White paper: Providing the ARCHER community with adjoint modelling tools for high-performance oceanographic and cryospheric computation.
Publication arising from the work done: Goldberg, D., Narayanan, S. H. K., Hascoet, L., & Utke, J. (2016), An optimized treatment for algorithmic differentiation of an important glaciological fixed-point problem, Geoscientific Model Development Discussions, 1-24.
The study of the ocean and cryosphere is crucially dependent on computationally-intensive, large-scale numerical models that must be run on HPC systems. In the "forward" configuration, these models solve time-dependent boundary value problems and initial value problems with an enormous number of variables (e.g. temperature, salinity, and velocity at every grid cell) and a variety of complex physical parameterisations (e.g. small-scale mixing). "Adjoint" models, which can be derived from forward models, offer a unique, efficient method for calculating sensitivities (e.g. the sensitivity of the Gulf Stream to patterns of ice sheet melting), and are essential for constructing observationally-constrained estimates of the state of the ocean (for an example, see the SOSE project: http://sose.ucsd.edu/).
In recent years, adjoint methods have been used to gain unique insights into the ocean and cryosphere. However, the use of adjoint models on large-scale problems suitable for high-performance computing remains relatively limited due to poor access to efficient, cost-effective adjoint modelling tools. Although adjoint models are computationally expensive, requiring at least five times more CPU hours than their forward versions, adjoint sensitivity calculations are much more efficient than the alternative method of evaluating perturbed forward models. Furthermore, adjoint models remain the only practical means by which to construct observationally-constrained estimates of the state of the ocean (i.e. state estimates) in an internally-consistent way that also satisfies the model equations and boundary conditions. This project aimed to improve the UK's adjoint modelling skills by making adjoint methods more efficient and accessible on ARCHER.
The project brought together ARCHER specialists, a model manager at the British Antarctic Survey, and scientific programmers at Argonne National Lab and the Massachusetts Institute of Technology (MIT) in order to develop and optimise the forward and adjoint model test suites.

Achievement of objectives
This project aimed to bolster the ARCHER community's access to oceanic and cryospheric adjoint modelling by developing, optimising, and documenting a forward model test suite and an adjoint model test suite that could be used as the foundation for future numerical sensitivity experiments and state/parameter estimates, complementing the existing MITgcm verification experiments that come with the source code. While the verification suite is designed to be run quickly and on any platform as a simple code regression check, the suite developed in this project is specifically designed to test and exploit ARCHER's large-scale parallel computational environment, and focuses on adjoint applications. Since both ocean and ice models must rapidly and repeatedly solve large linear systems, part of this work involved optimising these linear solvers using an external library (PETSc) - this improves forward and adjoint computation equally.
The following objectives were achieved:
Ported four MITgcm ocean model test cases to ARCHER (two forward, two adjoint using OpenAD).
Created a build options file specifically for use on ARCHER. This new build options file has been checked into the MITgcm repository and is tested daily.
Implemented DIVA (divided adjoint; allows for restart of adjoint simulations) in OpenAD.
Developed an optimised treatment for algorithmic differentiation of an important glaciological fixed-point problem.
Summary of the Software
General circulation model (MITgcm)
The MITgcm is a flexible, open-source general circulation model that is widely used by the global scientific community (including many in the ARCHER community) to study the ocean, atmosphere, cryosphere, and climate. It has been run on numerous HPC platforms (e.g. ARCHER, HECToR, NASA Columbia, NASA Pleiades, NSF Yellowstone) in a wide variety of single-core and multi-core configurations (300-1000 core applications are common). Over 100 research articles published in 2013 involved MITgcm in some way. MITgcm is also highly modular, featuring a wide variety of "packages" that can be activated or de-activated depending on the experimental design. For instance, sea ice, biogeochemistry, and/or sub-grid scale mixing can be included if needed.
