Struggling to get everything outside a photo of the iPhone not to show. Learning about masks but not great at it.
Seems like there should be a way to select the extra bit with a wand, but even when I merge all the layers so I can do that, and copy the resulting bit, I don't know how to add that bit to the mask. I describe the problem in this little video:
Appreciate any tips!

Hi ajg23.
There are two ways of commonly masking things: masks (a.k.a. opacity masks, layer masks) and clipping masks. They work in different ways but achieve similar results. Although I'm a big fan of clipping masks, I'll stick to layer masks here as they are (in my opinion) a little easier to use.
A layer mask is a supplementary bitmap added to a layer (or group) that modifies its opacity. Where the mask is white, the layer (or group) is opaque, where it is black the layer (or group) is transparent.
Let's start with your unmasked image. Here's my 1 minute mock-up:
Let's add a mask to the group of objects. When you create a mask, it is affected by any active selections, so let's deselect before we do anything.
1. Cmd-D to deleclect.
2. Right-click on the group of objects and select Add Mask.
Now, you can paint on the mask itself.
3. In the layers palette click one the mask so that it is selected and in the canvas, with a sharp-edged black brush, paint out the bits you don't want.
Job done. If you go to far and paint out something you want to keep, switch to a white brush and paint it back in.
That's it, that's all you need to get this done, but I did mention something earlier about selections. If you have a selection active when you create a mask, rather than creating an all-white mask, Pixelmator will create a mask that is white where the selection was active and black everywhere else.
If you have a bit of time on your hands, now is the time try it. To remove your mask, right click on it in the layers panel and Remove Mask. Make the selection that you want then right-click and Add Mask again. If this isn't exactly what you want, you can always paint in/out more of the mask later. You may need to deselect first, though, as a selection will affect where you can/cannot paint.
Hope this helps. If anything is unclear, just come back and I (or someone else) will be bound to come back and help.

text: that the orbital ejecta of the Stickney crater that reimpact Phobos could be responsible for a particular subset of the observed grooves on Phobos. We adopt impact hydrocode iSALE-2D (impact-Simplified Arbitrary Lagrangian Eulerian, two-dimensional) to simulate the formation of the Stickney crater and track its impact ejecta, with a focus on orbital ejecta with launch velocities greater than the escape velocity of Phobos. The launch velocity distribution of the ejecta particles is then used to calculate their trajectories in space and determine their fates. For orbital ejecta reimpacting Phobos, we then apply the sliding boulder model to calculate the ejecta paths, which are compared with the observed groove distribution and length to search for causal relationships. Our ejecta trajectory calculations suggest that only ~1% of the orbital ejecta from the Stickney crater can reimpact Phobos. Applying the sliding boulder model, we predict ejecta sliding paths of 9−20 km in a westward direction to the east of the zone of avoidance, closely matching the observed grooves in that region. The best-fit model assumes an ejecta radius of ~150 m and a speed restitution coefficient of 0.3, consistent with the expected ejecta and regolith properties. Our calculations thus suggest the groove class located to the east of the zone of avoidance may have been caused by reimpact orbital ejecta from the Stickney crater.

The very faint companion star to Iota Sagitarii seen with SPHERE
The star HR 7581 (Iota Sgr) was observed in SPHERE survey mode (parallel observation in the near infrared with the dual imaging camera [left] and the integral field spectrograph [right]). A very low mass star, more than 4000 times fainter that its parent star, was discovered orbiting Iota Sgr at a tiny separation of 0.24". This is a vital demonstration of the power of SPHERE to image faint objects very close to bright ones.
The bright star itself has been suppressed almost completely by SPHERE, to allow the faint companion to appear as a clear bright spot to the upper right of the centre. This shows the great potential for SPHERE to detect exoplanets.Credit:

'Crushing' Evidence of Antiquity
Centuries before history began, someone left behind furnaces of ancient Old World Iron Age design buried deep inside "Indian mounds," hillsides and the banks of creeks in and around the land that would become Ross County, Ohio. Prehistoric Iron Age people from the Old World built the furnaces to smelt bog iron ore into wrought iron, the metal blacksmiths shaped into tools and weapons. I will provide conclusive proof that all attempts to fit Ohio's pit iron furnaces into the 18th century -- before American settlers claimed the land -- are unworkable. Instead, evidence indicates that these furnaces were constructed and used about a thousand years ago.
I was a teenage boy at Chillicothe High in Ross County when first I met Arlington H. Mallery in 1949. Scorned by professional archaeologists, Mallery, a bridge-building engineer, knew Iron Age furnaces when he found them, even if they occurred in Ohio, where they were not supposed to exist. He dug up several furnaces of ancient design along Ross County's Deer Creek in 1949-50.
I have developed compelling evidence these furnaces are in fact prehistoric and this new evidence will be uncovered in my new book, Iron Age America Before Columbus.

Adobe Flash animation, which starts with one large rectangle, which is divided
into four slightly smaller, which, in turn, are divided again, and so on.
The idea behind this animation is based on so-called quad trees used in computer graphics.
A virtual object consists of polygons: small flat surfaces. If the number of polygons is large enough, you will perceive the object as being a realistic representation of a real object.
To calculate whether a polygon casts a shadow, you need to calculate whether there is another polygon between the polygon and the virtual light source.
One way to do this is to check all polygons in the virtual space. Depending on the number of polygons, this will result in a huge number of calculations.
To reduce the amount of calculations the virtual space is devided into cubes. If a cube is empty, the subdivision ends, if a cube has virtual objects in it, the cube is devided again etc. etc..
Instead of calculating all polygons, first the enclosing cube is submitted to a calculation, if there's no intersection, there will not be intersection with one of the polygons inside that specific cube. This method allows to reduce the number of redundant calculations considerably.
In this case, the cubes are replaced by rectangles.
The rectangle is only divided if the colours inside the square differ from each other.
After some time, a pixel-art illustration will emerge.


