10.9 Cache Array Routing ProtocolCARP is an algorithm that partitions URI-space among a group of caching proxies. In other words, each URI is assigned to one of the caches. CARP maximizes hit ratios and minimizes duplication of objects among the group of caches. The protocol consists of two major components: a Routing Function and a Proxy Array Membership Table. Unlike ICP, HTCP, and Cache Digests, CARP can't predict whether a particular request will be a cache hit. Thus, you can't use CARP with siblings—only parents. The basic idea behind CARP is that you have a group, or array, of parent caches to handle all the load from users or child caches. A cache array is one way to handle ever-increasing loads. You can add more array members whenever you need more capacity. CARP is a deterministic algorithm. That is, the same request always goes to the same array member (as long as the array size doesn't change). Unlike ICP and HTCP, CARP doesn't use query messages. Another interesting thing about CARP is that you have the choice to deploy it in a number of different places. For example, one approach is to make all user-agents execute the CARP algorithm. You could probably accomplish this with a Proxy Auto-Configuration (PAC) function, written in JavaScript (see Appendix F). However, you're likely to have certain web agents on your network that don't implement or support PAC files. Another option is to use a two-level cache hierarchy. The lower level (child caches) accept requests from all user-agents, and they execute the CARP algorithm to select the parent cache for each request. However, unless your network is very large, many caches can be more of a burden than a benefit. Finally, you can also implement CARP within the array itself. That is, user-agents connect to a random member of the cache array, but each member forwards cache misses to another member of the array based on the CARP algorithm. CARP was designed to be better than a simple hashing algorithm, which typically works by applying a hash function, such as MD5, to URIs. The algorithm then calculates the modulus for the number of array members. It might be as simple as this pseudocode: N = MD5(URI) % num_caches; next_hop = Caches[N]; This technique uniformly spreads the URIs among all the caches. It also provides a consistent mapping (maximizing cache hits), as long as the number of caches remains constant. When caches are added or removed, however, this algorithm changes the mapping for most of the URIs. CARP's Routing Function improves on this technique in two ways. First, it allows for unequal sharing of the load. For example, you can configure one parent to receive twice as many requests as another. Second, adding or removing array members minimizes the fraction of URIs that get reassigned. The downside to CARP is that it is relatively CPU-intensive. For each request, Squid calculates a "score" for each parent. The request is sent to the parent cache with the highest score. The complexity of the algorithm is proportional to the number of parents. In other words, CPU load increases in proportion to the number of CARP parents. However, the calculations in CARP have been designed to be faster than, say, MD5, and other cryptographic hash functions. In addition to the load-sharing algorithm, CARP also has a protocol component. The Membership Table has a well-defined structure and syntax so that all clients of a single array can have the same configuration. If some clients are configured differently, CARP becomes less useful because not all clients send the same request to the same parent. Note that Squid doesn't currently implement the Membership Table feature. Squid's CARP implementation is lacking in another way. The protocol says that if a request can't be forwarded to the highest-scoring parent cache, it should be sent to the second-highest-scoring member. If that also fails, the application should give up. Squid currently uses only the highest-scoring parent cache. CARP was originally documented as an Internet Draft in 1998, which is now expired. It was developed by Vinod Valloppillil of Microsoft and Keith W. Ross of the University of Pennsylvania. With a little searching, you can still find the old document out there on the Internet. You may even be able to find some documentation on the Microsoft sites. You can also find more information on CARP in my O'Reilly book Web Caching. 10.9.1 Configuring Squid for CARPTo use CARP in Squid, you must first run the ./configure script with the —enable-carp option. Next, you must add carp-load-factor options to the cache_peer lines for parents that are members of the array. The following is an example. cache_peer neighbor1.host.name parent 3128 0 carp-load-factor=0.3 cache_peer neighbor2.host.name parent 3128 0 carp-load-factor=0.3 cache_peer neighbor3.host.name parent 3128 0 carp-load-factor=0.4 Note that all carp-load-factor values must add up to 1.0. Squid checks for this condition and complains if it finds a discrepancy. Additionally, the cache_peer lines must be listed in order of increasing load factor values. Only recent versions of Squid check that this condition is true. Remember that CARP is treated somewhat specially with regard to a neighbor's alive/dead state. Squid normally declares a neighbor dead (and ceases sending requests to it) after 10 failed connections. In the case of CARP, however, Squid skips a parent that has one or more failed connections. Once Squid is working with CARP, you can monitor it with the carp cache manager page. See Section <IP_ADDRESS> for more information. |

