|
Set the prefix be used for the DSIG namespace. When the XSEC library creates XML Element nodes, it uses the prefix here for all nodes created. By default, the library assumes that the default namespace is used. The #createBlankSignature function will use this prefix to setup the dsig namespace. E.g. (assuming a call has been made to set the prefix to "ds") the <Signature> element will have a namespace attribute added of xmlns:ds="http://www.w3.org/2000/09/xmldsig#" If no prefix has been set, this attribute will be set as the default namespace
|
|
|
Set the prefix be used for the Exclusive Canonicalisation namespace. The Exclusive Canonicalisation specification defines a new namespace for the InclusiveNamespaces node. This function can be used to set the prefix that the library will use when creating nodes within this namespace. xmlns:ds="http://www.w3.org/2001/10/xml-exc-c14n#" If no prefix is set, the default namespace will be used
|
|
|
Set Id finding behaviour. The library de-references "#obj" URI references to ID attributes within a DOM document. Currently, the library first uses DOM calls to find if the Id has been properly set within the document via the parser or one of the DOM Level 3 calls to set an Id. If no Id is found of the correct name, the library then starts searching for attributes of a given name with the required value. This list defaults to "id" and "Id", but can be modified via a call to addIdAttributeName() The setIdByAttributeName call enables or disables the second part of the Id search. I.e. when the Id doesn't exist as an attribute of Type=ID, whether or not to search for an attribute of a name in the list of names. By default this behaviour is enabled.
|
|
|
Set the DOMDocument that the super class is operating within. Mainly used by the library itself.
|
|
|
Set Pretty Print flag. The pretty print flag controls whether the library will output CR/LF after the elements it adds to a document By default the library will do pretty printing (flag is true)
|
|
|
Register a URIResolver. Registers a URIResolver to be used by the Signature when dereferencing a URI in a Reference element |
|
|
Set prefix for XENC nodes. Set the namespace prefix the library will use when creating nodes in the XENC namespace |
|
|
Set prefix for XKMS nodes. Set the namespace prefix the library will use when creating nodes in the XKMS namespace |
|
|
Set the prefix be used for the XPath-Filter2 namespace. The XPathFilter definition uses its own namespace. This method can be used to set the prefix that the library will use when creating elements in this namespace xmlns:ds="http://www.w3.org/2002/06/xmldsig-filter2" If no prefix is set, the default namespace will be used

