EPA To Withdraw Proposed Extension of TSCA Title VI Compliance Date
EPA has indicated to CPA that it will be withdrawing the direct final rule that had proposed March 22, 2018 as the new TSCA Title VI compliance date. This week, EPA posted all nine comments received related to the proposed extension of the compliance date and at least one has been interpreted by EPA to be a "significant adverse comment." Under the rules of the Administrative Procedure Act, EPA must therefore withdraw the rule, which then reverts the compliance date back to December 12, 2017.
EPA had simultaneously issued a proposed rule with the direct final rule, which called for the exact same extension of the compliance deadline (March 22, 2018). CPA understands that EPA is still considering an extension of the compliance date under this proposed rule, and will be reviewing the nine comments received to make their determination. This process will take longer, as EPA will have to meet all of the internal review requirements prior to issuing a final rule. This likely will delay a final decision on the extension to later this summer. See Federal Register. More Info: Jackson Morrill

Since the creation of the Restoration and Conservation Department of the Polytechnic University of Valencia, Palomino's work in the church of Santos Juanes became a subject of study. Part of the wall-burned in 1936, were uprooted and later partially resituated the vault. Its condition has no solution to the present.
The constraints that needs this work required an special intervention. Chromatic restoration of the disappeared paintings and the almost conserved fragments representing 30% of the total required an alternative approach.
Once the first phase of color reintegration was carried out, the technical and conceptual solution has become a reference worldwide. In the words of Guianluigi Colalucci, restorer of the Sistine Chapel, "The work in Los Santos Juanes has achieved a feat ".
There was graphic historical documentation, a black and white image taken by photographer J. Alcon before the fire.
Using photography as chromatic reintegration material is justified by the fact that it is an objective approach to the original artwork. This way it's possible to avoid taking the character of a replace painting, so it's not a fake.
But does the condition of the art have the resources necessary to implement that image on naked mortars who lived with the surviving fragments?
The answer was NO.
This is the summary of the work carried out, especially since Arsus Paper makes a commitment to solve the technical challenge posed transfer a photographic image to the uneven surface and volume of the vault, respecting the need for mortar permeability. Taking into account both, the requirements of any proposed restoration of mural paintings.
The object of all the efforts of those involved was simple, in the words of José Luis Regidor, one of the project leaders, "is attempting to return to this work, part of the appearance that made her beautiful."
The approach designed by the architects of the project, where has laid the foundations of the system can be summarized in these sections:
Consolidation and restoration of the surviving fragments.Image processing:- Grinding, straightening and scaling of historical photography. - Color Management. Photography and treatment with HP Artist. - Color for the image in B / N.
Printing and transferring the image onto the wall. - Papelgel system.
Consolidation and restoration of the surviving fragments.
Definitive support. The plaster painting.
The principle of "similarity to the original" governing by the selection of materials used in restoration to guarantee compatibility (physical and aesthetic) and safety is one that has continued to the time of making the filling mural that was to receive the image transferred. This approach to prevail definitive nature of the support, traditional mural plaster, on the transfer system has been a challenge for the project.
First tests on the vault transfer.
For the selection of the final support for the transfer, the common pictorial plaster or filler mortars reintegration traditional for mural painting were studied, so, lime and sand mortar, plaster, etc.
The perfect scouring should just be a mortar as similar in manner and form that employ Palomino for execution of the artwork, so, a mortar of lime and sand. According to the analysis performed this would comprise lime plaster and marble dust ratio of 1/1 and 1/2 and a maximum particle size of 0.6 to 0.7.
After the evaluation and study of various proportions and variable, the decision was working with a mortar of lime and quartzite air in proportion 1/3 with a small addition of a crosslinking resin which improved tha shape of the ink reception in the transfer.
Image processing.
Grinding, straightening and scaling of historical photography.
The photograph of J.Alcón collects a particular three-dimensional space view of the dome of Los Santos Juanes. The image is shaped by several factors including the optics used, the location of the camera, the architectural form of the vault, etc. A meticulous study was necessary to obtain the correct interpretation of all this to unfold to a plane.
Georeferencing computer programs are used to locate an image in space. Basically is a match and recognizable selected points taken in the vault, which in this case would be representative points in the painting, with the corresponding photograph.
Once collected the data, and with the control points collected of the vault bound with a surveying station, are introduced into the program, the election to use the Microestation because it's a software that introduces a sub-program that may perform both tasks as remote sensing georeferencing called IRAS_C. The processing reconstructs the image to fit the control points. Modifies elastically, positions and holds the pixel coordinates.