How to build Dockerfiles in Kubernetes
Table of Contents
1 Introduction
Besides running long running services, Kubernetes can be used to run batch jobs as well.
One can use this feature for example to build Dockerfiles. This short post wants to highlight a simple and elegant way of performing this task.
2 Pitfalls
Using Kubernetes jobs to build Dockerfiles seems to be a pretty straightforward task at the first sight. There are some pitfalls though.
2.1 Docker in Docker
We assume that your Kubernetes uses Docker as container runtime. That means that each of your host machine runs a Docker engine.
Jobs are realized as Pods running a single container. If you want to use
Docker commands (like docker build
, docker push
, etc.) from Jobs (i.e.
from inside a container) you are facing the problem of running Docker inside
Docker which is discouraged1 in general.
2.2 Docker Registries and Authentication
Even if you manage to execute Docker commands from inside the container, you
might be surprised when your first try to docker push
the built image.
That's because the push
command succeeds only when you are successfully
authorized by the Docker registry.
That's a minor issue only and Kubernetes is designed to mitigate such issues in a meaningful way.
2.3 Reusable Kubernetes jobs
Kubernetes resources (the more complex ones at least) are deployed via manifest files. The manifest file of a given deployment, pod, service, job etc. varies a bit from deployment to deployment that makes the manifest files hard to reuse.
For deployments, services, etc. resource types, we can use Helm that addresses exactly this issue. Unfortunately, Helm does not support jobs…
3 Building Dockerfiles in Kubernetes
The task we want to perform is to take a given git repository that contains a Dockerfile and potentially other helper files and build a Docker images in a Kubernetes cluster. Finally, we want to push the resulted Docker image to one or more Docker repositories.
So our inputs are:
- URL of a git repository
- tag(s) that will be assigned to the built image
- credentials that authorize us at the Docker registry
Let's first take care of the last in the list: Docker registry credentials.
3.1 Storing the Docker credentials in Kubernetes
Following the best practices, we will store our credentials as Kubernetes
secret
.
3.1.1 Option 1: Copy credentials from your laptop
This may be the simpler case. We assume that you have logged in to all the
needed Docker registries from your laptop and a proper config file has been
created at $HOME/.docker/config.json
.
We can copy the Docker credentials to the Kubernetes secret from this file:
kubectl create secret generic docker-image-builder-secret \ --from-file=.dockerconfigjson=${HOME}/.docker/config.json
secret "docker-image-builder-secret" created
3.1.2 Option 2: Specify credentials directly
Another option is to create the secret by specifying the credentials directly using the following command:
kubectl create secret docker-registry docker-image-builder-secret \ --docker-server=DOCKER_REGISTRY_SERVER \ --docker-username=DOCKER_USER \ --docker-password=DOCKER_PASSWORD \ --docker-email=DOCKER_EMAIL
secret "docker-image-builder-secret" created
3.2 Starting the job
The next task is to create a Kubernetes job which:
- starts a Pod that has
docker
CLI in it, see the official docker image - can use the host's Docker engine in order to perform the
docker build
command - has the docker credentials stored in the secret mounted at the expected
location (
$HOME/.docker/config.json
) - has a volume with the given git repository
When run, the pod shall execute a docker build
command with the right
parameters then a docker push
command for each of the image tag.
To write a complying job manifest takes some time but it is a reasonably simple task for an experienced Kubernetes user.
3.2.1 Starting a job in a reusable way
We will use the tool yemplate for starting the job. First, let's install
yemplate
.
go get -u https://github.com/origoss/yemplate
With yemplate
we can create job manifest templates similarly to Helm
charts.
An example job manifest template can be found here. We will use it to build and push a Docker image with the following parameters:
- git repository
- where the Dockerfile is stored is at https://github.com/origoss/dockergit.git.
- tags
- of the resulting image are:
- docker.origoss.local/dockergit:latest
- origoss/dockergit:18.04.0-ce
- origoss/dockergit:latest
First, we check the job manifest that is created by yemplate
.
yemplate https://raw.githubusercontent.com/origoss/k8s-docker-build/master/docker-build.yaml.t \ --set "gitrepo=https://github.com/origoss/dockergit.git" \ --set "tags[0]=docker.origoss.local/dockergit:latest" \ --set "tags[1]=origoss/dockergit:18.04.0-ce" \ --set "tags[2]=origoss/dockergit:latest"
apiVersion: batch/v1 kind: Job metadata: name: docker-image-builder spec: template: spec: containers: - name: builder image: docker workingDir: /git volumeMounts: - name: dockersock mountPath: /var/run/docker.sock - name: dockerconfig mountPath: /root/.docker - name: gitrepo mountPath: /git command: - sh - -c - | set -e TAGS="-t docker.origoss.local/dockergit:latest -t origoss/dockergit:18.04.0-ce -t origoss/dockergit:latest " cd $(ls -tc -1 | head -n1) echo "docker build $TAGS ." docker build $TAGS . echo "docker push docker.origoss.local/dockergit:latest" docker push docker.origoss.local/dockergit:latest echo "docker push origoss/dockergit:18.04.0-ce" docker push origoss/dockergit:18.04.0-ce echo "docker push origoss/dockergit:latest" docker push origoss/dockergit:latest restartPolicy: Never volumes: - name: dockersock hostPath: path: /var/run/docker.sock type: Socket - name: dockerconfig secret: secretName: docker-image-builder-secret items: - key: .dockerconfigjson path: config.json - name: gitrepo gitRepo: repository: https://github.com/origoss/dockergit.git
We can use this template to run the job and build and push our Dockerfile in Kubernetes.
yemplate https://raw.githubusercontent.com/origoss/k8s-docker-build/master/docker-build.yaml.t \ --set "gitrepo=https://github.com/origoss/dockergit.git" \ --set "tags[0]=docker.origoss.local/dockergit:latest" \ --set "tags[1]=origoss/dockergit:18.04.0-ce" \ --set "tags[2]=origoss/dockergit:latest" | \ kubectl apply -f -
job.batch "docker-image-builder" created
If you are concerned with the many --set
parameters you can create a yaml
file with the parameter settings.
gitrepo: https://github.com/origoss/dockergit.git tags: - docker.origoss.local/dockergit:latest - origoss/dockergit:18.04.0-ce - origoss/dockergit:latest
We can run the job that reads the parameters from the params.yaml
file.
yemplate https://raw.githubusercontent.com/origoss/k8s-docker-build/master/docker-build.yaml.t \ -f params.yaml | \ kubectl apply -f -
job.batch "docker-image-builder" created