Algorithmic differentiation tools
One of the most useful features of MITgcm is its adjoint modelling capability. The main code has been written in parallel with two algorithmic differentiation (AD) tools (i.e. TAF and OpenAD) that take large, frequently-updated numerical code as input and produce "differentiated" code as output. The differentiated code can be used for sensitivity analysis, optimisation, and state estimation. It is worth noting that, as TAF and OpenAD produce compilable code, the adjoint model inherits many of the properties of the forward model, such as domain decomposition, multithreading, and choice of linear solvers. Thus, gains from optimising forward model performance will directly improve adjoint model performance as well. TAF is a well-developed commercial package that produces very efficient code but is expensive to use, while OpenAD is a newer package that is less efficient but is open-source and free to use.
Linear solvers within MITgcm
The ocean and ice-sheet codes involve the repeated solution of large-scale linear systems, accounting for between 25% and 80% of forward model computation. Since the self-adjoint property of these linear systems is exploited by the adjoint model, linear solves affect both forward and adjoint model performance in a similar fashion. Thus it is crucial to optimise their performance.
PETSc is a leading open-source software package for the efficient parallel solution of large linear systems. An MITgcm interface has been written (for the ice model only) to the PETSc library, and some investigation of preconditioner and solver suitability has been carried out. However, the investigation was far from exhaustive, and MITgcm-PETSc interfacing has not yet been tested on ARCHER. Furthermore, no such interface has been written for the ocean model, but its development is anticipated to be straightforward. Once implemented, the performance of various PETSc preconditioners and solvers in the PETSc library will be compared in the context of the test suite.

Scout's Notebook
NFL's top 10 second-year players; Washington Football Team rebrand
Published: Jul 24, 2020 at 05:02 PM
Former NFL player and scout Bucky Brooks knows the ins and outs of this league, providing keen insight in his notebook. The topics of this edition include:
-- Can the Rams reinvigorate their ground attack by copying the 49ers' approach?
-- How COVID-19 precautions could impact home-field advantage.
-- Why the Washington franchise's decision on a temporary name was a winner.
But first, a look at 10 second-year players on the path to stardom ...
The release of NFL Network's "Top 100 players of 2020" (Sunday-Tuesday, 8-11 p.m. ET; Top 10 on Wednesday, 8-10 p.m. ET) should be must-see TV for executives, coaches and scouts around the league. The peer-to-peer evaluations not only provide players with an opportunity to share their perspective on what separates the elites from the rest of the pack, but this annual series also gives observers an opportunity to discover which traits matter when it comes to evaluating talent.
In the NFL, scouts are taught to wait for three years before determining if a new player can make a living in this league or not. Mitigating circumstances (scheme, coaching, injuries, etc.) could prevent a blue-chip prospect from realizing his potential early in his career, so evaluators are encouraged to give him enough time to develop into the player that they envisioned when scouting him as a collegian.
To be honest, though, as a former player, I disagree with the extended timeline -- particularly when it comes to blue-chippers. The elites display five-star traits early and it's easy to envision them emerging as game-changers. That's what I witnessed while playing with Tony Gonzalez and Charles Woodson during their respective rookie seasons. Despite some rough patches, it was apparent that each player had all-star potential -- the elite traits stood out whenever you watched them in drills.
During my time as a scout with the Carolina Panthers, it didn't take long to notice a pair of youngsters: Julius Peppers and Steve Smith. Each player displayed a penchant for delivering game-changing plays. Peppers earned Defensive Rookie of the Year honors, while Smith snagged a Pro Bowl berth as an electric returner in Year 1.
With those players setting the ceiling for my expectation of young players, I decided to study the All-22 Coaches Film from the 2019 season to see which 2019 NFL Draft products could be ready to join the ranks of the elite in Year 2. Given some time to take notes on each of the notable contributors from the class, here are my top 10 second-year players:
Arizona Cardinals · QB
The Offensive Rookie of the Year could be the new prototype at the position, as an A+ pocket passer with electric running skills. Murray dazzled opponents in 2019 with a unique playing style that kept defensive coordinators up at night crafting schemes to contain a playmaker who would eclipse 3,500 passing yards and 500 rushing yards as a rookie. With an upgraded supporting cast around him in 2020, the 5-foot-10 dynamo could help the Cardinals make a run at the NFC West title and emerge as a dark-horse MVP candidate.