Color Management. Photo capture and treatment with HP Artist Software.
The Hewlett-Packard has developed a tool created specifically for controlling and adjusting color digital reproduction of works of art, Artist program. At the time of starting the restoration work the software was still in testing phase. Technicals from HP I+D Division of large format photographs worked in Barcelona to process all the pictorial set of Palomino. The Artist system eliminates the uncertainty labor of manual color corrections. The integration of system components such as cameras, lighting and printers, reduces the time necessary to reproduce high quality precision work. No need to regulate illuminate artwork or color correction, the software automatically solves such problems during processing.
The software performs an automatic whites balance, corrects the illumination uniformity, chromatic corrections made and generates a TIFF file with an embedded ICC profile that is specific to that particular piece of art.
Color for the image in B / N. Digital painting.
The fragment corresponding to the working area of the photo in B / W of J. Alcon is expanded, and corrected, the actual size of Palomino presented frescoes in the vault, about 250 square meters. Certainly the great enlargement makes visible the silver halide particles comprising the photographic images, making of the image near lacks sharpness. But the whole painting will be seen from the floor of the temple, 26 meters away, reducing, in turn, the proportion of the observed.
To add color to the image of J. Alcon, firstly the photographic scanning has to be overlaped with the Artist software treatment. After adjusting the two images the selected areas of color photography and painting are not deleted. Obtained in this way two superimposed layers ready for digital colored phase in Photoshop program.
The color layer is desaturated to match and level the lights and shadows of a photograph of J. Alcon, adjusting the grayscale original photo in B / N, with respect to sweep color photography. Taking as a reference the colors of the original painting, transparent color layers are created as a glaze-color-singing until grays. Finally, the result is adjusted by increasing the level of detail to make the most number of pieces fit.
Assembly of the original fragments and photo in B/W.
aplication of color to the picture in B/W.
Final appearence of the image trasferred.
Printing and transferring the image onto the wall.
The technical challenge: just transfer the ink is not waterproof image to the wall.
The most important reason, apart from the desirability of the wall sweat, moisture balance inside / outside and avoid condensation, and keep it healthy, is that in the case of possible leaks inevitably dragged salts and the only way that would be available the precisely of the surface of the fragments preserved frescoes of Palomino.
The current state of the art features, with varying degrees of success, different solutions to transfer printed images, but so far to the different needs that require a mural as it has been explained maintain patency of the support.
Papelgel system.
Arsus Paper has developed a temporary support for transfer of inkjet printing. Starting from Papelgel ® Original, new development provides better control of the elasticity of the material. Furthermore, the new solid composition of the gel structure allows only the ink transfer photographic images printed on any surface, regardless of the texture, shape and porosity, without the need of special preparation of the support.
Transfer system with the new development Papelgel:
After the transfer process on the wall surface only the ink remains, and is compatibility with the definitive support will determine the safety and stability of the print.
Detail of a fragment.
The workshop of analysis and intervention mural from the Restoration Institute of Valencia Heritage (IRP) made a detailed study of the behavior of the pigment ink transferred onto plaster wall. This is a summary of the work carried out:
Several studies support the stability of inkjet prints with pigmented inks on various substrates, but are not aware of their behavior on lime mortars, since the application is unprecedented in the world.
The solidify system required to transfer the ink Papelgel liquid originally dry, on the temporary support, is dissolved again, and finally fixed on the wall surface. This change of state or the fact that the wall surface of lime and sand for a long time maintained a strongly alkaline pH (13), are factors that could alter the stability of the whole. To resolve these doubts were conducted studies that confirm the suitability of the structure pigmented ink / plaster wall.
A large number of specimens were subjected to artificial accelerated weathering cycles (UV illumination, temperature, humidity, polluted atmospheres) and therefore comparative chemical analysis such as assessment of changes color difference (DE *) and brightness were satisfactory, being for example more weakness in the wall bracket in the inks in the case of contaminated atmospheres test.
On the other hand, a comparative test was performed to check the abrasion resistance, which allow assessing how the structure reacts to factors such as erosion, friction, etc. The conclusion was that transfers generally have moderate resistance to abrasion compared to a fresco painting surface made, but very similar even carried over to dry surfaces with watercolor, which is the most used in restoration.
Chemical resistance test found that the transfers are sensitive to high polarity solvents such as toluene, and to a lesser extent to water. The oldest specimens, two years old, had the highest chemical resistance to the most recent, 3 months, that is, due to the gradual hardening of lime mortar as the binder curing inks, chemical resistance of transfers increases with time.
Conducted sponge contact absorber tests confirm objectively that the ink transferred is not a barrier to the natural breathability of lime and sand plaster. The methodology of the contact sponge-developed by CNR-Florence-ICVBC has been proposed as a simple and fast method to evaluate "in situ" the effectiveness of a water-repellent treatment on stone surfaces. The method is based on differences in weight according to the formula: Wa (g/cm2. Min) = (Pi-Pf) / 23.76 x t Where (Wa) is the amount of water absorbed during the test.