updated in each YAML file. For each field marked, the automation process checks the image policy named, and updates the field value if there is a new image selected by the policy. The marker format is shown in the image automation guide. Within the spec of ImageUpdateAutomation, the Git commit branch and message can be customized.
Commit flow
Overview
A brief outline of the life cycle of a change as it's processed through Flux, centered around a Git commit:
 1. Bootstrapping Flux is the first step to get started using Flux.
 2. Generating a Flux resource with flux create ....
 3. Previewing changes prior to making or pushing a commit with flux diff kustomization.
 4. Automating upgrades through Image Update Automation resources uses Flux to generate commits when there are updated images available.
 5. Git as a Single Source of Truth means that Flux takes its instructions from a Git commit.
 6. Flux's default configuration for NetworkPolicy protects Flux services from arbitrary access across the cluster.
 7. Trigger Reconciling on Git push with Webhook Receivers.
 8. GitRepository and other Sources - Artifacts and Revisions.
 9. Secret Decryption via SOPS is performed if an optional decryption configuration is provided.
 10. Kustomize Controller builds and validates resources on the cluster through a server-side apply dry-run operation.
 11. Kustomize Controller applies changes with Server-Side Apply in stages, as an atomic transaction.
 12. Helm Controller reconciles HelmRelease resources through the Helm client library.
 13. Sources and HelmReleases generate HelmChart resources from a HelmRepository before HelmReleases can be installed.
 14. Using a GitRepository-backed or S3-backed HelmRelease is an alternative to use Helm without a HelmRepository.
 15. Channel-based Providers for Notifications re-publish Events from Flux resources at-large to a channel where users can see them.
 16. Git Commit Status Provider Notifications re-publish Events from the Kustomize Controller as commit checks.
 17. Waiting and Health Assessment for Flux Kustomization.
Bootstrapping Flux
Bootstrapping is the process of installing Flux so that Flux manages itself. This is the primary official supported way to install and use Flux.
We recommend all new Flux users start reading the documentation from Core Concepts, then follow the introductory guide, Get Started with Flux which covers bootstrapping Flux in-depth.
The bootstrap process installs all of Flux's core components to a cluster, as well as creating a GitRepository and Kustomization resource to keep all of Flux's deployed resources updated when any new changes are detected in Git.
Bootstrap also optionally connects with a Git host provider API if needed, to create a Deploy Key in the cluster and apply it to the repository so that private repositories can be used. Flux can be bootstrapped into an existing repository, or Flux can create the repository from scratch. The default bootstrap creates a private repository and generates a deploy key with read-only access for Flux, but there are many other configurations possible.
Once the repository is created and Flux adds its components there as a commit, bootstrap applies the Flux components and Custom Resource Definitions to the cluster, waits for the components to become ready, then applies the Flux sync resources (GitRepository and Kustomization) and finally waits for a successful reconciliation before reporting back to the user that this was successful.
Generating a Flux resource
After bootstrapping, the Flux CLI provides create generators to help users build more of Flux's Custom Resources that drive the operation of Flux.
flux create source git --help
flux create kustomization --help
These generators can be used imperatively to create Flux resources in the cluster, or as preferred: when called with the --export option, flux create ... can emit YAML on stdout. That output can be captured in a file, then committed and pushed to create the resource.
Following this process (rather than applying the resources directly to the cluster) maintains the manifests in the repository as the Single Source of Truth, according to GitOps principles.
Some resource options are not available through generators and can only be accessed through fields in YAML; users are generally expected to write resources in YAML and commit them, and should do so when they require access to those features.
For more information, see: flux create.
Flux's OpenAPI specification can also be integrated with editors to assist Flux users in producing valid YAML for Flux APIs; for a popular example see the Kubernetes Tools for VS Code. This method retrieves the OpenAPI spec from the cluster CRDs and doesn't require any special configuration for Flux.
Previewing changes
Users have an opportunity to inspect the result of Flux building manifests from a repository from the Flux CLI. This can be done ahead of where Flux actually applies it to the cluster, with flux diff kustomization / flux build kustomization.
Run flux diff kustomization --path=./clusters/my-cluster flux-system from the bootstrap repo, or point it at any other Flux Kustomization and the matching path in your configuration repository to observe what changes Flux will apply, even before they are committed and pushed. This takes account of the cluster state and so it can also be used at any time to check for drift on the cluster that Flux would revert back to the state in Git as soon as the Kustomization is reconciled, or at its next interval.
Any diff containing secret data is obscured so that no secret data is accidentally divulged from the diff output.
Automating upgrades through Image Update Automation resources
Flux can create Git commits to apply updates to the cluster, that are applied in the standard GitOps way to the cluster (as a Git commit), written by a Flux agent called Image Automation Controller. The Image Automation Controller with the help of the Image Reflector Controller works to determine when updates are available and apply them to the cluster.
ImageRepository and ImageUpdateAutomation resources, along with ImagePolicy, are documented in the image automation guide, and in the image automation API docs.

Git as a Single Source of Truth
Flux takes instructions from Git (or another source) which is meant to be the Single Source of Truth. Users create Git commits and push them to the repository that Flux is watching. Except when it happens as a result of Image Automation, the commit itself happens outside of Flux's purview. The source-controller pulls "commit data" into the cluster.
When the cluster reconciles a Source resource (like GitRepository or Bucket) the content in the new revision is captured on the cluster through a set of filters (.sourceignore, spec.ignore, …) and collected in a tar file to be stored; this file is known as an Artifact in Flux, and it can be accessed by any agent in the flux-system namespace.
When pushed, the receipt of a new commit activates the Git host to fire a webhook to notify subscribers about a push event, which Flux can consume via its Receiver API.
Flux's default configuration for NetworkPolicy
Arbitrary clients cannot connect to any service in the flux-system namespace, as a precaution to limit the potential for new features to create and expose attack surfaces within the cluster. A set of default network policies restricts communication in and out of the flux-system namespace according to three rules:
 1. allow-scraping permits clients from any namespace to reach port 8080 on any pods in the cluster, for the purpose of collecting metrics. (This can be further restricted when the metrics collectors are known to be deployed in a specific namespace.)
 2. allow-webhooks permits clients from any namespace to reach the Flux notification controller on any port, for the purpose of sending notifications via webhook when events are emitted from sources that the Notification Controller can be subscribed to with a Receiver.
 3. allow-egress permits agents in the flux-system namespace to send traffic outside of the namespace, (for the purpose of reaching any remote GitRepository, HelmRepository, ImageRepository, or Provider), and denies ingress for any traffic from pods or other clients