San Francisco 49ers · DE
The 49ers' Energizer Bunny is a game-wrecker off the edge. Bosa overwhelms blockers with his relentless energy, effort and violent hands on the way to the quarterback. The scrappy Ohio State product also displays outstanding strength, power and pop stacking blockers at the line while tracking down runners. As the tempo setter on a talented 49ers front, the reigning Defensive Rookie of the Year could vie for Defensive Player of the Year honors in Year 2.
Jacksonville Jaguars · DE
Despite logging just four starts, Allen quietly led rookies in sacks with 10.5. His efficiency as a situational pass rusher bodes well for a defense that needs the second-year pro to become a consistent force off the edge opposite (or in place of) Yannick Ngakoue. With the disgruntled Ngakoue intent on forcing his way out of Jacksonville, Allen's rise as a premier playmaker off the edge could help the defense survive the loss of a Pro Bowl-caliber talent on the other side.
Tennessee Titans · WR
Brown entered the league viewed as a possession receiver, but emerged as the Titans' biggest playmaker in the passing game. He registered a 1,051-yard season on just 52 catches (20.2 yards per catch), thanks to a whopping eight grabs of 40-plus yards, which was tied for the league lead with Mike Williams and Stefon Diggs. Brown's physicality, toughness and RAC (run after catch) ability set him apart from his peers and thrust him into the conversation as an emerging elite player.
Devin Bush
Pittsburgh Steelers · LB
The Steelers' 'backer gobbles up runners like Pac-Man devours dots. As a rookie, Bush racked up 89 tackles as a sideline-to-sideline playmaker, but he made his biggest contributions as a turnover machine. The Michigan product produced six takeaways (two interceptions and four fumble recoveries, including an astute scoop-and-score) while displaying outstanding instincts, ball skills and aggressiveness. Bush's immediate impact helped fuel the Steelers' top-five defense and established No. 55 as a rising star at linebacker.
New Orleans Saints · C
The No. 48 overall pick from last year's draft has entered the discussion as one of the best pivots in the game following an impressive rookie campaign. McCoy is a rock-solid blocker with the capacity to maul defenders in the running game and stonewall interior rushers in pass protection. With a polished game and a high IQ, the Saints center could become the gold standard at the position for this decade.
Las Vegas Raiders · RB
Jon Gruden's desire to pound the rock could make Jacobs a full-blown star in Year 2. The hard-nosed runner showed immense promise as a first-year starter on the way to cracking the 1,000-yard mark (1,150 rushing yards, to be exact) in 13 games. He flashes make-you-miss ability in the hole with a touch of explosive power and pop that makes defenders pause before approaching No. 28. Considering how intent the Raiders are on running the ball to alleviate some of the pressure on Derek Carr, Jacobs could make a run at the rushing crown during his sophomore campaign.
Washington Football Team · WR
The 6-foot, 210-pound speedster is already one of the scariest big-play threats in the NFL. As an explosive athlete with excellent stop-start quickness, McLaurin has the capacity to blow past defenders on vertical routes while also weaving through traffic as a RAC specialist. With the second-year pro also displaying polished route-running skills, Washington's WR1 has the potential to become a top-10 playmaker at the position.
Darnell Savage
Green Bay Packers · S
The versatile safety could become a household name worthy of all-star recognition by the end of his second season. Savage is a rare find as a hard-hitting enforcer with superb ball skills and instincts. In 14 games last season, he snagged two interceptions and forced a pair of fumbles, displaying outstanding range, instincts and anticipation as a crafty deep-middle defender.