Chiropractic Care
What is Chiropractic Care?
Chiropractic care is a hollistic approach to treatment and primarily consists of manipulating the spine into proper alignment. The spine needs to be in perfect alignment in order for your body to recieve the regular transmission of nerve impulses. This form of care allows your body to heal naturally and is usually patients primary resource for low-back pain.
What Does Chiropractic Care Treat?
- Headaches
- Migraines
- Scoliosis
- Spinal Stenosis
- SI Joint Pain
- Golfers Elbow
- Degenerative Discs
- Low Back Pain
- Sciatica
- Neck Pain
- Herniated Discs
- Pregnancy
- Tennis Elbow
Flexion Distraction Table
Flexion Distraction is a chiropractic technique used to treat many conditions of the lumbar spine. It is a non-surgical technique aimed at increasing spinal motion and resolving disc bulges and disc herniations. The treatment is excellent as a safe, gentle, non-force procedure and works well to take pressure off the spinal nerves that may be injured or dysfunctional.
Flexion Distraction involves using a special table that distracts and flexes the spine in an automated and gentle rhythmic motion. The Chiropractic Doctor will use some manual techniques with the table to resolve the disc herniation or bulge. The goal is to allow the spine to move correctly in a manner that will remove pressure from the disc bulge. It does this by creating a negative pressure that pulls the disc bulge back into the spine. The flexion distraction motion also maintains healthy discs through imbibition. The motion allows nutrients into the spinal disc and keeps them well articulated.
- Reduce pressure on the spinal nerves from a disc bulge or herniation
- Increase spinal motion within the disc and spinal joints
- A conservative option to surgery for herniated discs
- Reducing symptoms of sciatica
Activator Technique
The activator technique is one of the most common therapeutic interventions used by chiropractors. The activator is a hand held instrument that delivers a low-force impulse to specific trigger points. Because of how quick this instrument is, the body's muscles do not have time to tense up. These low-force impulses help mobilize the spine and restore motion.
- Low risk treatment
- Increases mobility
- Relives pain
The drop table technique is a safer and more effective way to perform spinal manipulation. The drop table was invented after Dr. J Clay Thompson noticed that his patients were seeing favorable results when using a "dropped" head piece. After exploring the science behind why this could be, Thompson developed the table and accompanying technique that thousands of chiropractors use today.
- Increased strength
- Enhanced posture and performance
- Improved flexibility
- Improvement in sleep
- Increased resistance to injury
- Reduction in aches and pains
- Increased tolerance to stress
- Increase in the ability to relax
- General improvement in well being
- Chiropractic adjustments aid the body to heal itself without the use of drugs or surgery.

Invisalign for teens is a virtually invisible orthodontic treatment option which can straighten your teeth and improve your smile without anyone knowing you're having treatment – not even your friends, unless you tell them of course.
The treatment uses a series of custom-made aligners which are manufactured from clear, medical-grade plastic. They're safe to wear and comfortable because they've been specifically designed for your teeth using the latest 3D technology. But the best part of this treatment is that the aligners are removable. You can take them out to eat, brush and floss – and for a special occasion.
Invisalign for teens treatment starts with a consultation where we assess your teeth and take digital impressions of their position using our iTero® digital scanner. This gives us an accurate picture of where your teeth currently sit and how much movement is required to get you a perfectly straight smile. These 3D scans are then used to make your Invisalign for teens aligners, which look like thin sports mouthguards. Over the course of treatment, as an Invisalign® patient, you will be required to change your aligners every one to two weeks. Each new set has been manufactured in such a way to guide your teeth towards a straighter position. For optimal results, it is recommended you wear your aligners for 22 hours per day, so this gives you time to take them out for meals and snacks, sports practices, music lessons and when brushing after meals.
Traditional metal braces with their metal brackets and arch wires have been used in orthodontics for decades and for good reason. They get great results. But so too does Invisalign for teens. These aligners can be used for major and minor orthodontic cases and can achieve the same result as the traditional appliances.Other benefits of Invisalign® include:

Morris 52
A powerful passagemaker blends seagoing comfort with an elegant interior
The Morris 52 is the latest creation in designer Chuck Paine's striking Bermuda Series of high-performance offshore cruisers. "We've probably done 50 boats or so in the series, but most have been one-offs," Paine said. "The exciting thing about the Morris 52 is not only the extraordinary quality of the build but the fact that the boat is pulled from a female mold making it available on a semiproduction basis." The Morris 52 is inspired by Paine's earlier design, the Apogee 50, one of the first true performance cruisers. "The Morris 52 will deliver speeds of 10 knots or more in trade wind conditions, but can still be easily handled by a couple in their later years," he said.
Paine and Tom Morris have collaborated on some of the world's finest sailboats and the new 52 is another example of how to marry form and function. Paine's raised-saloon center-cockpit design achieves the advantages of light and space below without the bulky profile of an exaggerated pilothouse on deck. The hull shape features a long waterline, modest beam, stable hull sections and Paine's latest generation high-lift endplated bulb keel. Paine and Morris just can't seem to produce a sluggish cruising boat. Although the Morris 52 is engineered for crossing oceans and luxuriously appointed, sophisticated construction techniques and ultramodern materials keep the 52 surprisingly light-even loaded, the displacement-to-length ratio hovers around 200. When it comes to passagemaking, 200-mile days will be more the norm than the exception for this powerful sloop.
I recently hitched a ride on hull No. 1 for a SAILING boat test. Conditions were ideal as we cleared the Bayside Marina in downtown Miami, Florida, and made our way into the shimmering waters of Biscayne Bay. Owner Tom Brodie, a surgeon from Indianapolis, Indiana, couldn't wipe the grin off his face as his new boat accelerated smartly on an easy reach. The morning easterly was filling in, blowing at around 10 knots true as we glided south with the speedo flirting with 7 knots.
The details
The hull of the Morris 52 is a composite construction using ATC Core-Cell closed-cell foam sandwiched between layers of Kevlar E-glass laminates. Vinylester resin and ISO NPG gelcoat are used throughout the molding process. Stringers and floors are foam-cored fiberglass reinforced with unidirectional fabrics. The deck is also cored with Core-Cell, except in areas where fasteners are required where the core material is high-density foam. Structural bulkheads are marine plywood bonded to the hull and deck while nonstructural bulkheads are lightweight Decolite core panels-a perfect example of using superior materials to eliminate unnecessary weight.
The lead ballast is externally fastened to an integral fiberglass keel stub, which is the best possible arrangement, combining the advantages of internal and external keels. Vigilantly nixing unneeded weight from the deck and topsides allows for an extremely low center of gravity, a key factor in the excellent performance and seakindly nature of the design. Paine's highly efficient keel foil includes an elliptical bulb trailing into a T-shaped endplate to reduce turbulence created by water vortices, a technique developed by aeronautical engineers. The standard draft is 6 feet, 9 inches with a 5-foot, 11-inch shoal-draft optional. The spade rudder includes a carbon fiber post and upper and lower self-aligning bearings.
On deck
The cockpit of the Morris 52 is fairly compact, especially for a boat of this length, but quite functional. Hull No. 1 was fitted with a handsome teak wheel and a pedestal and steering system by Edson. The trunkhouse of the raised-saloon does not obstruct visibility and the sail controls are easily reached from the helm. The primary sheet winches are Harken 66s STC and the secondaries are Harken 53 STCs. While some center-cockpit designs leave you feeling a bit exposed to the elements, the Morris 52 cockpit is most secure. A rugged canvas and stainless spray dodger is standard and an optional stainless safety rail rimming the aft coaming makes an excellent handhold both in the cockpit and on deck. There is even a hint of a bridgedeck and two large scuppers will quickly remove any green water that does make its way into the cockpit.
The main halyard is led aft to an electric Harken winch located under the dodger. A Harken Big Boat traveler system is located just behind the cockpit providing efficient end-boom sheeting, an advantage of the center-cockpit layout. The mainsheet system is double ended. The standard genoa control system includes Harken Big Boat tracks set well inboard for tight sheeting angles with pin-stop cars. It would be nice to see an easier adjustable lead arrangement, especially because the furling headsail requires frequent lead changes. Husky 5-inch Harken double blocks mounted on angled stainless bases serve as the turning blocks, ensuring fair sheet leads back to the cockpit winches.
As expected, the deck hardware is top quality, beginning with the stainless stemhead fitting that is specially designed to accommodate a 60-pound CQR on the starboard roller and a 60-pound Bruce anchor to port. Teak handrails are standard and the Morris nonskid offers excellent traction, even when the decks are wet. The aft deck includes a lazarette, a dedicated propane locker and convenient access to the rather subtle stern step arrangement. While Paine's transom includes the de rigueur swim step, it blends naturally into the flow and is hardly visible when viewed in profile, a deft Down East approach on how to include this functional feature without distorting the boat's lines.
The standard aluminum spar has an air draft of just over 67 feet, but a waterway-optional rig reduces that figure to 64 feet, allowing you to sneak under the fixed bridges that span the Intracoastal, albeit with your heart in your hand. A Leisure Furl boom is standard along with a Forespar mechanical vang. The standing rigging is discontinuous rod while all running rigging is supplied by New England Ropes. A North Sails Soft NorLam full-batten mainsail designed for the Leisure Furl boom is standard along with a North 105-percent furling headsail. This small, just barely overlapping headsail provides plenty of power for the Morris 52 without the load and handling requirements of a larger genoa. An asymmetrical chute is the perfect compliment to the standard sail package.
Down below
"No yard anywhere in the world has the capability to build a more highly finished interior," Paine said. When you drop below on the Morris 52 you will probably agree with him; the interior is simply lovely. The saloon is flooded with light accentuating the rich cherry joinerwork with a satin finish. If you have something against cherry, Honduras mahogany can be substituted for no additional cost. And if you don't like mahogany, you can have any wood you want because as a limited production, semicustom builder, Morris encourages owner participation during the building process.
The 52 is available with two standard interior plans. Plan A includes an island double berth in the forward cabin with a separate head and plenty of floor space. There is a cork-lined hanging locker and bureau with beautifully made drawers. The saloon includes a wraparound settee and dining table to starboard with a settee opposite. Morris does a masterful job of blending luxury with function. The cabin sole, for example, is 5/8-inch Meranti plywood, vacuum bagged with 1/8-inch teak and basswood veneer overlay, creating a light, strong and handsome floor that can also be easily removed to access the bilge. The headliners are closed-cell foam laminates held in place with cherry battens. The windows in the saloon are made from laminated safety glass and include a slight, 7-degree bend that makes them significantly stronger-a classic Morris touch.
The forward facing nav station is tucked away to port with the electrical control panels mounted outboard. A quick inspection reveals an immaculate, well-organized wiring harness. A quarter cabin, or crew quarters, with upper and under single berths is behind the nav station. The galley is in the starboard walkthrough, another advantage of a center-cockpit layout. The double stainless sinks are to port, under the companionway and cockpit sole and three-burner Force 10 propane stove is outboard. There is plenty of counter space, nicely finished in Corian and the shelf space behind can be adjusted-a clever feature. An engine-driven Seafrost refrigerator and freezer with front-opening doors is standard and emphasizes the Morris 52's serious cruising intent. Engine-driven compressors are efficient and, most importantly, don't draw on the house batteries.
The aft cabin features an offset island double berth that allows for more floor space, and when combined with the mirror mounted on the forward bulkhead, creates a sense of spaciousness. Two hanging lockers and a host of drawers and shelves offer plenty of storage. The aft head includes a separate stall shower and Corian countertops. Ventilation throughout the boat is adequate, with stainless steel opening portlights and several deck hatches.
The Morris 52 is powered by a Yanmar 4JHE turbo-charged 100-horsepower diesel. A Tides Marine shaft seal is standard as is a three-blade feathering Max Prop. Two aluminum fuel tanks combine to hold 150 gallons of diesel, providing close to a 1,000-mile range under power. With the Morris 52's easily driven hull and efficient sailplan that's enough fuel to last a long, long time. The standard mechanical systems throughout the boat, from the Racor fuel filtration system, to the Whale deck wash down system, incorporate solid engineering and top-quality parts.
Under Way
Back in the bay, I finally wrestled the helm away from Dr. Brodie. We brought the boat up a bit, 50 degrees off the apparent wind, but instead of heeling we just accelerated. The trade wind was gaining momentum and we surged over 7 knots. The helm was extremely light, and although we didn't have much sea state, it was clear the Morris 52 is quite stiff. Cracking off onto a close reach with the apparent wind near 20 knots, we topped 8 knots, pretty impressive going for a cruising boat with a 105-percent headsail.
The sail control systems are very well thought out, and the loads are not excessive. Despite its size, the 52 is a relatively easy boat to handle. We spent some time experimenting with the Leisure Furl boom and tied in a reef for fun. Roller furling booms will soon become standard equipment on most new boats, they make sense and any early engineering problems have been overcome. I was impressed with the Leisure Furl boom's ease of operation. Coupled with the Harken headsail furling system, shortening sail is a snap. Just as important, making sail is also easy so you won't be tempted to get lazy and spend hours motoring on passage during squally weather
The Morris 52 is the result of an inspired design and brilliant execution. It is however, quite expensive, as quality always is. Still, if you have reached a point in your life where you desire to travel the world under sail and you don't want to compromise on performance or comfort, this just may be the boat for you.