Problem 56 : Powerful Digit Sum
Introduction
Let’s start with a link to the problem: Euler Project Problem 56.
The problem had been solved many times using a bruteforce approach, or an analytical approach that uses some estimation to zoom on the range of values to search for the max.
I present here a kotlin
implementation with an optimization approach that minimizes the search space considerably and allows to find the solution for theoritically any arbitrary base and exponent values.
Bruteforce Solution
I have seen this done multiple times on the internet. An often cited solution in python looks like this:
print max(sum(map(int, str(a**b))) for a in xrange(100) for b in xrange(100))
I have to say, the terseness of this solution is impressive. Python is just impressive. I wish it was typed :)
Having said that, I feel this solution (and other uglier ones in uglier languages) that uses the pure bruteforce approaches are, mmm, missing the point? somehow we need to be smarter, no?
Before, desperately, trying to produce some better solution, I am going to offer a kotlin solution that is bruteforce. Here it is:
fun sumDigitsOfExponent(base: Int, exp: Int): Int =
BigInteger(base.toString())
.pow(exp)
.toString()
.toCharArray()
.map { it - '0' }
.sum()
fun maxPowerDigitSumBruteforce(maxBase: Int, maxExp: Int): Int =
generateSequence(1) { it + 1 }
.take(maxBase)
.flatMap { a ->
generateSequence(1) { it + 1 }
.take(maxExp)
.map { b ->
sumDigitsOfExponent(a, b)
}
}
.max() ?: 0
On my laptop, this takes between a 50 to 200ms. The median is around 78ms to find the solution. No doubt it is fairly fast! But it is also no doubt exhaustive. We do not use any knowledge of how numbers work, how numbers relate. No heuristics at all either.
Optimized Solution Using Max Digit Sum
In order to eliminate a large area of the search space, we can use some of our knowledge about the problem without compromising its generality.
First, we know that the max is likely to be closer to the top, rather than the bottom. So we start from larger values of both a
and b
(base and exponent), moving downward. That way we’ll hit the max sooner than later.
Second, if we keep the max we found so far as we scan values, we can also stop whenever the max sum possible is lower than the so-far-found max. Basically, once we can never produce a larger number from the one we have identified as our running max, then we stop.
How do we calculate the max possible digit sum from a number x
? well, let’s use the equation for the number of digits in a number and multiply it by 9:
MaxDigitSum(X) = floor(1 + log10(X)) * 9
If we use this approach, we cut the number of culculated digits sums from 99*99 = 9801
in the case of the bruteforce to around 2984
. This is only 30%
of the total search space. Not bad.
Here is the code for this approach implemented in kotlin:
fun maxPowerDigitSumOptimized(maxBase: Int, maxExp: Int): Int {
var base = maxBase
var maxSum = -1
while (maxSum < maxDigitSum(base, maxExp)) { // base loop
var exp = maxExp
while (maxSum < maxDigitSum(base, exp)) { // exp loop
maxSum = maxOf(maxSum, sumDigitsOfExponent(base, exp))
exp -= 1
}
base -= 1
}
return maxSum
}
fun digitCountOf(base: Int, exp: Int): Int = Math.floor(1 + exp * Math.log10(base.toDouble())).toInt()
fun maxDigitSum(base: Int, exp: Int): Int = 9 * digitCountOf(base, exp)
This solution took, on my laptop, between 24ms and 40ms. The median is about 25ms. This is 50%
improvement. Not bad.
Conclusion
I believe there are other optimizations that we can do. For example, all bases that
have zeros are unlikely to produce maximums. For example 10
, 100
, 30
, etc. However, this requires us to do more checks to establish, so might cause more overhead than its worth (unless we find an easy way to avoid doing the 10
multipliers).

Type a unique phrase that no-one else would choose
Please make sure it is something no-one else would choose
Such as a few random words that you can remember
This ensures that your location doesn't end up with the same anonymous ID as somewhere else
For example: "fierce tree folks butter" (it doesn't have to include your place name)
Tip: use the idea described at https://preshing.com/20110811/xkcd-password-generator/.
Your location's anonymous ID is: Your location's generated URL is:(send this to people who physically spend time at your location with if QR code scanning is not working)
How this works:
Your phrase is 'hashed' to form a unique id.
This is done in your browser, your phrase in plain text never leaves your phone or computer.
Assuming you used a phrase which included what would be a strong unique password, it is virtually impossible to go from the hash alone back to your
phrase.
However, people still may be able to reidentify your location, especially those who know
handshake with your location.
This is Open Source and so you can check

Trump honours ISIS-fighting dog Conan at White House
A special hero of the recent take down of the ISI leader al-Baghdadi received an audience with the White House to thank him for his good work.
“It was a flawless attack, al-Baghdadi’s gone, and we gave Conan a medal and a plaque. He’s a very, very special dog,” the president said at the White House about the Belgian Malinois.
“He’s an incredible dog. We’re very honoured to have Conan here and to give Conan an award,” he said in the Rose Garden ceremony after meeting with Special Forces troops in the White House.
“He was badly hurt but he recovered very quickly. Conan is a tough cookie, nobody’s going to mess with Conan,” the president continued, alluding to the dog’s injuries when the ISIS cutthroat blew himself up with a suicide vest.
The commander-in-chief then extolled the canine’s fighting abilities.
“This is the ultimate fighter, ultimate everything. Ultimate in terms of sniffing drugs,” Trump said.
Mr Trump said he asked Conan’s handlers “what chance a person [would] have against Conan without the guns, I guess the answer was pretty much none. No chance, it was amazing.”
“We had a case [on the southern border] where we had drugs in a cylinder in a car. It was undetectable. The dog came in and jumped on the hood, pointing — wow! — incredible sense of smell,” said the president, who was accompanied by Vice President Mike Pence and first lady Melania Trump.
As the president and his wife walked back into the White House, a reporter asked the first lady if she wanted to adopt Conan for the couple’s son, 13-year-old Barron.
The president and his wife chuckled at the question.
The first family does not own a dog.
Service dogs have been used by the military for decades.
On the battlefields of Iraq and Afghanistan, the animals’ most critical function has been sniffing out hidden roadside bombs or IEDs — and they have saved untold numbers of American lives.