Jeffery Simmons
Tennessee Titans · DL
Despite playing just nine regular-season games after recovering from a pre-draft knee injury, Simmons quickly made his mark as a disruptive interior defender with A+ run-stopping ability and pass-rush skills. The rugged defensive lineman finished with a pair of sacks, four tackles for loss and two QB hits, but those numbers don't properly showcase his impact. Simmons displayed game-changing flashes as an athletic penetrator with an array of dance moves.
RAMS' RUN GAME: Will copying 49ers pay off?
"Imitation is the sincerest form of flattery that mediocrity can pay to greatness."
I don't know if Sean McVay is a literary scholar, but the Los Angeles Rams' head coach appears to be taking a page from Oscar Wilde after watching his team's running game fall apart in 2019. With an eye pointed toward the defending NFC champion San Francisco 49ers, the offensive wizard dismissed Todd Gurley in favor of rebuilding the team's scattershot ground attack behind a committee approach.
"I think it'll just naturally work itself out. I think if you look at that success San Fran had last year with that running back-by-committee approach," McVay recently said, via Cameron DaSilva of The Rams Wire. "What I thought Kyle (Shanahan) and their players did a great job of is, 'Hey, we're going to have an open-mind approach, we're going to be committed to trying to have some balance and then we'll go with the hot hand or whoever really expresses himself as deserving of the carries.' "
Last season, the Rams were essentially a two-man operation at running back with Gurley and Malcolm Brown sharing duties in the backfield. The 2017 Offensive Player of the Year was slotted in the No. 1 role, but he ceded carries to his backup as part of a plan to reduce his workload and try to keep him healthy. The results were ... not great. The 2019 Rams ranked 26th in rushing yards per game and tied for 27th in yards per rush after finishing in the top five in both categories back in 2018, when Gurley carried the bulk of the load. Sure, C.J. Anderson stepped in and provided a boost for the offense for a few games down the stretch in '18 while Gurley nursed an injury, but the running game was largely anchored by a one-man show for the first two years of McVay's tenure.
That said, the RBBC model has worked in the NFL, particularly for teams utilizing the Shanahan system. The zone-based scheme has turned a number of late-round draftees and undrafted free agents into stars. The combination of an "elephants on parade" blocking scheme and a decisive one-cut runner has yielded huge results for teams employing the system. McVay, who spent four seasons with the Shanahans (Mike and Kyle) in Washington, employs the same kind of zone-blocking system in the ground game -- an approach that allowed Gurley to earn back-to-back first-team All-Pro honors in 2017 and '18.
Given the success of the 49ers' rushing attack, it is not surprising the RBBC approach is trending in the NFL. Despite witnessing his team's previous success with a workhorse leading the way, McVay believes a multi-back system could help the Rams re-emerge as a force on the ground.
"We feel good. We've got three guys really on our roster that have played football when you look at Darrell Henderson, John Kelly is another guy, Malcolm Brown has consistently produced in that No. 2 role behind Todd," he said. "And then Cam Akers is a guy that we're excited about. So we've got four backs that we feel like are all NFL-legitimate, starting-caliber backs and not feeling like you've got to force carries or touches to any of them. Just open mind and see how these guys do."
McVay might tout the talent and potential of Henderson and Kelly, but the workload could ultimately be split between Brown and Akers. Brown, a sixth-year veteran, will get the first crack at carries, based on his experience and flashes as the team's RB2 in prior seasons. Although Brown has mustered just 769 rush yards in 54 career games, he is coming off a five-touchdown season in which he displayed short-area power and pop. He hasn't posted a 100-yard game during his career, but he has shown potential as a short-yardage/goal-line/four-minute-offense specialist.
Akers, the team's top pick in this year's draft at No. 52 overall, could eventually emerge as the lead back in the rotation. The Florida State product is a dynamic runner with a versatile style that enables him to thrive as a one-cut runner within a disciplined zone scheme or as a shake-and-bake playmaker in the open field. He is an excellent receiver out of the backfield with a knack for turning short passes into big gains, particularly on screens. Akers not only has the most complete game of any runner in the rotation, but he is a natural fit in the team's scheme as a multi-faceted playmaker -- which is exactly what Gurley has been at his best.