Men Who Pay For Sex Also In Debt To Society
For example, significantly fewer sex buyers, 47 percent against 70 percent, reported that they were taught about respect for women in sex education classes.
What's interesting about this study isn't that it found that men who buy sex are more likely to commit crimes; it seems like a redundant no-brainer that men committing a crimepaying for sex from a prostitutewere more likely to commit a crime. This also far from implies that every single man who has ever bought a lap dance is a Patrick Bateman-in-waiting, either. It seems that willful blindness to the plight of exploited sex workers is a symptom of a deeply seated problem in our society, and that there's no clear solution to eradicating the sexism at the root of it.
Men who buy sex tend to commit more crimes, survey says [Reuters]

Education is in demand by everyone, everywhere. So there are opportunities to open educational businesses even in rural areas, as Vusala Ahmadova, an entrepreneur from Azerbaijani city of Tovuz, knows firsthand.
Some years ago Ahmadova, an English teacher from north-west Azerbaijan, decided to open her own business, and started to cast around for opportunities. After a while, she settled on the area she knew best – education – and opened in Tovuz the branch of Edu Prime Education Academy.
This private educational institution offers various classes for children's mental and physical development, early development, and preparation for primary school. It offers a range of other subjects, including language classes, for which Ahmadova makes use of the experience she gained from years of studying and working as a teacher.
But first of all, to become an entrepreneur she herself had to take some training and work on her own skills. Only after that did entrepreneur have enough knowledge about the education business to be able to achieve success.
Providing financial stability
After taking some training, Ahmadova still felt she needed to boost here confidence in order to develop her new business. She was not sure if she would be able to hire more employees, provide them financial stability, and make her business grow. That's where the EU-funded project "Improved Support for Entrepreneurial Development in Rural Areas," part of the EU4Business initiative, came to her aid.
As part of the project, Ahmadova along with other woman entrepreneurs took part in training on self-assessment and improving self-esteem, gaining useful information for business planning and other important issues.
"I started almost everything from scratch, so I had a lot of difficulties, both financially and in terms of skills," Ahmadova says.
"In order to develop and move forward, I was constantly looking out for innovations, and I always joined in events and training. I've gained knowledge everywhere and am trying to apply it in my work."
Supporting women's entrepreneurship
The "Improved Support for Entrepreneurial Development in Rural Areas" project was launched on 8 May 2019. The overall objective of the project is to contribute to business development and employment generation across all economic regions of Azerbaijan, with a particular emphasis on improving rural livelihoods and the quality of life in rural areas. One important component of the project is focuses on developing the skills and confidence of rural women to enable them to become entrepreneurs.
Ahmadova heard about the "Improved Support for Entrepreneurial Development in Rural Areas," project from a friend and immediately decided to take part. The entrepreneur notes that the most valuable part of joining in the project for her was that she was able to gain knowledge and meet new people.
"I'd definitely recommend that other people take part in this type of project, because it creates self-confidence and helps strengthen your business," Ahmadova says.
"I have about 15 employees. The project has made it possible to provide income for all of them, which is a source of pride for me. Through the projects we join, we women entrepreneurs are supporting each other, connecting women working in different fields and helping them to find customers."

Determination of natural frequencies is essential to design offshore wind turbine foundations and is relevant to the stability of supporting structure. When the natural frequencies offshore wind turbine foundations are close to the external loading frequencies, excess deformations may occur due to resonance and lead to collapse of supporting structures. The natural frequencies of supporting structure change with foundation geometries, soil properties and structure stiffness. In the existing offshore wind farm in Europe, in most cases monopile foundations have been built as support structures for the wind turbine. To evaluate the natural frequencies and vibration responses of monopile foundation in the preliminary design of offshore wind turbine, a simplified method considered the pile-soil stiffness and deformation responses of supporting structure is presented in this study. The kinetic and strain energies of a structure system are applied to Lagrange's equation of motion to determine the natural frequency of monopile foundation. The natural frequencies of monopile foundation installed in soil with different properties can be determined quickly.

Nowadays, establishment and maintenance of turfgrasses due to high water requirements was faced with serious doubts. Hence, screening of drought resistance native grasses, and introduces them as turfgrass is not only effective in reduction of water usage but can also preserve plant gene pools of the country. In the present experiment, Wheat grass and Bromus as two native grasses were compared with perennial ryegrass as control. After establishment and coverage of the pots surfaces by turfgrass in outdoor, three mowing heights including 2, 4 and 6 cm were applied on the species weekly. During the experiment, shoot growth, tillering, leaf color and leaf width, fresh and dry weight were measured weekly. The results of this research showed that Bromus due to undesirable tissue (leaf width more than 3 mm) and low density is not suitable for use in landscape. Wheat grass despite of rougher texture and less color than perennial ryegrass, has higher tillering, suitable color (7.59) and good texture (leaf width about 2 mm). Also, mowing height of 2 cm was determined as the best for three species studied.

The aim is to pinpoint exactly how widespread the abuse of substances like mephedrone, commonly called meow meow, is by using a method of data collection that aims to filter out respondents who might not be telling the truth.
An international team led by scientists from London's Kingston University has developed a fresh approach to determining just how widely used designer drugs are. The aim is to pinpoint exactly how widespread the abuse of substances like mephedrone, commonly called meow meow, is by using a method of data collection that aims to filter out respondents who might not be telling the truth.
The researchers, led by Professor Andrea Petroczi, have devised a new form of questionnaire which is aimed at getting large survey groups to admit to behaviour which they might prefer to keep secret. The team found that up to one in 10 young people in the United Kingdom had taken mephedrone in the previous three months.
The team surveyed young people (with a majority aged between 18 and 27) in the London and Bangor areas using a new method called the Single Sample Count. The technique hides a sensitive question, in this case one about mephedrone use, among a series of seemingly trivial questions with yes or no answers, such as asking participants "Is your mother's birthday in the first half of the year?."
"In the past it has been shown that this kind of method always gives a higher rate of people admitting to drug use than if they're just asked outright," Professor Petroczi from Kingston University's School of Life Sciences said. "Another key feature of this simple method is that there is absolutely no way to relate the individual answers back to the respondents, so they are protected even if the researcher sees their anonymous response."
The results revealed that up to 10 per cent of the 318 young people questioned admitted using mephedrone at least once in the period leading up to it being classified as a class B controlled substance in April 2010. Before then, the laboratory-produced drug had been a so-called 'legal high'. It has a similar effect to amphetamines, ecstasy or cocaine. But it also causes nausea, palpitations and vomiting. The Office for National Statistics reported that there were six deaths involving mephedrone in 2010, the first year it had been mentioned on death certificates in England and Wales.
"The results are broadly consistent with similar studies into the prevalence of mephedrone and underline just how much of a problem the drug is with young users," Professor Petroczi said. "The proliferation of designer drugs is deeply concerning because of the very serious health risks. Drugs like mephedrone are usually untested in terms of exactly how dangerous they can be."
To help validate the questionnaire results, a new test for mephedrone in hair was also developed by Kingston University scientists. The results found that almost four per cent of the sample contained mephedrone, suggesting regular use.
"For the mephedrone to be detectable in your hair, it has to have been used more than once," Professor Declan Naughton, a co-author of the study explained. "So the figure is likely to be the habitual users, and the remainder of the 10 per cent figure from the questionnaire composed of those who have taken it just once."
A leading American expert in substance abuse said the Kingston research was significant. "Interestingly, mephedrone has not become well known in the United States at the moment, although that situation may change as time goes by," Professor Harrison Pope from Harvard University said. "Certainly the prevalence estimate of 10 per cent in the United Kingdom in this study is worrisome from our American vantage point, because it may point to rates of usage rising on our side of the Atlantic in the future too."
The study has been published in the journal Substance Abuse Treatment, Prevention and Policy and saw the Kingston University researchers work with colleagues from Bangor University, the University of Northern Colorado and Eötvös Loránd University in Budapest.