DeFi Reading List
This is a living, breathing page, and represents the latest and most relevant academic research pertaining to DeFi and arbitrage opportunities arising from it.
-
Flash Boys 2.0: Frontrunning, Transaction Reordering, and Consensus Instability in Decentralized Exchanges [arXiv Pre-Print]
Easily the most prominent paper on this list. Describes the operation of various DEXes and categorises them accordingly, details various arbitrage techniques, presents a formal, mathematical model of what the authors call Priority Gas Auctions (PGAs), and provides empirical data derived from the authors' novel instrumentation infrastructure (which is also thoroughly described).
-
Attacking the DeFi Ecosystem with Flash Loans for Fun and Profit [arXiv Pre-Print]
Describes how flash loans can be used to create and subsequently exploit arbitrage opportunities and also perform wash trading, presents a case study of two real-world instances of such activities, and also formulates an optimisation model to maximise profit from such attacks. Paper is very recent (as of the time of writing, at least).
-
Flash Boys 2.0 - Ari Juels - CES Summit '19 [YouTube Video]
A presentation given by Ari Juels - one of the authors of #1 - on the corresponding paper (i.e. #1). Provides a good overview of the paper in a seminar presentation format.
-
SoK: Transparent Dishonesty: front-running attacks on Blockchain [arXiv Pre-Print]
Surveys instances of frontrunning across the top 25 most popular DApps (at the time of publication, obviously) and provides a detail analysis of the Status.im ICO. The latter analysis uncovers evidence indicative of miner frontrunning of token purchases (somewhat analagous to pre-mining of days of old).
-
On the Instability of Bitcoin Without the Block Reward
Analyses the security of the Bitcoin consensus model without block rewards and finds that this results in an undesirable equilibrium state where miners collude to steal rewards by forking attractive blocks. While this paper addresses Bitcoin - the results of which have some troubling implications for its long-term future - the results provide an interesting perspective on Miner Extractable Value (MEV), a concept explored in #1. It may be of interest to note that this paper is somewhat old by cryptoeconomics standards.
-
The Cost of Decentralization in 0x and EtherDelta
An interesting blog post discussing the unique challenges that decentralisation of exchanges presents - with particular emphasis on both 0x and EtherDelta (both of which receive specific discussion in #1).
-
Attacking the DeFi Ecosystem with Flash Loans for Fun and Profit
A blog post covering its associated paper (#2). Provides a nice outline and summary of the work.
-
Market Manipulation as a Security Problem [arXiv Pre-Print]
Presents various desirable security properties of traditional financial exchanges and details how various market manipulation strategies can undermine them. While this paper is in no way specific to cryptocurrencies, it caught my attention as I'm of the personal belief that both its content and research methodologies can be applied to the current DeFi ecosystem.
-
The Decentralized Financial Crisis: Attackng DeFi [arXiv Pre-Print]
Describes what the authors deem to be systemic weaknesses in current DeFi markets and how they may be analagous to the Global Financial Crisis (GFC) of 2008. Very promising paper (at least a priori) due to its fascinating premise and also how fresh it is (once again, as of the time of writing).
-
How to turn $20M into $340M in 15 seconds
Blog post detailing some very severe perceived weaknesses in the MakerDAO (v2) protocol and corresponding governance model. This article received a fair amount of news coverage in popular cryptocurrency-related media and is only a few months old.