At the end of the day, McVay's copycat plan could help Los Angeles close ground on division rivals and re-emerge as a threat in the NFC. Or it could just be the sincerest form of flattery that mediocrity can pay to greatness.
COVID-19: Impact on home-field advantage
The COVID-19 pandemic has prompted some NFL teams to announce they will limit the number of fans allowed to attend games, and in the case of the Giants and Jets, not allow any fans in. These plans are being made with safety and health in mind, as they should be, but in these highly unusual times, I do believe having a smaller crowd -- or no crowd at all -- will impact the game and alter how some of the NFL's heavyweights compete this season.
That sentiment might lead to quizzical looks from some folks, but home-field advantage matters in the NFL. Take a look at the top home records since 2015, per NFL Research:
New England Patriots: 33-7
Kansas City Chiefs: 29-10*
Minnesota Vikings: 29-11
Pittsburgh Steelers: 28-12
Green Bay Packers: 27-12-1
Baltimore Ravens: 27-13
New Orleans Saints: 27-13
*Kansas City played a neutral-site game in London back in 2015 where they were the designated home team, but that wasn't counted here.
It's not a coincidence that the last two Super Bowl winners are at the top of the list. Great teams dominate their opponents at home, using those games to help them earn pole position in a playoff run. That's why we should pay close attention to the correlation between those impressive records and the 24 combined playoff berths (and three Super Bowl wins) among those squads in that span.
Stacking wins at home helps contenders inch closer to the magic number (10) that has traditionally resulted in a playoff berth. Part of their success can be attributed to defenses taking advantage of the noise and energy from the home crowd. Pass rushers, in particular, exploit the crowd noise to "jump the snap" (anticipate the snap count) to blow past offensive tackles on speed rushes. Moreover, the NFL's premier sack artists have always punished quarterbacks when they're able to take advantage of late-reacting offensive tackles who are affected by the crowd noise.
During my playing days in the 1990s, I watched three of my Pro Football Hall of Fame teammates (Reggie White, Bruce Smith and Derrick Thomas) abuse opposing offensive tackles at home. Each pass rusher would utilize initial quickness and snap-count anticipation to get a head start at the line. Thomas, in particular, would capitalize on the raucous environment at Arrowhead Stadium. He not only fed off the energy of the crowd, but he overwhelmed hesitant pass protectors with his exceptional first-step quickness and anticipation of the snap. No. 58's get-off, burst and acceleration made him an unstoppable force off the edge on obvious passing downs at home.
I was on the field during the 1998 season opener against the Raiders when he sacked Jeff George six times -- one of which resulted in a safety -- and forced a fumble. It was the most dominant individual defensive performance that I've witnessed during my 20-plus years in and around the league. It also illustrated how an elite pass rusher can take over a game when the home crowd is whipped into a frenzy. My belief in this notion was only strengthened after studying the largest home-to-road sack differentials among the 34 members of the 100-plus sacks club:
Derrick Thomas, Chiefs: +42.5
Dwight Freeney, Colts and Cardinals: +31.5
William Fuller, Oilers: +25.5
Jared Allen, Chiefs and Vikings: +23
Robert Mathis, Colts: +22
It's interesting to note that three of those five players (Freeney, Fuller and Mathis) spent the bulk of their careers with teams that played their homes games indoors. Allen and Thomas played in front of what's been dubbed the loudest crowd in the NFL at Arrowhead Stadium (according to Guinness World Records), and Allen also spent half his career with the Vikings, who played their home games in a dome.
When I take another glance at the aforementioned teams with the best home records since 2015, I don't believe it's a coincidence that each squad currently features, or recently featured, a five-star pass rusher in the starting lineup. OK, the Patriots might be the exception, but keep in mind that they place a premium on coverage over pass rush with their defensive approach.