Fans call Harry Styles' new song the new 'bi anthem'
Harry Styles' sexuality has been a hot topic for many years, ever since he said being female is "not that important" when it comes to finding the perfect partner.
He has also admitted in the past that he feels no need to define his sexuality.
"No, I've never felt the need to really [label my sexuality]," he said in an interview with The Sun last year. "No. I don't feel like it's something I've ever felt like I have to explain about myself."
However now, fans are wondering if he just came out as bisexual, with the release of his new song "Medicine".
Focus on the lyrics:
"The boys and the girls are here / I mess 'round a bit / And I'm okay with it / I'm coming down I figured out I kinda like it."
Fans are even calling it the "new bi anthem".
Some other lyrics in the song continue to suggest it too:
"Here to take my medicine, take my medicine/ Treat you like a gentleman."
We've never been more proud.
Harry has only sung his new song "Medicine" three times now, live, while he's been on his brand new arena tour.
Fans love the song so much that they've begun 'The Medicine Project', where they're spamming Harry's socials with the pill emoji to encourage him to release the studio version of the song.
Fingers crossed!

They soon formed a duo so that they can explore the jazz standard repertoire in a modern and original way as well as playing their original compositions. Core elements that define the duo are interactive playing, lush harmonies, emotional and virtuosic singing, rhythmic explorations and overall creative openness. In 2016, they played their first gig in London and since then, they have developed and promoted this project by expanding their repertoire, releasing some videos on YouTube and recording a few tracks in the studio. Their music encompasses many different elements, from moments of 'raging swing' to more open and free playing, including up-tempo numbers and more quiet, lyrical moments: Their music will lead you on a journey of deep emotion and joy.

I Built That
When I was younger–before the age of 10–my grandfather would take us fishing on the lake in his pontoon boat.
My sister and I learned it all–how to bait our hooks with worms and maggots, how to cast, and most importantly, how to wait.
You see, as any good fisherman knows, you can guess where the hot spots are and cast right in, but you can't always make the fish come to you. Sparkly lures may help, being there at the right time definitely helps, but since you can't see what's happening all the way down there underwater, all you can do is bait up, cast out, and be patient.
I remember my Pap telling me that I was a good fisher for that very reason–because I was patient.
"That's the most important thing," he said. "Bait your hook, then sit. Just wait."
Being a child who was on the quieter and more shy side, this came naturally to me then. (And it also caught me more than my fair share of bluegill.)
It was in those quiet moments I learned the value of ignoring the noise, and focusing on just one task at hand.
But somewhere along the line in the ensuing years, as I grew up from being that little girl on the pontoon boat, I also grew more restless, more impatient in my ways. I could still sit still if I had to, but it didn't come as naturally to me as the pressing duties of school, then work and motherhood, started in.
So this past weekend, when we bought our two big kids Lego sets and the first thing my daughter asked when we got home was for me to build it, you can guess what my first impulse was to say.
"No, honey, your dad will help you with that later."
After all, dinner wasn't going to make itself and the toys couldn't put themselves away and the laundry is in that state where it's just about to be a real pain in the butt to fold if I don't hop on it right away.
I don't know if it was the sweet look on her face when she asked, or maybe the twinge of disappointment I detected when I said no, but I immediately went back on my words. I knew. It was time to slow down, to go back to being that girl on the pontoon boat for a second, to sit down, cast out and be patient. It was my time to enjoy the moment with my little girl.
We sat down and I built this. The first ever Lego set I've constructed:
I'm damn proud–not only of what I built, but also of the fact that I put aside time for my girl. That I was patient with myself, took the time to see something through, granted myself he grace to ignore the clutter, and built the damn Legos.
For a few minutes, I reconnected with the girl on the boat who knew instinctively that the best things in life need time and patience. And sometimes, no matter what tasks are calling your name, you just have to just sit and enjoy the moment.
And I have this set and one happy little girl to prove I made the right call.
P.S. A few ways (that don't involve Legos) to maximize your relaxation, and my unprofessional advice on surviving the early days of motherhood.

