for the validation to run. The email will contain a link to your results.
The list shows all your validations, including the currently running ones, sorted by date (latest first).
Note: Your validations will be automatically removed {{ this.getExpiryPeriod() }} days after completion by our auto-cleanup process, unless you extend or archive them. You will be warned via email about validation expiry {{ this.getWarningPeriod() }} days before deletion.
The icons in the validations' title bars indicate the following:
The buttons on the right-hand side of each validation have the following effects:
Once the validation process is finished, you can see a summary of the validation run on the results page.
The buttons at the bottom of the result overview have the following effects:
The following metrics are calculated during the validation process:
| Name | Description |
|---|---|
| Pearson's r | Pearson correlation coefficient |
| Pearson's r p-value | p-value for pearson correlation coefficient |
| Spearman's rho | Spearman rank correlation coefficient |
| Spearman's rho p-value | p-value for Spearman rank correlation coefficient |
| Root-mean-square deviation | Root-mean-square deviation |
| Bias (difference of means) | Average Error |
| # observations | Number of Observations |
| Unbiased root-mean-square deviation | Unbiased root-mean-square deviation |
| Mean square error | Mean square error |
| Mean square error correlation | Mean square error correlation |
| Mean square error bias | Mean square error bias |
| Mean square error variance | Mean square error variance |
| Residual Sum of Squares | Residual Sum of Squares |
| TC: Signal-to-noise ratio | TC: Signal-to-noise ratio |
| TC: Error standard deviation | TC: Error standard deviation' |
| TC: Scaling coefficient | TC: Scaling coefficient |
Visualisations of these metrics are displayed in the Result Files section of the page: boxplots and
geographical
overview maps. You can select the metric shown with the left drop-down button below the graphs.
For an intercomparison validation, all boxplots are combined into one graph. The dataset displayed in the overview
map can be selected with the drop-down button on the right.
You can also download a zipfile of all the plots in png and svg (vector) format by clicking on the Download all
graphs button, and the result NetCDF
file
with all metrics with the Download results in NetCDF button.
This feature allows you to publish the result NetCDF file of your validation to Zenodo under your own name but without creating your own Zenodo account. This gives you a DOI for your results, which you can cite in your publications to give your readers open access to your data.
Once you click the Publish button on the validation result page, you will
be presented with a dialog
containing the metadata the results will be published with. You can change the metadata to your liking (within
some limits) and start the file upload to Zenodo by clicking Publish
results.
Note that we require 'qa4sm' to be one of the keywords, and that Title, Description, Keywords, and
Name are mandatory fields. You don't need to give an affiliation or
ORCID, though. Changes you make to your
author details will not be stored to your user profile - for that, please
got to the Profile page.
The upload can take a few minutes, please be patient. If it should fail, please try
again a few hours later. If it still doesn't work, please email us at {{ this.getAdminMail() }} and include the
error message
you received.
Please be aware that the NetCDF file and the metadata will be stored at Zenodo under the account of the QA4SM
project but with your name as the author. Zenodo is a separate website run at CERN over which the QA4SM team
has no control.
Assigning a DOI to a result also means that it cannot easily be unpublished or
deleted - see also Zenodo's FAQ.
If you prefer to use your own Zenodo account, you can of course do so - the QA4SM publishing feature is just
for convenience. Just download the NetCDF result file and upload it yourself through Zenodo's submission process
with your own account. We'd ask you to use 'qa4sm' as one of the keywords so that we can easily find all QA4SM
results on Zenodo with a keyword search.
The list shows validations on the QA4SM service that have been published to Zenodo by their owners. This means the results can be cited with a DOI.
If you want to email us to send comments, report errors, or ask questions, you can do so at {{ this.getAdminMail() }}.
With the QA4SM version 2.1 (and later) it is possible to compare existing validations that belong to the currently logged-in user or have been published. The comparison module is available for a logged-in user under the “Compare validations” button in the navigation bar.
The module enables two comparison modes - a comparison of two validations with the same reference data set and one non-reference dataset or a comparison between two non-reference datasets used in one validation. The module consists of three main components: Dataset Configuration, Validations selection and Spatial extent (see pictures below).
The Datasets configuration component enables choosing the dataset that was used as the reference one (including its version and the variable name) and selecting the comparison mode. Checking ‘Multiple non-reference datasets’ switches on the ‘one validation’ comparison mode.
The Validations selection component gets updated with every change of the reference dataset and shows validations available for comparison. A selected validation has to be added by clicking the ‘Add validation’ button. If the maximum number of validations has been added, the ‘Add validation’ button gets disabled. Added validations are listed below the selection box as red ‘Remove validation’ buttons. Clicking a remove button will remove the appropriate validation from the list.