GATTACA (Columbia - 1997) Starring Ethan Hawke, Uma Thurman, Jude Law, Gore Vidal, Alan Arkin, Loren Dean Screenplay by Andrew Nicol Produced by Danny DeVito, Michael Shamberg, Stacey Sher Directed by Andrew Nicol Running time: 112 minutes
***1/2 (out of four stars) Alternate Rating: A-
Note: Some may consider portions of the following text to be spoilers. Be forewarned.
-------------------------------------------------------------
Nobody in Hollywood could have been more pleased with the scientific breakthrough announced earlier this year that British researchers had performed the first successful cloning of a live sheep than those at Sony Pictures associated with the GATTACA project. In terms of timing, such news couldn't have been more perfectly orchestrated, bringing to the forefront of public awareness the increasing sophistication in the science of genetic research over the past decade. When one combines this with the rampant paranoia and mistrust of the government pervasive in popular culture -- the number of conspiracy-oriented books lining shelves in stores and the success of similarly-themed TV show THE X-FILES is indication enough -- it's the perfect climate for the release of a film like GATTACA, which profiles a dystopic world of the future where one's DNA is the most crucial and valuable commodity.
Yet, like most great science-fiction, the strength of GATTACA is that the film really isn't exclusively a science-fiction film -- at its core, it's a very human and often poignant story which deals with the themes of potential, spirit and identity. There's no heavy reliance on showy visual effects or displays of stunning future technology, as is typical in most sci-fi films; GATTACA is essentially a character-oriented drama spun off from a dynamite premise.
It's the not-too-distance future, and scientific advancements have reached an advanced state where genetic tinkering allows the rich to create offspring literally devoid of any imperfection. Society has been divided into two distinct classes, where success is determined by science: the genetically-engineered 'Valids', and the naturally-conceived 'In-Valids' who are limited by society due to their imperfect DNA structures to serve as working drones. It's a world where prosperity is predetermined at birth; the Valids have the world at their feet -- an infinite realm of possibilities to pursue -- while the In-Valids have nary a reason to hope. So what's Vincent Freeman (Ethan Hawke), an In-Valid with nearsightedness, emotional volatility and a congenital heart condition, to do? Burdened his whole life by living in the shadow of his Valid brother Anton (Loren Dean), and by his seemingly-unfulfillable ambition to become an aeronautics navigator for the elite Gattaca Aerospace Corporation, he's left toiling as a maintenance worker, eyes aimed upwards at the stars.
Of course, Vincent is not content to passively accept his fate, and GATTACA, then, is essentially an Underdog Film -- a familiar One Man Against Society story. On that level it works well, but where the film truly flourishes is when it focuses upon Vincent's indomitable determination to surpass expectations and push himself to the boundaries of physical limitation in order to attain his dream, against all forms of adversity.  Aided immeasurably by Michael Nyman's stirring score -- to date, the best score I've heard this year -- it's a genuinely moving celebration of the human spirit, while avoiding the trappings of becoming schmaltzy or sentimental.
In fact, New Zealander screenwriter-director Andrew Nicol's feature debut is such an auspicious piece of work that it's mildly disheartening that the film delves into a generic thriller subplot, dealing with a murder mystery on the grounds of the Gattaca Aerospace Corporation. While this successfully taps into paranoiac elements -- given that Vincent's true identity can be traced through any form of DNA residue left, it's entrancing to observe his ritualistic grooming each morning to attempt to mask his true identity, and fascinating to watch him attempt to cover his tracks by stealthily vacuuming his desk and leaving decoy DNA samples (it reminded me in a sense to the great moment in WAIT UNTIL DARK where Alan Arkin's Harry Roat Jr. markedly pointed out that he hadn't *touched* anything in Susie's apartment) -- it also leaves gaping holes in logic which push credibility beyond the bounds of belief; consider, if you will, wily Detective Hugo (the aforementioned Mr. Arkin) unable to match a completely undisguised Vincent against a clearly-identical headshot image -- perhaps *Hugo* is nearsighted too. The murder mystery flounders, adding very little to enhance GATTACA and distracts from the film's primary theme, but it doesn't sink it.
Another vaguely ineffective subplot in GATTACA involves fellow Gattaca Aerospace Corporation trainee Irene, a genetically perfect woman (Uma Thurman - 'nuff said) who provides an interesting counterpoint to Vincent in terms of their approaches to adversity, but generally serves merely a decorative role in the film.
Among its arsenal of strengths (crisp, sharp visuals by cinematographer Slawomir Idziak; wonderful costumes by the legendary Colleen Atwood), GATTACA benefits from superb casting. Mr. Hawke is very solid and sympathetic as the undaunted protagonist and demonstrates that he can carry the film, while Ms. Thurman makes what she can out of her smallish role. And who else would one cast as the authority figure in the enormous future techno-bureaucracy of the Gattaca Aerospace Corporation other than Gore Vidal?
The standout performance in the film, however, belongs to Jude Law. His performance of the crippled Valid unable to fulfill his predestined greatness, Jerome Morrow, is a remarkable combination of pathos, wit, and quiet resilience and strength, and his subtle blurring of the lines of identity between himself and Vincent is interesting. The strange, symbiotic relationship between Jerome and Vincent is fascinating and compelling, and Mr. Law and Mr. Hawke play well off one another.
While Jan Roelfs' top-notch production design assists in creating a dystopic and conformist world, the ultimate credit must go to Mr. Nicol. His screenplay is intelligent, thoughtful, and well-written, and his direction is most accomplished. The impressive GATTACA marks a science-fiction film which eschews effects and explosions in favour of a more fundamentally human story, and succeeds wonderfully. While the world depicted in the film is cool, distance, and impersonal, at the heart of the picture is real warmth.