THE MAN IN THE IRON MASK
A Film Review by James Berardinelli
RATING: **1/2 OUT OF ****
United States, 1998 U.S. Release Date: 3/13/98 (wide) Running Length: 2:10 MPAA Classification: PG-13 (Mild and infrequent profanity, non-explicit sexual situations, non-graphic violence) Theatrical Aspect Ratio: 1.85:1
Cast: Leonardo DiCaprio, Jeremy Irons, John Malkovich, Gerard Depardieu, Gabriel Byrne, Anne Parillaud, Judith Godreche, Peter Sarsgaard, Hugh Laurie Director: Randall Wallace Producers: Randall Wallace and Russ Smith Screenplay: Randall Wallace based on the novel by Alexandre Dumas Cinematography: Peter Suschitzky Music: Nick Glennie-Smith U.S. Distributor: United Artists
During the heyday of his career as a writer, Alexandre Dumas penned three novels about a quartet of the best-known characters in European literature: Athos, Porthos, Aramis, and D'Artagnan. In 1844, Dumas published THE THREE MUSKETEERS. The next year, he followed this with TWENTY YEARS LATER. Finally, between 1848 and 1850, his serialized THE MAN IN THE IRON MASK came to print. Like all the best historical fiction, this trilogy uses real characters and real events, but imagines and re-invents relationships and circumstances. The resulting narratives are complex and entertaining, featuring ample quantities of swashbuckling adventure while focusing on well-rounded characters and murky politics.
While THE THREE MUSKETEERS has been adapted more than a dozen times for film and television, this new version of THE MAN IN THE IRON MASK is only the sixth (the last was 1979's THE FIFTH MUSKETEER). The writer/director is Randall Wallace, who scripted BRAVEHEART for Mel Gibson. The problem with this movie is that Wallace has attempted to squeeze a 500-page book into a 130-minute motion picture, something that can't be done without major sacrifices. The resulting product is high on melodrama and low on the character depth and political machinations that are the novel's strengths. THE MAN IN THE IRON MASK is also surprisingly devoid of gripping adventure. Hardly a gun is fired or a sword drawn until the climactic half-hour.
Although the basic plot follows that of the novel, the central characters, older versions of the Four Musketeers, have been simplified into generic heroes. Their motives, as presented in the movie, are superficial. Athos (John Malkovich) has invested all of his hope and faith in his son, Raul (Peter Sarsgaard). Porthos (Gerard Depardieu) is enjoying a life of debauched revelry. Aramis (Jeremy Irons) has become the military leader of the Jesuits. And D'Artagnan (Gabriel Byrne) remains the devoted captain of the Musketeers. The story, which transpires in 1662 France, blossoms from a rift that grows between the older three men and their former protégé. D'Artagnan's unquestioning loyalty to the cold, self-serving king, Louis XIV (Leonardo DiCaprio), places him at odds with Porthos, Athos, and Aramis after the king sends Athos' son to the front lines of a battle so that he can woo Raul's fiancee, Christine (Judith Godreche). And there is yet another player, the mysterious Man in the Iron Mask, who languishes in prison, his face hidden from his captors because of his eerie resemblance to King Louis.
Dramatically, the film is weak, and plays more like a soap opera than a screen adaptation of a classic novel. The costumes and set design are impressive, but they're all just window dressing. The plot has the hit-and-miss feel that one might expect from any attempt to cram so much material into such a limited running time. The political background, which includes riots by the starving common people, border wars, and religious power plays, is given short shrift – a line or two here, a quick scene there. The characters aren't all that interesting, since much of their complexity has been stripped away to make them more familiar and appealing to today's movie-going crowd. (For example, the Aramis of the book comes close to being a villain, but the Aramis of the movie is unquestionably heroic.) The unfortunate result is that the first 90 minutes, which are primarily intended to be dramatic, come across as rather dull. Only in the final half-hour, when we are treated to several displays of derring-do, does THE MAN IN THE IRON MASK come alive.
In the wake of his popularity explosion resulting from TITANIC, Leonardo DiCaprio will prove to be THE MAN IN THE IRON MASK's chief drawing card. He plays two roles (Louis and the masked man), but fails to do either especially well. The somewhat stilted and occasionally- ripe dialogue doesn't roll easily off his tongue and, for the most part, he gives the impression that he's playing dress-up. Those who found DiCaprio inadequate in ROMEO + JULIET will likely cringe at his work here. Equally ineffective are the two female leads. Judith Godreche, who was strong in RIDICULE, is reduced to a lifeless mannequin as Louis' mistress, Christine. And Anne Parillaud, who hasn't been impressive since LA FEMME NIKITA, offers a flat interpretation of Queen Anne, Louis' widowed mother.
Fortunately, the veteran actors playing the Musketeers are far better, and they have the lion's share of the screen time. Malkovich is as delicious as ever, and it's refreshing to see him in a role where the primary characteristic is nobility rather than psychotic behavior. As D'Artagnan, Gabriel Byrne successfully essays a character who is increasingly conflicted and uncertain about where his true loyalty lies. Gerard Depardieu is delightful as the somewhat-fatuous Porthos. And, as Aramis, Jeremy Irons gives his most lively performance in a long time.
Ultimately, the negatives in THE MAN IN THE IRON MASK nearly counterbalance the positives. While the last half-hour is exhilarating and recalls the best swashbuckling movies, the film takes a little too long to get there, and, along the way, is only moderately successful as an historical drama or an adventure. DiCaprio's name will undoubtedly give this picture a box-office boost, but his two characters aren't the movie's focus – the aging Musketeers are. And those who are interested in learning how their stories end will find greater satisfaction in reading Dumas' novel than in sitting through this thin adaptation.