In general it is possible to compare any two validations that have the same reference dataset. If additionally the two validations have a common spatial extent, a user can choose if the comparison should be performed on all points or only on the common ones. If validations have no common points, the option ‘Include all points...’ is disabled.
The comparison is started by clicking the ‘Compare’ button. As a result users get four components:
All the plots and the statistics table can be downloaded using appropriate buttons placed next to each object.
Please note, that since the comparison module is still being developed and the comparison is done on the fly, there is a risk that a particular comparison may not be performed due to too big validation results file. If that is the case the user is advised to run smaller (in terms of spatial subsetting) validations and compare them one more time.
To upload your go to 'My datasets' page, by clicking proper button on the navigation bar.
Click the 'Select file' button, and then choose 'Add file' to add the file you want to upload. Note, that you'll be able to choose only .netCDF or .zip files, both types need to follow the standard described here. If the .zip file you are trying to upload contains other types of files than .netCDF, .csv or .yml, you will not be able to upload the file. Please note, that you have 5GB space available for your files. In case you need more, please contact our team.
When you choose proper file, a form for providing metadata will show up. You need to provide dataset and version names. Additionally you can introduce display names for both dataset and its version, which is going to be used on the list of available datasets. If the display name is not provided, the basic name is going to be used.
If you want to change file, you can do it by clicking 'Change file' button. If you want to save provided information, click 'Save' button. Clicking 'Save' button will close the metadata form, but won't start uploading yet. To start uploading, click the 'Upload file' button.
Depending on the file size and your upload speed it may take from few seconds up to tens of minutes. You will see a blue spinner and information about the percentage of uploaded file. Eventually an information will show up that the file has been uploaded, but it still needs to be pre-processed.
When the file gets uploaded and preprocessed, there will show up a row with basic information on the uploaded file. You'll be able to change the dataset's name, the version's name and choose a different variable, if the default one is inproper or we were not able to retrieve the proper name. By clicking 'Remove dataset' button, you will remove the uploaded file. Note, that removing is possible only if the uploaded data hasn't been used for any validation.
If you want to use your dataset in a validation, simply go to the Validate page and expand the dataset dropdown list. Your dataset will be there.
Now you can choose other settings and run a validation. Note that for now it is not possible to publish validation that uses private data. You can still share your validation with another user, but they won't be able to rerun it, as they don't have access to your dataset.


Practical Threat Modeling
NOTE: This chapter is currently in progress. It’s being posted for peer review during the writing process.
Threat modeling is the art of thinking about what threats your application will face. By understanding the threats, you can begin thinking about how to mitigate them.
One useful tool when threat modeling is an attack tree. In an attack tree, you identify what threats you might face, and what those attacks lead to. During the initial stages, you don’t focus on mitigation (or what you have done so far). It’s important to consider what sorts of attacks can be made: while you might think an attack is mitigated or you may not see it as practical, changes to the code can easily change the situation. It’s important to regularly review the attack tree, updating it as necessary. If you add a feature, consider the potential security impact. The point of the attack tree is just to visualise what could happen; later parts of the security engineering process transform this into a practical outlook.
Let’s consider a simple web site that allows users to update their information; it’s backed by a fairly simple database. Some potential attack vectors that come to mind in a quick overview are:
- SQL injection on the login form -> privilege escalation
- password interception on the wire -> stealing user’s account information
- password brute forcing -> stealing user’s account information
- unauthorised access to resources, i.e. user B can read or update user A’s information without their consent.
It’s also helpful to identify vulnerability points with these:
- login form (SQL injection, password brute forcing)
- the wire, i.e. the connection between the user and the server (password interception)
- whereever user information can be looked up
From here, we can identify mitigation steps fairly easily:
- Sanitize all user inputs.
- Secure the connection using SSL.
- Use bcrypt to store passwords.
- Force all sensitive information to be routed through authorisation middleware.
Generally, it’s good practise to keep these in separate documents; i.e. an attack tree (though often annotated with the vulnerability points), and a security plan. This allows you to consider the two separately when needed. The security plan should reference the attack tree in considering what attacks are being defended against. These are also living documents; as mentioned before, they will need to be reviewed and updated regularly.
Identifying Attack Vectors
A good place to check for attack vectors is to consider the generic attack points:
- Where does data enter the system? Unsanitised data can pose a risk, as can data that is not normalised to expected values.
- Where does data leave the system? Information leakage is a security issue where information that should not leave the system does, or is revealed by the system unintentionally (typically without effort on the part of the attacker).