--- layout: post title: "Terse operators make business code more readable" description: "Sometimes, terse operators can make code more readable. An article for all, even people who don't read Haskell code." date: 2018-07-02 12:00 UTC tags: [Haskell, Productivity] --- {% include JB/setup %}
{{ page.description }}
The Haskell programming language has a reputation for being terse to the point of being unreadable. That reputation isn't undeserved, but to counter, other languages exist that are verbose to the point of being unreadable.
Particularly, idiomatic Haskell code involves abstruse operators like .
, $
, <$>
, >>=
, <*>
, <>
, and so on. Not only do such operators look scary, but when I started writing Haskell code, it also bothered me that I didn't know how to pronounce these operators. I don't know how you read code, but my brain often tries to 'talk' about the code, silently, inside my head, and when it encounters something like =<<
, it tends to stumble.
At least, it used to.  When I read a piece of prose, my brain doesn't insist on 'saying' comma, semicolon, question mark, period, etcetera. Such symbols assist reading, and often adjust the meaning of a text, but aren't to be read explicitly as themselves.
I'm beginning to realise that Haskell operators work like that; sometimes, they fade into the background and assist reading.
As a word of caution, don't take this analogy literally. Each Haskell operator means something specific, and they aren't interchangeable. Additionally, Haskell enables you to add your own custom operators, and I'm not sure that e.g. lens operators like .~
or %~
make code more readable.
Forgetting about the lens operators, though, consider a piece of business code like this:
tryAccept :: Int -> Reservation -> MaybeT ReservationsProgram Int tryAccept capacity reservation = do guard =<< isReservationInFuture reservation reservations <- readReservations $ reservationDate reservation let reservedSeats = sum $ reservationQuantity <$> reservations guard $ reservedSeats + reservationQuantity reservation <= capacity create $ reservation { reservationIsAccepted = True }
Please read on, even if you don't read Haskell code. I'm not going to walk you through the details of how the operators work. That's not the point of this article. The point is how the operators enable you to focus on the overall picture of what's going on. The full source code is available on GitHub.
To establish a bit of context, this function determines whether or not to accept a restaurant reservation. Even if you've never read Haskell code before, see if you can get a sense of what's going on.
First, there's a guard
which seems to involve whether or not the reservation is in the future. Second, there seems to be some calculations involving reservations, reserved seats, culminating in another guard
. Third, the function seems to create
a reservation by setting reservationIsAccepted
to True
.
Granted, it probably helps if you know that both =
and <-
bind the left-hand symbol to the expression on the right side. Additionally, after all this talk about special Haskell operators, it may not be immediately apparent that +
is the perfectly normal addition operator, and <=
is the well-known less-than-or-equal relational operator. What if we keep those operators, and mask the rest with a white rectangle symbol (▯)?
tryAccept :: Int -> Reservation -> MaybeT ReservationsProgram Int tryAccept capacity reservation = do guard ▯ isReservationInFuture reservation reservations <- readReservations ▯ reservationDate reservation let reservedSeats = sum ▯ reservationQuantity ▯ reservations guard ▯ reservedSeats + reservationQuantity reservation <= capacity create ▯ reservation { reservationIsAccepted = True }
Finally, you also ought to know that while Haskell code is read from top to bottom, you tend to read each expression from right to left. Armed with this knowledge, and by masking the operators, the business logic begins to stand out.
First, it examines whether the reservation
is in the future, and it does a guard
of that. Again, I don't wish to make any claims that the code is magically self-documenting, because if you don't know what guard
does, you don't know if this expression guards against the reservation being in the future, or if, conversely, it ensures that the reservation is in the future. It does the latter.
Second, it conjures up some reservations
from somewhere, by first getting the reservationDate
from reservation
, and then passing that value to readReservations
(expressions are read from right to left).
Moving on, it then calculates reservedSeats
by starting with reservations
, somehow extracting the reservationQuantity
from those, and taking the sum
. Since we've masked the operators, you can't tell exactly what's going on, but the gist is, hopefully, clear.
The middle block of code concludes with another guard
, this time ensuring that the reservedSeats
plus the reservationQuantity
is less than or equal to the capacity
.
Finally, the function sets reservationIsAccepted
to True
and calls create
.
What I find compelling about this is that the terseness of the Haskell operators enables you, a code reader, to scan the code to first understand the big picture.
Additionally, some common motifs begin to stand out. For example, there are two guard
expressions. Because the operators are terse, the similarities stand out better. Let's juxtapose them:
guard ▯ isReservationInFuture reservation guard ▯ reservedSeats + reservationQuantity reservation <= capacity
It seems clear that the same sort of thing is going on in both cases. There's a guard ensuring that a Boolean condition is satisfied. If you, however, reconsider the actual code, you'll see that the white rectangle hides two different operators:
guard =<< isReservationInFuture reservation guard $ reservedSeats + reservationQuantity reservation <= capacity
The reason for this is that it has to, because otherwise it wouldn't compile. isReservationInFuture reservation
has the type MaybeT ReservationsProgram Bool
. There's a Boolean value hidden in there, but it's buried inside a container. Using =<<
enables you to pull out the Boolean value and pass it to guard
.
In the second guard
expression, reservedSeats + reservationQuantity reservation <= capacity
is a 'naked' Boolean expression, so in this case you can use the $
operator to pass it to guard
.
Haskellers may wonder why I chose =<<
instead of the more common >>=
operator in the first of the two guard
expressions. I could have, but then the expression would have been this:
isReservationInFuture reservation >>= guard
The resulting behaviour is the same, but I think this obscures how the two guard
expressions are variations on the same motif.
The use of operators enables you to express code in such a way that motifs stand out. In contrast, I tried writing the same business functionality in F#, but it didn't come out as readable (in my opinion):
// int -> Reservation -> ReservationsProgram<int option> let tryAccept capacity reservation = reservationsOption { do! ReservationsOption.bind guard <| isReservationInFuture reservation let! reservations = readReservations reservation.Date let reservedSeats = List.sumBy (fun r -> r.Quantity) reservations do! guard (reservedSeats + reservation.Quantity <= capacity) return! create { reservation with IsAccepted = true } }
While you can also define custom operators in F#, it's rarely a good idea, for various reasons that, at its core, are related to how F# isn't Haskell. The lack of 'glue' operators in F#, though, obliged me to instead use the more verbose ReservationsOption.bind
. This adds noise to the degree that the guard
function disappears in the middle of the expression. The motif is fainter.
Another motif in Haskell code is piping. This is known from F# as well, where piping is normally done from left to right using the |>
operator. You can, as the above example shows, also use the right-to-left pipe operator <|
. In Haskell, expressions are idiomatically composed from right to left, often with the $
operator, or, when using point-free style, with the .
operator.
Once you realise that expressions compose from right to left, a masked expression like sum ▯ reservationQuantity ▯ reservations
begins to look like a pipeline: start with reservations
, somehow pipe them to reservationQuantity
, and finally pipe the result of doing that to sum
. That's actually not quite what happens, but I think that this compellingly communicates the overall idea: start with some reservations, consider their quantities, and calculate the sum of those.
Another way to write that expression would be:
let reservedSeats = sum (fmap reservationQuantity reservations)
This implements the same behaviour as sum $ reservationQuantity <$> reservations
, but once you get used to it, I like the operator-based alternative better. The operators fade into the background, enabling the flow of data to stand out better.
Haskell operators constitute the glue that enables you to compose expressions together. Often, you need to vary how expressions are composed together, because the types are slightly different. Picking an appropriate operator that composes particular expressions enables you to perform the composition with a high signal-to-noise ratio.
Once you get used to reading Haskell code, the operators can fade into the background in well-factored code, just like punctuation marks assist you when you read prose. As always, this is no silver bullet. I've seen plenty of examples of obscure Haskell code as well, and copious use of operators is a fast way to obfuscate code.
Use; punctuation? marks with. taste!