Why use niobium to make the cavities?
Each one of Jefferson Lab's 338 acceleration cavities cost about $30,000. A good portion of this expense comes from the use of niobium, a relatively rare and expensive metal. Why were the cavities made from niobium when they could have been made from a less expensive metal, such as copper?
Most metals are good conductors of electricity, but they aren't perfect. A property of metals, known as resistance, opposes the flow of electrical currents and converts electrical energy to heat. Unless the metal is part of something that is suppose to get hot (an oven, toaster, space heater or similar device), the heat is a waste product and adds to the expense of operating the device.
Jefferson Lab's cavities work by moving charges back and forth over its surface. This movement of charges is an electrical current. If Jefferson Lab's cavities were made from copper, the cavities would heat, expand and eventually melt. This would not be good for the accelerator.
There are two ways to avoid this problem. The first is to run the accelerator for very short periods of time and allow much longer periods in between for the cavities to cool. Unfortunately, this greatly increases the amount of time it takes to conduct an experiment. The second way is to eliminate the electrical resistance within the cavities. This is why Jefferson Lab's cavities are made from niobium.
Niobium, at room temperature, has electrical resistance and behaves just like copper. If, however, niobium is cooled to very low temperatures, it loses all electrical resistance and becomes what scientists call a superconductor. Since superconductors have no electrical resistance, electrical currents flowing through them do not lose any energy and do not produce any waste heat. If no heat is created, the cavities can not heat up and the accelerator does not need to shut down to allow them to cool. The use of superconductive niobium cavities allows the accelerator to provide a continuous beam of electrons to the experiments.
In order for niobium to become superconductive, it must be cooled far below the freezing point of water. The cavities are immersed in a bath of liquid helium at a temperature of -271°C (-456°F). This is only 2°C above absolute zero, the coldest possible temperature. The cavities and liquid helium are shielded from the heat of the outside world inside large, very well insulated containers called cryomodules.

Here's the best way to take down a Christmas tree:
1. Detach ornaments: Wrap them individually in tissue paper and return them to their boxes, or place them in sturdy plastic containers with cardboard dividers. Group the ornaments and label the boxes so next year you can find what you need easily.
2. Take down lights: Start where you finished when you put the lights up, and work backward. Wind each strand into a neat bundle, and place strands in separate plastic bags so they won't get tangled. Or wrap them on a spool (the way garden hoses are stored).
3. Take down the tree: If you used a plastic tree bag, envelop the tree and the stand, then take them outside. Once outside, remove the plastic and the stand, and discard the tree. If you haven't used a tree bag, take the tree out wrapped in a sheet. Or clip off the branches, bag them, and take them outside. Sweep up as many needles as you can, then vacuum the remaining dirt; needles aren't good for your vacuum cleaner.
Before you throw away the tree, you may want to remove small branches to use as mulch in the garden (or place the entire tree in a chipper-shredder to make a finer mulch). You may also wish to take your tree to a local recycling center.


Murdoch Stephens: NZers who welcome immigration should get off the fence
New Zealand is among the most welcoming nations on earth to immigrants and their cultures. Photo / Nick Reed
Last year saw plenty of opportunity to use the word "xenophobe" to describe people who are fearful of strangers and foreign people.
2016 was the year where the major English-speaking countries' voters turned inwards and away from the world. Brexit and Trump seemed synonymous with a fear and dislike of the foreigner.
The coming year will be different as we've already seen with international condemnation of Trump's ban on Muslim immigration. People can no longer sit on the fence. And so 2017 will become the year of the xenophile.
A xenophile is a person who has affection for, or is attracted to, foreign peoples, manners or cultures. Xenophiles like to explore the world and the people in it. They consciously put fears to the side because they know they would miss out on much of life if they avoided new experiences.
The difference between the xenophobe and the xenophile does not come down to the nation.
While most people associate xenophobia with nationalism and a dislike of foreigners, the prefix "xeno-" means stranger as well as foreigner. A xenophobe from Invercargill may have little time for Aucklanders.
There are all sorts of differences that trouble the xenophobe: skin colour, culture and religion are the obvious ones.
The fear at the heart of xenophobia is a fear of difference so you're likely to find a rural xenophobe disliking city people, or a sexist xenophobe fearing feminists.
Xenophiles are just as complex. Just because the xenophile is interested in other cultures it does not mean they don't love their own culture.
When we first hear of a kind of person who is the opposite of the xenophobe we might think of a person who fully adopts the culture of another country. But that sort of thinking has as much in common with the generalising of the xenophobe and is rarely sustained.
Xenophiles, by contrast, are happy in their own skin but are also attracted to the rest of the world.
It is the softer understanding of xenophile that will triumph in 2017: the love of other cultures for the languages, arts, foods and the refreshing new experiences that they provide.
It is at this point that an extreme xenophobe - or should we just call a racist a racist? - will point to the treatment of women in Saudi Arabia or of homosexuals in Iran.
Now aside from these xenophobes' genuine concern for feminist or queer rights - I don't doubt that for a second - the repugnant behaviours of one or two foreign countries will be generalised to argue that there exists an unbridgeable chasm between Islam and the Christian world, or the East and West, or just "us Kiwis" and "bloody foreigners".
In the "Double the Quota" refugee campaign, we sometimes witness the peculiar spectacle of xenophobes arguing against a fair increase in the quota based on other countries' treatment of women.
But our refugee intake privileges women-at-risk and families with children. Their fantasy of a refugee quota comprised of young Muslim men shows that these xenophobes know little about global refugee issues and are drawn to fear and hatred in direct opposition to the facts of the matter.
Is it a bit presumptuous to think that just a year after Trump and Brexit that 2017 would see the opposite focus on welcoming the stranger? Maybe. But those who think that the victory of Trump and Brexit indicate a generational movement of xenophobia and turning away from the world are missing an important point.
As with the anti-TPP protests in New Zealand, the antipathy towards globalism is more about economics than a dislike for foreign people.
Trump's win and Brexit both used xenophobic language, but the average voter seemed far more likely to point to the economy than immigration.
An Ipsos poll from September 2016 showed New Zealanders far more open to immigrants and refugees than 22 other countries. Part of this is because of the number of well-travelled New Zealanders, who were more favourable to being open to the world. We were the most likely country of all polled to agree that immigrants make the country a more interesting place to live.
The xenophile will triumph in 2017 for little reason more than New Zealanders have always been xenophiles. It's just that this year will be the first in some time that we will need an actual word to describe our openness to the stranger.