Use this directive to auto-bootstrap an application. Only one ngApp directive can be used per HTML document. The directive designates the root of the application and is typically placed at the root of the page.
The first ngApp found in the document will be auto-bootstrapped. To use multiple applications in an
HTML document you must manually bootstrap them using angular.bootstrap
.
Applications cannot be nested.
In the example below if the ngApp
directive would not be placed
on the html
element then the document would not be compiled
and the {{ 1+2 }}

About us
The purpose of our project is to assist high school students learn about Australia’s involvement in WWI, and what day-to-day life was like in Australia during the war. Based on our group's research and our collective experiences of static and unengaging online learning during lockdowns over the past 18 months, we wanted to create a learning supplement that is engaging, novel, and entices users to explore and interact with information. During our research into WWI, we found that a lot of resources focus on the battles, conflict, and casualties of the war, however, after exploring our chosen datasets, we found that they were rich in information that showed what life was like in Australia during the war. This information included newspaper articles, images, and captions that portrayed carnivals in West End, dress-up days at hospitals, school-life, butterfly collectors, and girls cricket teams at local schools.
While the state library of Queensland datasets do provide an interesting look into day-to-day life during WWI, there are gaps in the information that they provide and it is important to acknowledge that. As the dataset is based on excerpts from newspapers, the content is subject to any prejudice that the editors and writers may have had. Additionally, based on our review of the datasets, there is no mention of First Nations people in the dataset or their experiences in the war. Therefore, while we do state that we want to teach our users about day-to-day life in Australia and Australian experiences in WWI, our datasets do leave out First Nations people and in future iterations or versions of this concept we would ideally include their views, stories and experiences as well.

--- title: "Increases in crime-related demand are hitting some forces harder than others" author: Matt Ashby date: '2021-07-19' categories: - Crime and justice chart of the week tags: - crime - crime pressure - crime severity - police ---
One way to understand crime-related demands on police forces is to track ‘crime pressure’, a measure of investigative workload representing the number of crimes reported to a force per officer, weighted according to Office for National Statistics estimates of the relative severity of different crimes. Over the past decade years, this measure has risen in every police force in England and Wales, and has doubled in many places.

The Office for National Statistics (ONS) publishes estimates of the severity of different types of police-recorded crime, derived from the average sentence imposed in court for each type of offence. In the same dataset, ONS publishes an overall estimate of the severity of crime per capita in each police force area. To convert this to an estimate of crime severity per officer (referred to above as crime pressure), severity per capita was multiplied by police force area population1 and then divided by the number of full-time equivalent police officers in each force. Crime pressure is therefore defined as the severity of police-recorded crime per full-time equivalent officer.
Estimates of the severity of different crimes are inherently limited, although they are likely to be more informative for some purposes than simply counting crimes (which implicitly assumes all crimes are of equal importance). For a further discussion of this, see Comparing methods for measuring crime harm/severity.
Police force area populations were calculated by aggregating mid-year population estimates for local authorities to police force areas using the ONS open geography portal local authority to police force lookup table.↩