- What sensitive data does the system use? Passwords an obvious answer that come to find first; also, consider email addresses and other personal details. Resources that should not be widely accessible to the public fall under this category as well; for example, if you are publishing a paid magazine online, you want to consider restricting access to it.
- Where and how is sensitive information stored? For example, when passwords aren’t being used, how are they being stored? Are you using bcrypt or are they being stored in plaintext?
This can be a difficult task. You have to be creative, and you will likely still not consider everything an attacker will. Having several people involved in developing the attack tree is very useful, as they will all have different mindsets and backgrounds to contribute. One technique I find useful is to visualise your program as a system, diagramming subsystems and information flow. Just as physical security engineers will study the physical layout of the area they are working to protect and bank robbers will often observe their target beforehand, it is another tool useful for visualising where security systems fit into the overall architecture.
Example
Let’s consider an example: I have a website that provides a front end for my small team’s ebook library. Here is the systems diagram I have for the site:
And here is a sample attack tree I’ve come up with:
What are the attack vectors? If we organise them by the four generic attack points, we could come up with:
- Where does data enter the system?
- login form
- user book uploads
- user metadata fields
- book cover images
- user bio
- Where does data leave the system?
- book download
- user bio display
- displaying catalog information
- book cover display
- What sensitive data is present in the system?
- passwords
- user catalog
- Where and how is sensitive information stored?
- passwords: stored in the database as bcrypted hashes
- user catalog: stored in the database and accessed through an access control list (ACL)


Govt planning to build Direct Provision centres in 13 counties
Plans are being drawn up for new Direct Provision centres with space for 5,500 asylum seekers.
The Government is promising to engage with local communities about the proposed accommodation.
So far this year, more than 3,700 people have applied for asylum in Ireland, the highest number in over a decade which has put pressure on the Government to find enough accommodation for them.
According to the Irish Times, the Department of Justice is looking for providers to operate the new Direct Provision centres.
They will be located in eight regions and cost at least €320m.
Kildare, Wicklow, Meath and Louth will be expected to house 1,200 people followed by 750 in Cavan, Donegal, Leitrim, Monaghan and Sligo.
There will be accommodation for 620 people in Dublin and 617 in Galway, Mayo and Roscommon.
The department is also promising to engage with locals following recent protests against plans for Direct Provision facilities.

Evo is a GUI application for PTCL Evo Wingle. Evo is a very lightweight (less than 100 KB) application which shows network status and statistics. Evo is designed from ground up to support multi-platform and have hooks for future improvements.
(Default Password: admin)
Open source world.
Evo code has been written in Python Programming Language, and its GUI is GTK based.
Therefore, to run Evo, Python Interpreter and PyGi are required.
Follow the below steps, to run Evo:
* Download the versions of Python Interpreter and PyGi for your OS.
* If you are having any problem in downloading, installing mail me at<EMAIL_ADDRESS>You can use the toolbar to navigate between different sections.
Red button on the toolbar indicate disconnected. While green, indicate connected. You can also use the red button to get to the main page, like in the above figure. On the main page you can check the network status like signal strength, network type etc.
You can use the info button to view info page. Where you can check the device info and network statistics, like in the below figure.
To change the setting of Evo application you can use this button. See the figure below.
In the connection tab of the above figure, Server is the URL to which Evo will make a request for checking connection. Moreover, Timeout (default: None – is the default timeout, which the underlying package set by itself) is the number of seconds Evo will wait for a response from the server. While Make Request (default: 10) is the number of seconds after which Evo will make another request from the server to check connection.
Copyright © 2014 Mahan Marwat. All rights reserved.
As we know that open-source, free-ware software relies on donation. So, if you want to donate mail at<EMAIL_ADDRESS>Send your feedback at<EMAIL_ADDRESS>* Will fix these issues in second version
If you have any project, whether it is Web-Based, CLI or GUI and wants to hire-me. Please let me know at<EMAIL_ADDRESS>I mainly program in Python. Below are the other technologies I know.
HTML5, CSS3, JavaScript (Jquery), Bootstrap (CSS framework), Django (Python framework), PyGi (Python framework) and a-lot more e.g (Regex, Django Template Language) and Python packages like (requests, BeautifulSoup, paths) etc.
PTCL Evo Wingle does not have its own GUI.
Yes, But then Evo will only indicate connection (Green button on toolbar)/disconnection (Red button on toolbar). Evo will not provide other info like statistics etc.
I am working on it. And very soon release self executable version without installing Python, PyGi.
Click on Evo application to select it. And press (Alt + F4). This works on window platform. Please check your OS manual for a keyboard shortcut to close an application.