Hey, Just wondering if its possible to have more than 3 CT's connected to the emonTX, are there additional analog input to extend this capability?
Basically I want to monitor many circuits in a building and try to get as many as possible connected on one board.
Thanks
Re: More than 3 CT's on emonTX
ADC 4 and 5 are free, see for yourself: http://openenergymonitor.org/emon/emontx/reference%20.
Yes you could build the energy monitor circuit on a bread/strip board and wire it into those free ports.
Re: More than 3 CT's on emonTX
Adding another two Analog channels to be sampled would reduce the accuracy right?
Re: More than 3 CT's on emonTX
Not at all, the Atmega328 on the emonTx spends most of its time sleeping. It would just sample each channel in turn at the same accuracy, and spend less time sleeping. Sampling one channel takes 332ms. Sampling 5 channels would take 1.67s + a bit more overhead for RF transmitting.
There is some info about this in the emonTx design notes: http://openenergymonitor.org/emon/modules/emontx/designnotes
Re: More than 3 CT's on emonTX
Okay Awesome! where on the pcb is the PWR/SER/12C pins. Is it the one below the emonTC sign (under the 2 blue capacitors and above the FTDI pins?)
Re: More than 3 CT's on emonTX
Yes, ADC4 is marked SDA and ADC5 is marked SCK. Their located just below the crystal and the two 2pF de-coupling capacitors.
Re: More than 3 CT's on emonTX
Couldn't find where I read that before, but I remember seeing somewhere that if you sample one channel, the time between measurements is very short (depends on the frequency at which you power the Atmega) and with each channel you add to be measured, the time between two measurements for each of the channels will get longer with each added channel. That's what I meant.

ssh: type/provider for ssh files for Puppet
This module provides a new type/provider for Puppet to read and modify ssh config files using the Augeas configuration library.
The advantage of using Augeas over the default Puppet parsedfile
implementations is that Augeas will go to great lengths to preserve file
formatting and comments, while also failing safely when needed.
This provider will hide all of the Augeas commands etc., you don't need to know anything about Augeas to make use of it.
Requirements
Ensure both Augeas and ruby-augeas 0.3.0+ bindings are installed and working as normal.
See Puppet/Augeas pre-requisites.
Installing
On Puppet 2.7.14+, the module can be installed easily (documentation):
puppet module install herculesteam/augeasproviders_ssh
You may see an error similar to this on Puppet 2.x (#13858):
Error 400 on SERVER: Puppet::Parser::AST::Resource failed with error ArgumentError: Invalid resource type `sshd_config` at ...
Ensure the module is present in your puppetmaster's own environment (it doesn't
have to use it) and that the master has pluginsync enabled. Run the agent on
the puppetmaster to cause the custom types to be synced to its local libdir
(puppet master --configprint libdir
) and then restart the puppetmaster so it
loads them.
Compatibility
Puppet versions
Minimum of Puppet 2.7.
Augeas versions
| Augeas Versions | 0.10.0 | 1.0.0 | 1.1.0 | 1.2.0 |

A$AP Rocky Plans To Design Uniforms For The Inmates In The Swedish Prison
by Alexis StoneNot too long ago, it was reported that A$AP Rocky had some pretty severe issues in Sweden where he was locked up. That’s the reason for which people were shocked to learn that he plans to go back for a performance before the end of this year, according to info coming from The Shade Room.
Now, TSR revealed that he’s shocking people once again and ‘reportedly designing prison uniforms for the inmates in the Swedish jail where he was held for six months.’
TSR cites the info from Forbes and says that ‘Rocky is trying to put his best foot forward and give back to Sweden after his arrest. In his first public speaking event since being arrested, Rocky attended a live conference called #Summit, where he reportedly explained his upcoming fashion plans.’
You can find out more details from TSR’s caption above.
People don’t seem quite impressed in the comments, as you will see for yourselves.
Someone said: ‘This is how you switch it around and make a 💰. The true definition of PAYBACK,’ while another follower said: ‘I can’t believe that was 6 months lmaooo thought it was a week.’
A commenter posted: ‘These celebs spend one night in jail .. now they got bright ideas for new colored uniforms! Yay !! 🙄’
Someone else is also unimpressed: ‘Why?? To make it cool to be in jail???? This world is lost.’
A follower said this: ‘Donate money to educational programs, empowerment workshops or activities you felt were lacking within their prison system…an outfit is one of the least significant things you can give someone to help them leave this experience better than they came. #Priorities.’
What do you think about A$AP’s latest decision?

Ebonyi govt house protocol staff arrested over alleged 17m fraud
Ogochukwu Anioke, Abakaliki
The Economic and Financial Crimes Commission (EFFC) has arrested one Miss Vivian Igwe, a staff of the Protocol Unit of the Ebonyi State Government House, Abakaliki, over alleged Seventeen Million naira(#17,000,000) fraudulent transactions.
She was arrested on Tuesday by officials from the Enugu zonal office of the commission in Abakaliki at the premises of the Ebonyi State Police Command.
The suspect who is about 25 years old was working as a typist at the Ebonyi Protocol Unit.
She was earlier arrested on Monday by men of the Special Anti- Robbery Squared (SARS) from the Area Command Abakaliki, at the Ezza Road branch of Ecobank in Abakaliki, the Ebonyi State capital, when she went to make a withdrawal.
The funds was said to had been transferred into her account by an unknown person about three weeks ago.
The Director of Protocol ,Ebonyi Government House, Nnenna Enyinnaya Okorie,while reacting to the incident said the suspect had earlier complained of her inability to make withdrawals from her Ecobank account.
She said the suspect had gone to the bank to apply for reactivation of her ATM card .
READ ALSO: FBI suspect jailed two years for $150,000 fraud
She explained that the bank officials had asked her to wait while they sort out her problems .
She said that it was while she was waiting for the problems to be sorted out that the police stormed the banking hall and arrested her.
She described the suspect as a very humble and honest staff and called for proper investigation of the incident.
“I am very surprised because this girl had asked me to permit her to go to her bank and ratify her account.
“She said that the most painful is the N1,500 sent to her by her sister which she said she had on several occasions tried to withdraw through her ATM card, but all to no avail.
“And she told me that she had not been getting alerts too. And the last information I heard from her is that she is going for the reactivation of her ATM as directed by the bank only to be arrested on Monday.
“And today Tuesday she was handed over to men from EFCC who came from Enugu” she said.
When contacted, Police spokesman in the state, Loveth Odah, said her office had not been properly briefed about the matter. Ends