A Forward Operating Base is to be constructed for the military at Enzulebu in the Ellembele District, Western Region for the protection of the nation's oil resources, President Nana Addo Dankwa Akufo-Addo, has announced.
He said the government had signed a contract with a firm for work to begin on the project while the Ministry of Defence and the Ghana National Petroleum Corporation (GNPC) had also ordered six patrol boats to augment the fleet of the Navy as part of moves to protect the nation's maritime resources and oil fields.
President Akufo-Addo, who is also the Commander-in-Chief of the Ghana Armed Forces (GAF), announced this at the 2018 graduation ceremony for Regular Careers Course 58 and Short Service Commission/Special Duties Course 56 at the Ghana Military Academy in Accra yesterday.
In all, 138 cadet officers, including two allied officers from Guinea, passed out.
The overall best award also known as Sword of Honour went to Junior Under Officer S. A. Appiah.
A female Junior Under Officer, Ms Akosua Serwaa Appiah, took two awards: the Chief of Army Staff's Award and the Military Cane.

Addressing the gathering, the President said the government planned to construct a new military training school to meet the requirement of the 21st century.
He explained that since its establishment in 1960, the school had not witnessed any major improvement in its infrastructure while the land on which the school was located had also been encroached upon.
President Akufo-Addo said if the newly inducted officers had the impression that their toughest time was the training they endured, they would be facing tougher challenges which would require the expertise they had acquired to deal with.
He urged the newly commissioned officers to be guided by the motto of the academy, which was, Service, Devotion and Sacrifice, to ensure it remained their guiding principle in life.
The President said the government had provided 50 high occupancy buses for transporting personnel for training aside from the 40 pickups supplied in 2017 for Operation Calm Life.
He disclosed that the government had ordered 135 vehicles, including Pickups and Land Cruisers, which would arrive within the next two months to augment the vehicular fleet of the military.
The President announced that the second phase of the asphalting of roads at the various barracks would begin very soon.
He said the sector minister would cut the sod for the commencement of the Commander-in-Chief Sports Stadia across the country beginning with the one in Tamale, adding that already funding had been secured for the new Army headquarters which would begin before the end of the year.
President Akufo-Addo urged the commissioned officers to guard against the temptation of using their uniforms to intimidate civilian counterparts who were their natural partners in the development of the nation.
He reminded the military that it was the taxes of the civilian population that provided the means for the sustenance of the military and urged them to execute the qualities of good politics instilled in them at the academy and lead exemplary lives.

Last Night in Pittsburgh
Tonight is my last night as a resident of Pittsburgh. Well, at least for the time being. I haven't been this emotional about something for quite a long time.
I've always loved Pittsburgh. When I was a kid I loved coming to town for Penguins games. When I was a young punk-rock teenager I loved coming to town for punk rock shows (and even more Penguins games.) I've always just had a place in my heart for this amazing town. When the chance to move to Pittsburgh made itself available quite a few years back, Val and I jumped on it. It's been one of the better decisions we ever made.
We've made so many great friends here and have done so many neat things. Some of my favorite things:
- Refresh Pittsburgh
- Web Design Day
- Stanley Cup Finals
- Super Bowl Victories!
- The Rise and Fall of the Creative Treehouse
- Having the worlds dumbest conversation at PodCamp Pittsburgh that resulted in us creating a term called bacn that ended up in the dictionary.
- Fantastic metal shows at Kopecs.
- Aiello's and Mineo's Pizza
- Station Street Food
- Franktuary
When I pull out of town tomorrow, I'm going to regret leaving Pittsburgh. But not nearly as much as I would regret not taking advantage of the fantastic opportunity I have to work with some of the smartest and nicest people in our industry. I'm ready to do my best and see what we can do.
There is no one else I would go on this adventure with than my wife Val. If it wasn't for her, I probably wouldn't be able to do something like this on my own. I'm about as introverted as they come – but Val is the best thing that ever happened to me. If it wasn't for her just being my best friend, I would probably be at coding shitty html emails is some corner of Buffalo, NY.
We'll still be in Pittsburgh a lot – so we can still hang out with pals from time to time. I plan to still come home for plenty of Pens games too. Web Design Day will still stick around. We won't be strangers.
We'll also be back. Pittsburgh is home. We'll be away for a while but I'm sure it will be home again soon.

The Arsonist (Vintage Contemporaries)
Language: English
Pages: 320
Format: PDF / Kindle (mobi) / ePub
After fifteen years working in East Africa, Frankie Rowley returns to the New Hampshire village where her family has always spent their summers. But the tranquility she's expecting proves short lived when, on the very night she arrives, a mysterious arsonist begins targeting the homes of other summer residents. As this seemingly idyllic community becomes increasingly on edge, Frankie also has to deal with her father's declining health—and begins a passionate affair with the editor of a local paper that will yield its own remarkable risks and revelations. Suspenseful, sophisticated, and finely wrought, The Arsonist is an artfully nuanced and deeply emotional novel about a family and a community tested, about how and where one ought to live, and about what it means to lead a fulfilling life.