A little interesting about space life.
Have you ever wondered what may be the purpose of the moon? Well, the moon is the shiny beacon that lights up the night as the sun lights up the day. This amber body is quite shy and doesn't always show itself, but when it does, the moon's brilliance overpowers the darkness. The surface of the moon inspires astronomers around the globe who religiously watch as our incandescent orb passes serenely through its natural cycle, but if you are an avid planet observer you will come to realise that the reflecting light from the moon through the telescope lens may interfere with your ability to clearly view even our closest planets. For this reason many planet watches believe the new moon cycle is the perfect time to catch a glimpse of another world.

Dr. Jason Soderblom said in a September 10, 2015 Massachusetts Institute of Technology (MIT) Press Release that the evolution of lunar porosity can provide scientists with valuable clues to some of the most ancient life-supporting processes occurring in our Solar System. Dr. Soderblom is a planetary research scientist in MIT's Department of Earth, Atmospheric and Planetary Sciences in Cambridge, Massachusetts.
"Cassini's seven-plus years... have shown us how beautifully dynamic and unexpected the Saturn system is," commented project scientist Dr. Linda Spilker of NASA's JPL to Time Magazine's online edition on March 23, 2012.

New Moon in Scorpio. When Sun and Moon are in Scorpio, the most intensely felt sign of the zodiac with its deep undercurrents of passion, determination and will power it is not a time to go to sleep. Scorpio energy is driven by instinctual desires, deep unconscious motivations for control, domination and power. Scorpios are complex, charismatic and interesting people. They usually excel at where they choose to point their energy and you will always feel alive and kept on your toes around them. They will never be boring, but always a little mysterious and maybe feel just a little out of reach.
There is another aspect from the moon that is also going to improve your success and that is the moon rise and moon set. As a fishing angler you already know that some of the best times to fish are early in the morning and late in the evening the rising and the setting of the sun. Well the moon rise and moon set affects a fish's activity in the same way and since the moon has such a much stronger pull on the earth its effect is even more dramatic then the sunrise and sunset.

Hill climbing
Yesterday, I received the following email from Rob Taylor:
Dr. Robert, I've made an observation about a variation on the Gibbs sampler that hopefully would interest you enough to want to answer my question. I've noticed that if I want to simply estimate the mean of a unimodal posterior density (such as a multivariate Gaussian), I can modify the Gibbs sampler to just sample the MEAN of the full conditionals at each update and get convergence to the true posterior mean in many cases. In other words I'm only sampling the posterior mean instead of sampling the target posterior distribution (or something of that flavor). So my question is: Does modifying the Gibb's sampler to sample only the mean of the full conditionals (instead of the sampling the distribution) have any supporting theory or prior art? Empirically it seems to work very well, but I don't know if there's an argument for why it works.
To which I replied: What you are implementing is closer to the EM algorithm than to Gibbs sampling. By using the (conditional) mean (or, better, mode) in unimodal conditional posteriors you are using a local maximum in one direction corresponding to the conditioned parameter and by repeating this across all parameters the algorithm increases the corresponding value of the posterior in well-behaved models. So this is a special case of hill climbing algorithm. The theory behind it is however gradient-like rather than Gibbs-like, because by taking the mean at each step you remove the randomness of a Gibbs sampler step and hence its Markovian validation. Simulated annealing would be a stochastic version of this algorithm, using Markov simulation but progressively concentrating the conditional distributions around their mode.
4 Responses to "Hill climbing"
 1. […] the presentation of the first Le Monde puzzle of the year, I tried a simulated annealing solution on an early morning in my hotel room. Here is the R code, which is unfortunately too […]
 2. Your mention of simulated annealing / conditionals in this context got me thinking of my comment with Aline Tabet on Andrieu et al's recent read paper. To steal directly from the comment:
 Through PMCMC [particle Markov chain Monte Carlo] sampling, we can separate the variables of interest into those which may be easily sampled by using traditional MCMC techniques and those which require a more specialized SMC approach. Consider for instance the use of simulated annealing in an SMC framework (Neal, 2001; Del Moral et al., 2006). Rather than ﬁnding the posterior maximum a posteriori estimate of all parameters, PMCMC sampling now allows practitioners to combine annealing with traditional MCMC methods to maximize over some dimensions simultaneously while exploring the full posterior in others.
 It'd be interesting to study the properties of such an approach; as you say, it is perhaps closer to EM than MCMC.
 - If you replace mean with mode, you get Besag's interated conditional modes (ICM) algorithm that he developed in the context of Markov random fields.
 - This sounds like profile likelihood. But a more interesting interpretation would be to separate easily simulated parameters from harder-to-simulate parameters and to replace the formers by their MAP, in order to facilitate the exploration of the posterior of the latters… Interesting, indeed!