I’ve finished renaming pyinstall to its new name: pip. The name pip is a acronym and declaration: pip installs packages.
I’ve also added a small feature intended for Google App Engine users, allowing you to zip and unzip packages in an environment. For instance:
$ pip zip --list
In ./lib/python2.5/site-packages:
No zipped packages.
Unzipped packages:
paste (98 files)
pygments (64 files)
tempita (7 files)
weberror (31 files)
webob (22 files)
webtest (9 files)
nose (43 files)
setuptools-0.6c9-py2.5.egg (43 files)
simplejson (28 files)
$ pip zip webob
Zip webob (in ./lib/python2.5/site-packages/webob)
Right now this doesn’t work well with egg directories (i.e., packages installed with easy_install), though that shouldn’t be too hard to resolve. pip install itself does not install packages into egg directories (it does install eggs, which is to say it installs all the egg metadata and works fine with pkg_resources).
I don’t really use buildout myself, but I would like to throw it out there that I think someone should create a pip recipe as an alternative to zc.recipe.egg. There’s not really a stable programmatic API in pip at this point, but with no consumers of the API it feels like premature design to settle on something now — integrate with pip and we can figure out what that stable API should be. If you integrate buildout, probably another useful feature would be an option have to pip freeze write the packages out to a setting in your buildout.cfg.

I just noticed that
easy_install pip
doesn’t add pip.exe to Scripts folder on Windows. Addingentry_points = {'console_scripts': ['pip=pip:main']}
to setup.py fixes that. I think it’s a good idea to do that even if you don’t want to depend on setuptools.You know what’s funny? [This is funny](http://search.cpan.org/dist/pip/).
OK, new name: pippiintpip (“pippiintpip installs Python packages, it is not the Perl Installation Program”)
That’s weird… I looked around for something called “pip” and only came upon a command-line utility for redirecting pipes to things like editors. Gentoo had it packaged, but not Ubuntu. But I didn’t see the Perl thing at all.
Yeah, pip is a great Perl installer.
How about pypi? Python Package Installer …
pypi is just too much like pypy. At some point in time, you’re going to have to explain to a new user that you meant “pypi”, not “pypy” – and they’re just going to raise their eyebrow at you.
How about “pyp” – for “python pip”? Or maybe not… :)
This ain’t “whoa there we were first!!” kind of thing, btw, I was just terribly amused that people in two different “P-language” communities had the exact same naming idea.
@Aristotle
Maybe both projects should merge into yet another pip: one that installs for any language running on the Parrot VM :)
Isn’t really a name space issue? Look, we could name one:
Perl\pip
And the other
Python\pip
Wouldn’t it really be:
Perl::pip
And the other
python.pip
pip actually looks like it has some similarities.
.p5i
files are the same as pip requirement files, and.p5z
are like pybundles. Are there conventions for declaring dependencies in Perl? The Perl pip has a terrible search score — if you just search for “pip” it hardly shows up at all.The “META.yml” spec describes a standard for declaring dependencies of Perl modules. See here:
http://module-build.sourceforge.net/META-spec.html
This file is automatically generated when you “make dist” a CPAN module, so it is usually available. You can see an example for the “pip” distribution itself:
http://search.cpan.org/~adamk/pip-0.13/ http://search.cpan.org/src/ADAMK/pip-0.13/META.yml

Good luck with this!
I particularly like the aspects highlighted at http://www.diigo.com/annotated/079484ba977b115c009b8faeb710e92e
trying to figure how integrate it with a web server (and especially virtualenv). Any idee? Should I only have to set path and VIRTUAL_ENV environnemnt variable ?
If you are using mod_wsgi, look at: http://code.google.com/p/modwsgi/wiki/VirtualEnvironments — it should all be applicable here. If you are using HTTP proxying from a web server, it’ll all be automatic so long as you start the server from within the environment.
thanks for the link. Exactly what I was looking for.
two things:
1- about the name pypy (python interperter build on python) and pypi (python package index aka:cheeseshop) are already a mess, may as well leave it as pip since that is perl.
2- could you explain this thing about egg? I personally like not-zipped eggs as they let me read the source of libraries failing and/or poor documentation, it’s great for development.
How about “pint”?
“For inexperienced user this package requires a pint of Python to be installed” (sounds like minced “Python” cocktail – not too brilliant for an ad, brobably, but illustrates what can happen to your site-libs over the time if you WON’T USE it)
It also could be thought as an abbreviation of “Python INsTaller” without “s”, because it doesn’t install for Python for System, but rather system for Python. Missing “s” can be the Sign that pythonS are Silent Snakes that do not hiSS on inStall.
I’ve just started a buildout recipe for pip: http://www.bitbucket.org/gawel/gprecipepip/overview/
Looks promissing. The recipe run a pip install command with subprocess.call() (cant use main() directly because you use sys.exit()) then run zc.recipe.egg.Scripts with all eggs found in parts/name/lib/pythonXX/site-packages and src/. Works like a charm :)