By Michael Allman, Staff Engineer at VideoAmp
For Spark 2.1, VideoAmp collaborated with Databricks and the wider Spark developer community to reduce the initial time to query Hive tables with tens of thousands of partitions from minutes to seconds. We also eliminated the need to fetch existing metadata when new table partitions are added. Together, these features bring Spark SQL rapid access to huge, evolving data warehouses—a key technical requirement for VideoAmp. Databricks and VideoAmp have written a joint blog post with technical details and benchmarks at https://databricks.com/blog/2016/12/15/scalable-partition-handling-for-cloud-native-architecture-in-apache-spark-2-1.html.
In this post, we'll describe our motivation for developing this feature and provide additional benchmarks. We'll also describe a problem we encountered running some of our queries while testing this feature internally, how to identify that problem in your own queries and how to work around it until it is fully addressed in Spark.
Some Background and Motivation
VideoAmp has been using Spark SQL from the inception of our data platform, starting with Spark 1.1. As a demand side platform in the real-time digital advertising marketplace, we receive and warehouse billions of events per day. Most of these events come as large JSON documents, which we store with full fidelity as partitions in one of our Spark SQL event tables. We now have tables with tens of thousands of partitions. We routinely trim a month of partitions from our largest table once it reaches 100,000 partitions.
Spark caches table metadata on first access for rapid query planning on subsequent accesses. Prior to 2.1, Spark fetched all partition metadata as part of its table cache. Additionally, adding a new partition to a table evicted that table from the metadata cache. Our largest tables are updated 10 to 20 times per hour, effectively negating the benefits of the table cache.
Our first solution to this problem took a shortcut—rather than fetching all of a table's partition metadata, we fetched just the partition names. Because we use the standard layout for Hive table partitions, we can infer the location of a partition from its name. Fetching a table's partition names from Hive is an order of magnitude faster than fetching their full metadata (the SHOW PARTITIONS command uses this faster API in Spark 2.1), and this reduced our planning times from minutes to seconds.
Eventually our tables reached multiple tens-of-thousands of partitions, and we began to hit the scalability wall again. We began to prototype a new approach based on deferred partition metadata loading. At the same time, we approached the Spark developer mailing list to sound out our ideas. Shortly thereafter, we submitted one of our prototypes as a pull request to the Spark Github repo. That began our collaboration to produce Spark 2.1's new features for large partitioned tables.
Spark 2.1 separates table and partition metadata caching, and it only fetches partition metadata as-needed. That is, when Spark 2.1 plans a SQL query it computes and caches exactly the table partitions needed to satisfy the plan. The complexity of querying a partitioned table is now based on the number of partitions read versus the number of partitions in the table.
We've benchmarked several queries from our data-to-day workload and selected two of them to illustrate the performance difference between Spark 2.0 and Spark 2.1.
Average CPM
Average CPM is our average cost to purchase an ad impression over some time window. This is a KPI for any demand side platform. The table over which we run this query has about 18,500 partitions.
Supply Query
Our supply query is an hourly aggregation summarizing facts about the ad purchasing opportunities we receive from our partner exchanges. This is a wide query with thirty output columns, multiple aggregate function calls over multiple groupings and a union of two subselects. We populate a new partition of a Spark SQL data mart with the results of this query, which typically produces about fifty million rows per hour. It reads from two tables with a total of about 71,000 partitions.
We ran our benchmarks on independent EC2 clusters, each configured with 4 c3.8xlarge workers. This equates to 128 cores and 240 GiB of memory per cluster. We ran one executor per worker, using all cores and configured with 16 GiB of heap.
Our first benchmark splits the Average CPM query running time into execution and planning components. We ran this benchmark for a month, week and day of data. In Spark 2.0, planning time is relatively constant at 14 seconds for all partition selections, as expected. In Spark 2.1, planning time is hardly measurable, and the difference in query time between the two versions as we query fewer partitions becomes more substantial.
The results of our supply query benchmark tell a similar but more dramatic story. We ran this query on an hour of data, just as we do in production, twice in a row. On Spark 2.0, planning takes more than 66% of total query time for both executions. On Spark 2.1, planning takes 2.6% of total query time in the first run and no measurable time on the second run. We can see here Spark 2.1 is caching and reusing partition metadata collected from the first query execution. However, Spark 2.0 fetches the entire table's partition metadata in both the first and second execution, contrary to our initial expectations. However, we realized this query takes so long to execute (about 15 minutes) that between the start of the first run and the start of the second, our warehousing process has already added a new partition to the underlying table. Since Spark 2.0 invalidates a cached table if *any* of its partitions change, it cannot reuse the metadata it cached as part of the first query execution. This mirrors our early experience with Spark 2.0 running ad-hoc queries on our largest tables, where each query came with a several minute overhead.
Unsafe Broadcast Join Conversions
While testing pre-release builds of Spark 2.1 internally, we encountered some cases of unsafe automatic broadcast join conversions where we had not before. To review, if Spark estimates that the data for one side of a SQL join will fit within a certain size threshold (set by spark.sql.autoBroadcastJoinThreshold), it will broadcast that data to all of the executors and put it in an in-memory hash table for rapid lookup.
In previous versions, Spark used the file size of all of a table's partitions in estimating a query plan's size. This could easily result in query data size overestimations. Now Spark only includes the partitions read as part of a query in its size estimate. This is more correct than previous behavior, however in some cases it can lead to an automatic broadcast join conversion that will attempt to broadcast much more data than the cluster can handle.
This problem will manifest itself as heap OutOfMemory errors or excessive garbage collection in the driver process. If you suspect a bad query size estimate, set spark.sql.autoBroadcastJoinThreshold=-1 (which disables this optimization) and retry your query. If it succeeds, chances are Spark is attempting to broadcast more data than it can handle in-memory.
A definitive diagnosis can be made with a relatively simple procedure. First, make a note of your default spark.sql.autoBroadcastJoinThreshold, and identify which side of the join is being broadcast by examining the query execution plan. Set spark.sql.autoBroadcastJoinThreshold=-1 and run your query again. Once it finishes, open its detail page in the SQL tab of your app's UI. There should be an Exchange stage in the query execution diagram before a SortMergeJoin or ShuffledHashJoin. Look for a statistic called "data size total". If this value is significantly larger than your automatic broadcast join threshold, you've found the problem.
This issue has been reported as https://issues.apache.org/jira/browse/SPARK-18676 and work is underway to fix it. At the time of writing, steps have already been taken to decrease the likelihood of this issue occurring for the Spark 2.1.0 release.
Overall, we're excited to see these capabilities brought to Spark 2.1 and believe they will enable further integration of Spark into environments with large Hive data warehouses.