FIBA, the international governing body of basketball, has demonstrated its dedication to sustainability by unveiling an MVP trophy crafted entirely from 100% recycled materials. This significant initiative took place during the FIBA 3×3 World Tour 2023 held in Edmonton, Canada.
The design of the trophy was entrusted to Sustain Awards, and it has been meticulously crafted using sustainable methods and techniques, employing 100% recycled waste packaging as its foundation.
This innovative approach has led to a remarkable 75% reduction in carbon dioxide emissions throughout the trophy's entire manufacturing process compared to a conventional trophy. This encompassing reduction covers various aspects such as materials, packaging, and transportation.
Furthermore, this environmentally conscious process effectively offsets a total of five tonnes of carbon dioxide emissions (CO2e). This figure is equivalent to the impact of removing 397 cars from the road for a single day.
Alex Sanchez, the Managing Director of FIBA 3×3, emphasised the significance of this trophy in symbolising FIBA 3×3's strong commitment to reducing its carbon footprint. He expressed pride in being at the forefront of introducing an environmentally-friendly trophy, which stands as a testament to FIBA 3×3's dedication to sustainability and innovation.
Sanchez remarked, "Our objective was to create a trophy that had minimal environmental impact while evoking a sense of pride for its recipients. The introduction of this captivating MVP trophy reflects our achievement of precisely that goal."
Incorporating this groundbreaking MVP trophy represents a substantial stride forward for FIBA 3×3, resonating with the concerns of both players and fans regarding the well-being of our planet. The environmentally-friendly addition to the FIBA 3×3 World Tour 2023 is anticipated to garner widespread appreciation and acknowledgment.

Averages for Crete in March
March ushers in spring and is considered an unpredictable and varied month, as winter struggles to keep its grip on the island. For that reason, tourists visiting the island of Crete in March should be prepared for any weather – rain one minute, sunshine the next.
March sees average daytime temperatures floating around 14 degrees Celsius, with daytime high peaks reaching up to 17 degrees and lows going down to 10 degrees Celsius. The sea is almost constantly warmer than the air outside, with average seawater temperature staying around 16 degrees during the month of March. Expect 5 hours of daily sunshine on average. Crete experiences the regular winter-summer circle and March is a relatively rainy spring month. Total monthly precipitation reaches 62 mm and rainfall is expected during 8 of the month's days.
There are numerous local sayings about how March can be warm as summer one day and cold as winter the next, warning people about the unpredictability of the weather during this month. Hailstorms and even snow has been known to fall during March, alongside the rare phenomenon of winds carrying snow from the top of the Cretan mountains down to the beaches below.

Citrix Networking
To provide secure access to applications and desktops for external users, an on-premises Citrix ADC VPX or MPX appliance is required. Using smart cards with Citrix Gateway is a common access scenario for Citrix Cloud Government customers. This article describes Citrix recommendations for using smart cards with Citrix Gateway.
 1. Create a primary Gateway virtual server for authenticating users. Select the Client Authentication setting and set it to Mandatory. The Mandatory option enforces the need for smart cards by disallowing any SSL handshake that doesn't include a client certificate.
 2. Create a secondary Gateway virtual server that only handles ICA proxy. This Gateway is not configured to prompt for Client Authentication, so the SSL ICA connection doesn't prompt the user again for a PIN. In StoreFront, use this virtual server to route connections to resources. This allows users to log on to the primary Gateway, which handles the initial authentication, and access resources through the secondary Gateway.
 3. Create a third Gateway virtual server to provide the callback URL for StoreFront. Only StoreFront uses this Gateway to verify requests from the Gateway appliance and doesn't need to be publicly accessible. This virtual server is required when client certificate authentication is mandatory because StoreFront can't present a certificate to authenticate.

IPv6 Controllable Lighting
LOEUnit2IPv6 Controllable Lighting
Contestants: Tsuyoshi Momose, Tomiyasu Ohde, Yutaka Tatematsu, Toshihiro Imai
Affiliations: Cisco and DEP
The UPOE Light Over Ethernet unit make it possible to supply power to LED lights especially ceiling light in offices with Cisco developed high power PoE(Power over Ethernet), UPOE, which is on a way to a standard. Now the unit got IPv6 capability, that is, lighting system can become controlled/monitored from IP networks. This product would be the first step that everything in the world which was ever isolated from the network becomes internet reachable.
How does your Smart Object/Solution use Internet Technology?
At a glance, the LOE UPOE unit is just a fluorescent ballast, it has capability of IPv6, TCP and HTTP. IPv6 capability includes almost full set of neighbor discovery.
Why did you choose to invent this? What problem does the inventor see that it can solve?
There was already a product that supplies power with Universal POE for LED lighting system by DEP (_URL_). Though, it was using only layer 2 protocol, it means another server to control the units by the layer 2 protocol should be put on same broadcast domain. This is a restriction of network design of the LED lighting system.
Once the unit has IP capability, the unit can be controlled from anywhere and doesn't need any middle boxes to convert any protocols to the original UPOE LOE unit specific protocol. In addition, since IPv6 is implemented this time, you don't need to care address scope that some times require network address translation technologies.
What is the practical application of your innovation for the everyday user?
Lighting System. But the essence of this innovation was success of porting IPv6 onto PIC18F microcomputer which has just too poor resources but enough cheap to be embedded inexpensive commodity goods. This implies commodity goods could be IPv6 reachable in near future.
Did you invent new technology? How is your device unique?
Not invented much, but making the units (and lights) internet reachable is a great step.
What hurdles did you overcome in creating your device? Were necessary parts easily obtained?
The original device uses PIC18F micro computer as its controller. That was enough for the original usage when this hardware was planned. I ported Contiki OS to the micro computer. Contiki was well designed operating system for embedded systems, even though, Microchip PIC18F microcomputer's resource was too restricted.
Memory is just 3808 bytes which includes packet buffer (typically 1280-1500bytes per packet). Besides the packet buffer, the memory should be used for IPv6 address management, neighbor cache, TCP connection management, HTTP and socket buffer management, process status, real time clock counter so on. Moreover, the microcomputer architecture was something odd and development tool (IDE, debugger, compiler) was too buggy.
When I plan to ports Contiki OS to this chip, I thought memory was restricted but it would be possible to port relatively easy. Looking back, however, it was something tough way.
Anyway, IPv6 works on PIC18F at last, I'll put my work open source soon. I believe this make advance the rest of the world IP (actually IPv6) reachable.
Are there plans to produce your entry for the marketplace, or is it already a product that can be purchased/obtained?
The hardware itself is already in market.
The hardware sold here doesn't have IPv6 capability yet, but following the success of porting IPv6 implementation, DEP has started planning of selling IPv6 capability version now.
Why would you consider your device/solution to be "innovative"?
Not IT devices such as PC, Tablet and Smart Phone but building facilities that were used since a century ago become now internet reachable and supplied power with only single cable by the technology Universal POE.