Hello!
Does anyone have an experience using EmonPi/EmonTX/EmonTH for monitoring/evaluating a Passivhaus? I am helping someone put together a setup and would be interested in any comments.
The setup is complicated by having multiple location where wires are accessible and the (obvious) inability to puncture walls. The aim is to quantifiably say how the house performance stacks up. The House has PV arrays (x2), immersion heaters (x3), and small separate boost heaters (x3).
Currently the setup is just an EmonPi and three EmonTH. This allows capture of whole house consumption and production, with external and internal temperature and humidity monitoring. The plan is to extend the setup to allow a more detailed breakdown of energy in the house ( with 2x EmonTX) now. I am also thinking about which sensors (e.g. CO2) would give extra insight. I would interested in hearing what approaches other people have taken to passive house and if any particular measurements have been more useful than others?
Thanks in advance,
Tomas
Re: Passivhaus (Passive house) monitoring with EmonPi/EmonTX/EmonTH ...
Hello Thomas, John Cantor and I put together a system for a passivhaus application that involved:
I would recommend ensuring that you have good start and end manual meter readings from the electricity meter and any heat metering if needed over the measurement period in order to double check the accumulated kwh elec and heat recorded in emoncms.
If you extend the system with heat metering, kamstrup heat meters have the option of either a mbus or pulse output card, Id go for the mbus and either build the mbus reader Im using for the heat pump monitor or use the heat pump monitor once its ready (which could also serve as your central hub): http://openenergymonitor.org/emon/node/11826
The coheating module by Eric AMANN might be useful too: http://openenergymonitor.org/emon/node/6258
Re: Passivhaus (Passive house) monitoring with EmonPi/EmonTX/EmonTH ...
Hi Trystan,
Thanks for the help. Tomas has been helping us to design and install a monitoring system for our house. Our house has been certified as Passivhaus Plus but we want to monitor its actual performance. We have a 9.5kWpeak solar PV system with two inverters. So we want to monitor the output from the inverters (two CT clips) and our import or export to the grid (one CT clip).
We do not have any wet heating system and are all electric for our heating and hot water - so I am not sure if we need heat meters. I was planning just to measure the electricity used for hot water and heating. We have:
1. A 1kW postheater in the ventilation system - we can put a CT clip on the live wire to the heater to measure power used
2. Four towel warmers and one electric radiator on a single circuit so we can put a CT clip on this circuit to measure power use.
3. Two 3kW immersion heaters attached to Immersun diverters so we can divert electricity we would otherwise export into our hot water tank.
4. One 3kW immersion heater at the top of the hot water that runs off the normal electricity to boost hot water on cloudy days.
The heating circuits and inverters are in the Store room on the SF so we would need a EmonTX there with 4 clips. The hot water is in the GF Utility Room so we would need the EmonPi with two CT clips there. The electricity meter is in an external cabinet so I was planning to have an EmonTX with two clips there (one for the import/export from the grid and the second for our car charger) this could have an external temperature sensor hung on the north side of the meter cabinet.
Does this sound reasonable? I guess we could add a hot water meter to measure the hot water we actually use rather than the power going into the tank.
Thanks for the help.

Before beginning work, the following are required:
The project must be renamed in package.json
.
Change the line that reads "name": "DesignInTheBrowserBootstrap",
to specify your new project's name e.g "name": "Client XYZ",
.
A fresh git repository must be created:
In the same folder as the file package.json
, run:rm -rf .git && git init && git add . && git commit -m "First commit"
This new repository will need to be uploaded somewhere eventually e.g Github, but this can be left till later.
Create a staging-ssh-config.js
file by renaming staging-ssh-config.example.js
. See the README.md
"Deploying to a staging server"->"Setup per project" for information on how to configure it.