What’s next for dual-weight world champion Katie Taylor?
Already a transcendent amateur, Katie Taylor is now 15-0 as a professional. In what was her ninth world title fight since switching to the paid ranks in November 2016, Saturday’s triumph means Taylor has become Ireland’s third ever dual-weight title-holder.
That honour comes off the back of another historic effort in June, when she defeated WBC queen Delfine Persoon to become undisputed lightweight champion. The victory at Madison Square Garden saw Taylor become just the seventh person in boxing history to concurrently hold all four recognised belts in one division. Including Saturday’s opponent Christina Linardatou, eight of Taylor’s beaten foes were — or have since gone on to be — world champions.
A long-awaited match-up with Amanda Serrano could well come to pass in 2020, the Puerto Rican herself a serial world champion. Taylor notably defeated her sister, Cindy, in October 2018.
Promoter Eddie Hearn has also expressed interest in carving a route for Taylor to become undisputed champion once again, this time at 140lbs. A rematch with Jessica McCaskill is, as such, a distinct possibility. The pair initially fought for Taylor’s WBA Lightweight title in 2017 at York Hall.
A crossover contest with Cecilia Braekhus remains in play, the long-time welterweight queen now also a Hearn recruit. That meeting would represent the first clash between two undisputed champions.
Calls for a Taylor-Persoon sequel still abound, the hard-fought nature of their first unification bout accentuating the appeal.

Performs a SIMD average of the packed unsigned integers from the source operand (second operand) and the destination operand (first operand), and stores the results in the destination operand. For each corresponding pair of data elements in the first and second operands, the elements are added together, a 1 is added to the temporary sum, and that result is shifted right one bit position.
The (V)PAVGB instruction operates on packed unsigned bytes and the (V)PAVGW instruction operates on packed unsigned words.
In 64-bit mode and not encoded with VEX/EVEX, using a REX prefix in the form of REX.R permits this instruction to access additional registers (XMM8-XMM15).
Legacy SSE instructions: The source operand can be an MMX technology register or a 64-bit memory location. The destination operand can be an MMX technology register.
128-bit Legacy SSE version: The first source operand is an XMM register. The second operand can be an XMM register or an 128-bit memory location. The destination is not distinct from the first source XMM register and the upper bits (MAX_VL-1:128) of the corresponding register destination are unmodified.
EVEX.512 encoded version: The first source operand is a ZMM register. The second source operand is a ZMM register or a 512-bit memory location. The destination operand is a ZMM register.
VEX.256 and EVEX.256 encoded versions: The first source operand is a YMM register. The second source operand is a YMM register or a 256-bit memory location. The destination operand is a YMM register.
VEX.128 and EVEX.128 encoded versions: The first source operand is an XMM register. The second source operand is an XMM register or 128-bit memory location. The destination operand is an XMM register. The upper bits (MAX_VL-1:128) of the corresponding register destination are zeroed.

"Kids"
by Ryan Kohler
"Kids" portends to inform America what their kids are "really" like. To do this, screenwriter (?), Harmony Korine, and director (double ?)  These characters include Telly (Leo Fitzpatrick), a would-be lothario whose idea of safe-sex is to do only virgins. As it turns out, he is HIV positive and has infected Jennie (Chloe Sevigny, a truly horrid actress). The movie then takes two paths: it follows Telly and his friend Casper (Justin Pierce) as they roam New York City, drinking, doing drugs, drinking, beating up a guy in the park, and drinking. It also follows Jennie as she attempts to keep Telly from infecting anyone else. Captivating stuff, isn't it? I didn't think so either. Perhaps things could have been better if Clark and/or Korine had a clue about film making. Clark, a photographer who evidently enjoys taking pictures of teens, shows the skill of Ed Wood in working a camera. I would assume, since "Kids" tries to have a documentary feel about it, that Clark wanted the viewer to feel like he was with these punks.  There is not one appealing character in this film, not even the alleged protagonist, or, perhaps, conscience, Jennie. Since much of the film revolves around Jennie attempting to stop Telly from infecting anyone else with HIV, Jennie's actions near the end of the film range on the pathetic and pointless. Chloe Sevigny (who almost single handedly ruined "The Last Days of Disco") brings a glazed look to her role as Jennie. She carries no emotions whatsoever: not as she waits for the results of her HIV test, not as she finds out she is HIV-positive, not as she talks to her girlfriends about things like sex. If an actress of some skill or talent had taken the role, perhaps Jennie would not have remained such a blank character.   Leo Fitzpatrick does nothing with the part. As his partner, Casper, Justin Pierce is just as crude and unbelievable. Harmony Korine's screenplay was, I guess, supposed to be a shocking expose.  Oh, it is shocking, alright: shocking in its ineptitude. There is no real structure, no reason for characters actions. It seems Korine just threw in whatever shocking events he could think of: rape, assault within an inch of a man's life, thievery, breaking into a public pool (okay, breaking into a pool isn't all that shocking, but still. . .) Maybe Korine should have heeded this lesson: shocks for sake of shocks generally don't work. It is well known that there are plenty of teenagers who think they are God's gift and can do no wrong, but, in truth, are complete frickin' idiots (my high school had a football team, so I can talk from experience.) There is certainly a film to be made that explores today's teenagers with frank honesty; perhaps that is the film "Kids" was trying to be. What comes out, however, is a pointless, meandering mess. "Kids" shocked me. It shocked me that a screenplay like Harmony Korine's could get bought. It shocked me that a studio would allow a director to spend their money without even demonstrating an ounce of skill or ability in film making. It shocked me to consider that, outside of Sharon Stone's body of work, there has rarely been such bad acting captured on film. Perhaps dear Casper said it best with the film's concluding line: "What happened?" My thoughts exactly, my friend, my thoughts exactly.
Rating: Not even worth a letter grade.