Query plan
Query plan
Cypher is a declarative language, meaning that you specify what you want to retrieve but not the steps on how to retrieve it. Memgraph query engine determines the ideal way to execute a Cypher query. The big part of getting to the best execution time is having a good query plan structure consisting of query plan operators. If a query plan has already been generated for a certain query, query plan caching will speed up the execution. Besides the default behavior of the query planner, configuration can be tweaked to achieve the best performance.

Memgraph query engine is responsible for dealing with every Cypher query in Memgraph. It does not matter if the query comes from Memgraph Lab, mgconsole, or some other client.
A Cypher query is just a statement in the text that converts into a query plan for the database to understand and execute. There are several steps in that process, and here is a rough breakdown:
Query run initiated
Memgraph receives query as a raw string.
Query parsing
Query parser runs lexical and syntactic analysis.
Query planning
Query planner constructs an optimal execution plan and caches it.
Query execution
The storage engine executes the query plan.
Query results returned
Results are returned to the client that initiated the query.
First, you need to write a Cypher query. That step assumes an understanding of the syntax of Cypher query language. The Memgraph query engine is based on the openCypher defined in the full reference guide (opens in a new tab). There is a plethora of examples and help written on that topic.
Example
Let's give an example of how the query engine transforms a raw string into an actual result from the database. Here is the query:
MATCH (n:Node {id:1}) RETURN n;
The query is sent to the database, and as the first step it goes through is the query parser. The query parser will run the lexical and syntactic analysis of the query. That involves checking statements and query string structures, ensuring they are appropriately written and constructed from the available vocabulary.
Here is an example of a query that would not pass lexical analysis:
MATC (n:Node {id:1}) RETURN n;
The query parser will return an error because the MATCH keyword is misspelled:
line 1:1 mismatched input 'MATC' expecting {ADD, ANALYZE, CALL, CHECK, CLEAR,...
If the lexical and syntactic analysis goes well, the query engine checks if there is a cached query plan based on the same query.
If the query plan is found in the cache, it will be used for the query execution. On the other side, if there is no such query plan already cached, the query will be stripped of literals and replaced with normalized values for caching purposes. You can read more about that in the query plan caching section.
Query planner aims to find the optimal plan that defines steps for the most cost-effective query execution. Memgraph query engine can do many optimizations in the background but also make mistakes. Hence, it is essential to get familiar with the structure of a query plan to understand query execution and identify potential performance bottlenecks.
Query plan structure
To change the current plan structure, Cypher queries need to be updated, or some of the optimization techniques must be applied. The query plan is an internal tree-like data structure describing a pipeline of operations performed on the database to yield the results for a given query. Every node within a plan is known as an operator and describes a particular operation.
Because a plan represents a pipeline, the operators are iteratively executed as data passes from one operator to the other. Every operator pulls data from the operator(s) preceding it, processes it, and passes it onto the operator next in the pipeline for further processing.
Query plan can be obtained by prefixing any query with EXPLAIN or PROFILE clauses.
Example
Here is an example of a produced query plan:
EXPLAIN MATCH (n) RETURN n;
+----------------+
| QUERY PLAN |
+----------------+
| * Produce {n} |
| * ScanAll (n) |
| * Once |
+----------------+
The query plan should be read from the bottom to the top.
The output of the query using the EXPLAIN clause is a representation of the produced plan. Every operator within the plan starts with an asterisk character (*) and is followed by its name (and sometimes additional information). The execution of the query proceeds iteratively (generating one entry of the result set at a time), with data flowing from the bottom-most operator(s) (the start of the pipeline) to the top-most operator(s) (the end of the pipeline).
The resulting plan is a pipeline of 3 operators, as shown in the example above. Once is the identity operator, which does nothing and is always found at the start of the pipeline, ScanAll is an operator which iteratively produces all of the nodes in the graph, and Produce is an operator which takes data produced by another operator and produces data for the query's result set.
In this case, the ScanAll operator produces all nodes from the graph and passes them to the Produce operator, which returns the nodes to the user. This is a simple query data pipeline.
Here is a query that will generate the tree structure of the plan:
EXPLAIN MERGE (n) RETURN n;
Here is the generated plan:
+------------------+
| QUERY PLAN |
+------------------+
| * Produce {n} |
| * Accumulate |
| * Merge |
| |\ On Match |
| | * ScanAll (n) |
| | * Once |
| |\ On Create |
| | * CreateNode |
| | * Once |
| * Once |
+------------------+
Starting from the bottom and skipping Once operator, the Merge operator can take input from two operators - On Match or On Create. The results will be pulled from the On Match branch only if the matching node is found. On the other hand, the results will be pulled from the On Create branch only if there is no matching node, meaning a new node must be created. Each branch has its own pipeline of operators, starting with Once and being read from the bottom to the top.
Here is an example of a more complex query:
EXPLAIN MERGE (p:Person {name: 'Angela'})
ON MATCH SET p.found = TRUE
ON CREATE SET p.notFound = TRUE
RETURN p.name, p.notFound, p.found;
A more complex query will generate a larger tree-like structure:
+------------------------------------------+
| QUERY PLAN |
+------------------------------------------+
| * Produce {p.name, p.notFound, p.found} |
| * Accumulate |
| * Merge |
| |\ On Match |
| | * SetProperty |
| | * Filter (p :Person), {p.name} |
| | * ScanAll (p) |
| | * Once |
| |\ On Create |
| | * SetProperty |
| | * CreateNode |
| | * Once |
| * Once |
+------------------------------------------+
In the above example, each of the branches of the Merge operator has more operators in the pipeline. The On Match branch has a Filter operator, which filters the nodes based on the label and property, and a SetProperty operator, which sets the property on the node. The On Create branch has a CreateNode operator, which creates a new node, and a SetProperty operator, which sets the property on the node.
By combining different operators, the query engine can produce a wide variety of query plans that are data pipelines for executing queries and producing results.
Query plan operators
Each of the mentioned operators in the query plan represents a particular operation that will be performed on the data.
The following table lists all the operators currently supported by Memgraph:
OperatorDescription
AccumulateAccumulates the input it received.
AggregateAggregates the input it received.
ApplyJoins the returned symbols from two branches of execution.