Podcast: How to Stay on the Leading Edge with Kootenay Co-op
You might think the bleeding edge is populated with high tech start-ups, but there are folks out there leading their respective packs you may have never thought of. Take grocery stores for instance.
So much more than just a mere grocery store the Kootenay Coop has grown from humble beginnings as The Vallican-Winlaw Food Cooperative in 1975, into Canada's largest independent consumer owned natural foods retail cooperative.
Taking bold steps beyond the known boundaries of what coops have and can be, the Kootenay Coop has found a magical balance between for profit business, and a democratically run, consumer owned coop. The results speak for themselves with the latest bold step invovling the purchase of 3/4 of a prime downtown block in Nelson, BC and plans well underway to construct a four story mixed use development, that along with retail and condo's will also feature a greatly expanded 20,000 square foot home for the coop.
Joining us on the podcast today are Deirdrie Lang and Jocelyn Carver of the Kootenay Coop.

Cambrian: Opinion
Elephant seals shed their skin quickly at rookery
The seals look like something terrible is happening to them. Their skin is peeling off! Talk about splotchy skin. But for northern elephant seals, it's the normal, annual molt.
The adult females are on the beach in April and May, accompanied by juvenile seals of both sexes.
Elephant seals, like only one other seal (the Hawaiian monk seal) molt their skin annually in a few short weeks. All other seals molt, but most do so gradually, so it isn't as noticeable.
A new skin layer forms beneath the old skin. Blood supply to the old skin ceases and the old skin peels off in pieces. Scraps of it skitter across the beach. Friends of the Elephant Seals docents have samples of it to show visitors. Children enjoy handling it. Adults seem to be more dubious, extending a cautious finger for a touch.
The adult males are gone, and this year's weaners have left on their first migration. The beach is full of seals, but the drama of the breeding season has passed. There are actually more seals on the beach in May than during the breeding season.
The seals stop eating when they are on the beach at the rookery, fasting for that four to six weeks it takes for them to complete their molt.
Females gain weight
When the females were last on the beach, at the end of lactation in February, they were thin. They'd converted their blubber to milk to nourish their pups. They've spent the past two months eating and gaining weight.
Now, while they are molting, other invisible, but significant, changes are happening beneath the skin. Before returning to the ocean and leaving her weaned pup on the beach in February, each seal mated to conceive a pup for next season. That fertilized egg divided a few times, then stopped developing. The tiny embryo continued to float free in the uterus, dormant.
The mother-to-be spent the next two months or so feeding freely in her ocean home. When she returns to the beach in April to molt, her body makes the changes needed to have a pup next season.
After she's finished molting and returns to the ocean, that embryo implants in the uterine wall and begins normal development. Delaying development of the embryo gives her time to gain weight before starting the demands of the next pregnancy.
Staying at sea
Gestation is 7.5 months. When they leave the beach after molting, the expectant mothers will remain at sea until they return to give birth next January.
Delayed implantation is part of a complicated life cycle. Spending most of the year solitary in the water requires different strategies for breeding. So far as their lives are understood, males and females don't encounter each other except on the beach during breeding season. This is how the species has worked it out.
The 2015 breeding season produced about 4,900 live young-of-the-year, a 9 percent increase over 2014. Fewer females and fewer pups were actually born, but more survived, thanks to the mild winter weather.
Rookery tour
Learn more about molting at the Exploratory and Rookery Tour, Saturday, May 2, and May 9, at the Cavalier Plaza meeting room in San Simeon.
Come at 9:30 a.m. for coffee and to meet the docents. The talk starts at 10, followed by the tour. Free.

and Receive Complimentary E-Books of Previous Editions
Web 2.0 tools are being suggested for some years now for social life, communication, and work in various disciplines, especially in education (Alexander, 2006; Glogoff, 2005; Pempek, Yevdokiya, & Calvert, 2009). Some of these tools are the wiki, the blog, Facebook, Twitter, Second Life, Wiggio, etc. Among those who suggest these tools for education are researchers in various international conferences. For example, Ġorġ Mallia, Henk Eijkman, Asher Rospigliosi at the International Conference on Information Communication Technologies in Education 2010 suggested these tools for instruction, learning and student engagement. Being attendants at the conference, we were part of the discussions moderated by Ġorġ Mallia and Henk Eijkman in two workshops about the possibilities that Web 2.0 social networks and tools, especially Facebook, can afford to education. There our idea to use Facebook in mathematics education began.