Latinum is a library for resource and money calculations. It provides immutable class Latinum::Resource
objects for dealing with quantities of named resources with an arbitrary number of decimal places, and class Latinum::Bank
objects for converting resources and formatting them for output. Latinum doesn't include any global state by design and thus is ideal for integration with other frameworks/libraries.
Motivation
I was originally planning on using the Money gem, but it's dependency on global state makes it hard to use if you want to deal with money as an immutable value type.
Additionally, I wanted to support BitCoin, Japanese Yen, etc. The money gem was heavily biased towards decimal currency. It had (~2012) fields like dollars
and cents
which don't really make sense and don't really align with the real world. These days they have fixed parts of the API, but it's a bit of a mess now, supporting both decimal and non-decimal values.
Another problem I had at the time was the concept of zero. It should be possible to have an additive (e.g. 0) and multiplicative identity (e.g. 1) do the right thing. In fact, in Latinum, you can multiply Latinum::Resource
instances by a scalar and get a useful result (e.g. for computing discounts).
Finally, because of the above problem, it was not obvious at the time how to sum up a collection of money instances correctly. In fact, this is still a problem and a separate gem, based on the Latinum::Collection
concept, was made. However, this all fits together in a rather haphazard way.
Latinum addresses all these issues. It has an immutable value type Latinum::Resource
which has a robust definition: A value (e.g. 5.0025) and a resource name (USD). The semantics of resources are well defined without the need for "Currency" state like the symbol, how many decimal places, etc. So, it suits well for serialization into a database, and for formatting to the user, there is Latinum::Bank
which gives you the choice of how you decide to format things or exchange them, whether you want to round something off, etc.

cenpy.products.ACS.check_match¶
-
ACS.
check_match
(self, name, level, return_level=False, return_table=False, cache_name=None)¶ A helper function to verify the match used by the product API.
- Parameters
- namestr
the name of the place/query string to be searched. Should be in the form “placename, stateabbreviation” (like “Los Angeles, CA”). For multiply-named locations, the format should be town1-town2, state1-state2, like Kansas City, KS-MO.
- levelstr
the name of the census hierarchy in which the name should be searched. Should be something like “Incorporated Places” or “States”.
- return_level: bool
Whether to return the level match. If you are uncertain as to which level the name is matching, set this flag to True to see the Census API layer that matches.
- return_table: bool
Whether to return the full table of possible matches for the queried name or level. If this is true, the return values are converted to be tuples, containing (match, table), where “match” is the entity in the Census API that matches the requested name or level, and table is the set of all possible values that could have been matched. If the matching fails for your first run, try inspecting table using return_table=True. Find the place/name you intend to match, and then input exactly that string.
- Returns
- ——-
- int
the row of the match table that records the matched name. If return_table is True, this becomes a tuple of (row, table). If return_level is True, the result is returned for both the match on the name and on the level. If both return_table and return_level are true, then two tuples are returned. The first contains the match for the name and the full table of possible names, and the second contains the match of the level and
- the full table of possible levels.
Notes
matches are made based on the partial_ratio and ratio scorings from the fuzzywuzzy package. The partial_ratio prioritizes the “target” being fully contained in the match. So, a string like Chicago, IL would be a perfect match for Chicago, IL as well as ‘North Chicago, IL’ or Chicago Heights, IL. If there are ties (which happens often), the ratio percentage is used to break them. This considers the full string similarity, so that the closest full strings are matched. This ensures that Chicago, IL is matched to Chicago, IL, and not West Chicago, IL.
Consult the fuzzywuzzy package documentation for more information on the partial_ratio and ratio matches.

sparse-vectors
Introduction
Sparse vectors are vectors that grow as large as they need to. That is, they can be indexed by arbitrarily large nonnegative integers. The implementation allows for arbitrarily large gaps by arranging the entries in a tree.
Usage
(require-extension sparse-vectors)
If you have the numbers extension installed then this extension will be built with an additional variant that supports bignum indices:
(require-extension big-sparse-vectors)
API
[procedure] (make-sparse-vector [DEFAULT])[procedure] (sparse-vector? x)
[procedure] (sparse-vector-ref sparse-vector k)
[procedure] (sparse-vector-set! sparse-vector k value)
[procedure] (sparse-vector->list sparse-vector)
make-sparse-vector, sparse-vector-ref and sparse-vector-set! are analogous to make-vector, vector-ref and vector-set!, except that the indices passed to sparse-vector-ref and sparse-vector-set! can be arbitrarily large.
The optional DEFAULT argument to the make-sparse-vector procedure specifies the default value for indices whose elements have not been set. If the element at index i has not been set, (sparse-vector-ref i) returns DEFAULT or #f, if DEFAULT was not specified when creating the vector.
sparse-vector->list is for debugging: It returns a list of the consecutive elements in a sparse vector from 0 to the highest element that has been set. Note that the list will also include all the #f elements for the unset elements.
(set! (sparse-vector-ref sparse-vector index) value) is supported.