Ecological and evolutionary consequences of mating system transitions in Arabidopsis lyrata
Most plants are hermaphrodites (simultaneously male and female) and therefore have a range of mating options spanning a continuum from self-fertilization to outcrossing (mating with a non-relative). The evolution of increased selfing allows plants to colonize new habitats, which may have different herbivorous and pollinating insects. This shift in the biotic environment alters natural selection for plant characteristics such as flower size and scent, and chemical and physical defences. This project aims to understand how these characteristic evolve as a result of transitions to self-fertilization. The study species is lyre-leaved rock-cress, Arabidopsis lyrata, a wild mustard which occurs throughout North America. There have been transitions from outcrossing to selfing in numerous populations of this species, allowing us to ask how this fundamental shift in reproduction has shaped adaptation to herbivores and pollinators. This research will allow us to understand the factors that shape plant diversity.

Desmin characteristics of CD11b-positive fibers after eccentric contractions
Medicine & Science in Sports & Exercise
First page number:
Last page number:
The purpose of this study was to determine the desmin characteristics of fibers infiltrated by CD11b-leukocytes in fast- and slow-twitch murine muscles after eccentric contractions.
We developed a computer image analysis procedure to quantify the percentage of intramyofiber CD11b-leukocyte infiltration. Only CD11b-positive fibers that exhibited identifiable borders were examined. Patterns of leukocyte infiltration of these fibers were distinguished and confirmed quantitatively by determining the mean percentage of leukocyte infiltration. We examined the desmin characteristics of these fibers with the same image analysis system and quantified the percentage of the fiber that demonstrated antidesmin staining. The influence of sex and muscle type on desmin characteristics and percentage of CD11b-leukocyte infiltration also was analyzed.
The percentage of CD11b-leukocyte infiltration was less than 50% for the majority of fibers. Three intramyofiber leukocyte infiltration patterns were identified that had significantly different mean percentages of leukocyte infiltration: 14%, 27%, and 47% (P < 0.001). Of the three desmin characteristics (normal, increased, and decreased) that were observed, almost three fourths of the fibers exhibited increased desmin. A significant difference in the percentage of increased desmin was found among the CD11b-leukocyte infiltration patterns (P = 0.01). Fibers with the least amount of CD11b-leukocyte infiltration showed the greatest amount of increased desmin. Sex and muscle type did not influence any of these findings.
Increased desmin appears to be associated with an early stage of intramyofiber leukocyte infiltration after eccentric contractions.

A reliquary with the blood of the early Church martyr St. Januarius is one of the treasures of Naples, Italy. The blood is said to miraculously liquefy at certain times of the year, including the Saturday before the first Sunday of May. Despite the lockdown of Italy, Cardinal Crescenzio Sepe reported that the miracle had happened May 2, and blessed the city with the reliquary via livestream.
"How many times our saint has intervened to save us from the plague, from cholera. St. Januarius is the true soul of Naples," Cardinal Sepe said.
The dried blood of St. Gennaro (his name in Italian), which is preserved in two glass vials in the Naples cathedral, traditionally liquefies three times a year: on the saint's September 19 feast, which commemorates his martyrdom in the Catholic liturgical calendar; December 16, the date of the eruption of Mt. Vesuvius in 1631, which was believed to have been halted through the saint's intervention; and the Saturday before the first Sunday in May.
St. Gennaro was bishop of Naples and is a saint and martyr of the Roman Catholic and Eastern Orthodox Churches. Historical sources claim he was martyred in the year 305 during the Diocletian persecution.
The blood relic of St. Gennaro, patron saint of Naples, also liquefied in the presence of Pope Francis during his visit to Naples on March 21, 2015; it was the first time the miracle has occurred in the presence of a pontiff since 1848.
The repeating miracle does not have official Church recognition.
In his homily, Cardinal Sepe warned about "another possible epidemic that worries me," speaking of the mafia. "There are those who are good at making a fortune in times of epidemic," he lamented.

Incorporating semi-precious stones and fine metals, her pieces are true statement jewelry. Her technique uses no soldering, gluing, or other methods to connect the components.


text: This survey is a study of fish commercialized in Forto Velho, Rondônia, Brazil from 1934 until 1989. The area studied is the Madeira river in a region of extensive gold extraction activity and therefore subjected to mercury contamination. The results showed that from the total fish yield, the fruiteating species ranged from 39.3% (in 1984) to 49.5% (in 1989). Among them, tambaqui (Colossoma macropomum) is the most captured mass. 22.9% (in 1939) to 32.5 (in 1936) of the species are detritivore and Curimata (Prochilodus nigricans) is the most important. Only 10.7% (in 1935) to 15.1%. (in 1934) are carnivore (Tucunare-Cichla spp and Pourada-Brachyplatystoma flavicans). The paper also deals with some of the ecological factors which can interfere with mercury accumulation in the food chain.

A Multilayer perspective for the analysis of urban transportation systems
- Publisher: Nature Publishing Group
(issn: 2045-2322, eissn: 2045-2322)
Physics - Physics and Society | Condensed Matter - Statistical Mechanics | Article
Public urban mobility systems are composed by several transportation modes connected together. Most studies in urban mobility and planning often ignore the multi-layer nature of transportation systems considering only aggregated versions of this complex scenario. In this work we present a model for the representation of the transportation system of an entire city as a multiplex network. Using two different perspectives, one in which each line is a layer and one in which lines of the same transportation mode are grouped together, we study the interconnected structure of 9 different cities in Europe raging from small towns to mega-cities like London and Berlin highlighting their vulnerabilities and possible improvements. Finally, for the city of Zaragoza in Spain, we also consider data about service schedule and waiting times, which allow us to create a simple yet realistic model for urban mobility able to reproduce real-world facts and to test for network improvements.