This tutorial will go over more advanced plotting functionality. Before
reading this, you should take a look at the basic analysis and plotting
tutorial. First, we’ll load in some example data. This dataset is an
egg
comprised of 30 subjects, who each performed 8 study/test blocks
of 16 words each.
import quail
%matplotlib inline
egg = quail.load_example_data()
/usr/local/lib/python3.6/site-packages/pydub/utils.py:165: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)
accuracy = egg.analyze('accuracy')
accuracy.get_data().head()
| 0 | ||
|---|---|---|
| Subject | List | |
| 0 | 0 | 0.5000 |
| 1 | 0.5625 | |
| 2 | 0.1250 | |
| 3 | 0.5625 | |
| 4 | 0.3125 |
By default, the analyze
function will perform an analysis on each
list separately, so when you plot the result, it will plot a separate
bar for each list, averaged over all subjects:
ax = accuracy.plot()
We can plot the accuracy for each subject by setting
plot_type='subject'
, and we can change the name of the subject
grouping variable by setting the subjname
kwarg:
ax = accuracy.plot(plot_type='subject', subjname='Subject Number')
Furthermore, we can add a title using the title
kwarg, and change
the y axis limits using ylim
:
ax = accuracy.plot(plot_type='subject', subjname='Subject Number',
title='Accuracy by Subject', ylim=[0,1])
In addition to bar plots, accuracy can be plotted as a violin or swarm
plot by using the plot_style
kwarg:
ax = accuracy.plot(plot_type='subject', subjname='Subject Number',
title='Accuracy by Subject', ylim=[0,1], plot_style='violin')
ax = accuracy.plot(plot_type='subject', subjname='Subject Number',
title='Accuracy by Subject', ylim=[0,1], plot_style='swarm')
We can also group the subjects. This is useful in cases where you might
want to compare analysis results across multiple experiments. To do this
we will reanalyze the data, averaging over lists within a subject, and
then use the subjgroup
kwarg to group the subjects into two sets:
accuracy = egg.analyze('accuracy', listgroup=['average']*8)
accuracy.get_data().head()
| 0 | ||
|---|---|---|
| Subject | List | |
| 0 | average | 0.367188 |
| 1 | average | 0.601562 |
| 2 | average | 0.742188 |
| 3 | average | 0.546875 |
| 4 | average | 0.867188 |
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15)
Oops, what happened there? By default, the plot
function looks to
the List column of the df to group the data. To group according to
subject group, we must tell the plot function to plot by subjgroup
.
This can be achieved by setting plot_type='subject'
:
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='subject')
If you also have a list grouping (such as first 4 lists / second 4
lists), you can plot the interaction by setting plot_type='split'
.
This will create a plot with respect to both the subjgroup
and
listgroup
:
accuracy = egg.analyze('accuracy', listgroup=['First 4 Lists']*4+['Second 4 Lists']*4)
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='split')
Like above, these plots can also be violin or swarm plots:
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='split', plot_style='violin')
ax = accuracy.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='split', plot_style='swarm')
The Memory Fingerprint plotting works exactly the same as the the
accuracy plots, with the except that plot_type='split'
only works
for the accuracy plots, and the default plot_style
is a violinplot,
instead of a barplot.
fingerprint = egg.analyze('fingerprint', listgroup=['First 4 Lists']*4+['Second 4 Lists']*4)
ax = fingerprint.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='subject')
ax = fingerprint.plot(subjgroup=['Experiment 1']*15+['Experiment 2']*15, plot_type='list')
Like the plots above, spc, pfr and lagcrp plots can all be plotted
according to listgroup
or subjgroup
by setting the plot_type
kwarg.
listgroup = ['First 4 Lists']*4+['Second 4 Lists']*4
plot_type = 'list'
spc = egg.analyze('spc', listgroup=listgroup)
ax = spc.plot(plot_type=plot_type, ylim=[0, 1])
pfr = egg.analyze('pfr', listgroup=listgroup)
ax = pfr.plot(plot_type=plot_type)
lagcrp = egg.analyze('lagcrp', listgroup=listgroup)
ax = lagcrp.plot(plot_type=plot_type)
/Users/andrewheusser/Documents/github/quail_contextlab/quail/analysis/lagcrp.py:129: RuntimeWarning: Mean of empty slice
return np.nanmean(lagcrp, axis=0)
listgroup=['average']*8
subjgroup = ['Experiment 1']*15+['Experiment 2']*15
plot_type = 'subject'
spc = egg.analyze('spc', listgroup=listgroup)
ax = spc.plot(subjgroup=subjgroup, plot_type=plot_type, ylim=[0,1])
pfr = egg.analyze('pfr', listgroup=listgroup)
ax = pfr.plot(subjgroup=subjgroup, plot_type=plot_type)
lagcrp = egg.analyze('lagcrp', listgroup=listgroup)
ax = lagcrp.plot(subjgroup=subjgroup, plot_type=plot_type)
/Users/andrewheusser/Documents/github/quail_contextlab/quail/analysis/lagcrp.py:129: RuntimeWarning: Mean of empty slice
return np.nanmean(lagcrp, axis=0)


This is the default feature for the plugin. Each time a user inserts text into the input. Each entry will be store into an array that can belater use to restore its value.
This feature allows to keep the input values in the browser local storage. If you close or refresh the web page you could still have access to the input values
This feature uses the RESTful filosofy, so the values may be store in a database. If you use your browser debugger tool, you could see that the input is making a GET request when it initializes, an UPDATE request when you change the input's value and a DELETE request when using the deleteStorage() public method.

Simple house
Path: CARNOT/loads
Purpose
Simple(and fast) one node / one zone model of a house
with an integrated heating system. A neighbour building may be modelled by
using the same block or just as a constant temperature zone.
Description
The mathematical description of the house is the differential equation:
(m*cp)house * dThouse / dt = (UA)wall,roof * (Tamb - Thouse) + (UA)ground (Tground - Thouse) + (UA)neighbour (Tneighbour - Thouse)
+ shading * [ Gwindow1*Awindow1*Iglb,window1 + Gwindow2*Awindow2*Iglb,window2
+ Gwindow3*Awindow3*Iglb,window3 + Gwindow4*Awindow4*Iglb,window4 ]
+ (1 - eta) * Vhouse * nair * (Tamb - Thouse)
+ InternalGain * Aground + Qdotheatingsystem
The windows have an automatic shading (shading factor) if room temperature rises 4 K above initial temperature.
solar gain = Solar_Radiation_on_window * light_transmittance * shading_factor
The heating system is modelled by the equation:
(m*c)heating_system dT/dt = (massflow*cp)in(Tin- T) + UAheating_system * (Troom - T)
The heating system has a quadratic pressure drop characteristic:
dp = LINEAR * mdot + QUADRATIC*mdot2

Yusuf Ali offers 20 houses for Kavalappara rehabilitation
by Staff ReporterNRI industrialist M.A. Yusuf Ali has offered to construct 20 houses for those who lost everything in the landslip that claimed 59 lives at Kavalappara near Nilambur.
Mr. Yusuf Ali visited Kavalappara on Thursday along with P.V. Abdul Wahab, MP, and P.V. Anvar, MLA. He made the offer after listening to the woes of the people at Kavalappara. But the beneficiaries will have to find the land either from the government or on their own.
Mr. Yusuf Ali inaugurated the golden jubilee celebrations of Nilambur Orphanage at Amal College campus later. Veteran Congress leader Aryadan Mohammed and P.V. Anvar, MLA, spoke.