That said, the Vikings could be the team that's most impacted by a small or nonexistent home crowd. Mike Zimmer's squad has 34 more sacks at home than on the road since 2015 (125 sacks at home; 91 sacks on the road), with Danielle Hunter and others feasting on opponents overwhelmed by the raucous Minnesota crowd.
Without the usual noise and energy to tip the scales in their favor, particularly with the defense on the field, the Vikings would lose one of the biggest advantages in the league. The Steelers, Packers and Saints would also miss out on the favorable conditions that routinely help lead to Ws.
As such, playing with small crowds or no fans in the stands could open up the playoff field this year and potentially play a significant role in the postseason with only one team in each conference receiving a bye in the new playoff format.
WASHINGTON REBRAND: Applause for temp name
I LOVE the Washington NFL franchise's decision to temporarily name its club the Washington Football Team. While a quick scan on social media shows many folks disagree with me on this, I believe the name and new uniforms are bold in a unique way.
I know the decision makers within the organization are doing their due diligence to come up with a more permanent solution, but going with this name is ideal for the moment. It provides an opportunity for unity after so many years of division. By using the moniker "Washington Football Team," it allows head coach Ron Rivera to stand in front of his players and promote team over self in every action.
At the same time, the franchise needs its supporters to embrace an old-school style (leaning on the running game and defense) that always has a place in the NFL. With a defense that should be led by a front line that features five former first-round picks in the rotation, including Chase Young (the No. 2 overall selection in this year's draft), the Washington Football Team has an opportunity to play throwback football in the NFC East.
Offensively, the team has an all-time great at tailback (Adrian Peterson) to spark an offense that should embrace a ground-and-pound approach that enables it to keep the game close if the defense plays up to expectations. The ball-control philosophy might not endear the Washington Football Team to fans of razzle-dazzle football, but it's a time-tested formula that has worked since the beginning of the league and continues to produce solid results in today's game (SEE: Baltimore, Tennessee, San Francisco, and New England, among others).
While I'm not ready to proclaim the Washington Football Team the next great squad to take the NFC by storm, I believe it's following in the footsteps of the greatest achievers in life by boldly featuring a single name (Washington) as its brand. Considering the success of Prince, Sade, Madonna, Seal, Jay-Z and others, the franchise's bodacious approach reflects an arrogance that often precedes excellence.
OK, I know that might be a reach, but as a fan of Premier League soccer, I believe the decision also reveals the team's desire to begin a new (and hopefully more successful) era by prominently featuring the city it calls home in its temporary name. There's nothing like representing your city on the pitch and in the stands. The team's approach enables the fan base to embrace being different in a copycat league.
I remember when the 2001 New England Patriots ran out of the tunnel as a team prior to Super Bowl XXXVI before shocking the world by knocking off the St. Louis Rams. The approach was radically different from the norm at the time (starters were announced individually), but the decision to come out together provided the football world with a glimpse of the culture that existed within the squad. Six Super Bowl wins later, the Patriots are viewed as the gold standard in the league with a team approach that the football world appreciates and respects.
If the Washington Football Team utilizes this temporary name to really establish a team-first culture under Rivera, the jokes about the moniker could subside quickly as a contender re-emerges in D.C.

The number of foreign tourists visiting the Netherlands grew by 5.5 percent to more than 15.8 million last year, according to a report by Statistics Netherlands and the World Tourism Organization (UNWTO). The tourism growth is stronger in the Netherlands than in most other European countries.
World wide tourism grew by an average of 4.8 percent per year since 2008. Last year the number of tourists worldwide grew by 3.9 percent to more than 1.2 billion. Asia and Oceania and Africa are particularly benefiting from the growth, while Europe's growth was more variable.
In 2016 the number of tourists in all of Europe grew by an average of 2.4 percent. For the 28 European Union member states, the growth averaged at 4.6 percent. Northern Europe saw the biggest growth at 6.1 percent, followed by Central and Eastern Europe with 3.7 percent. In the Western European region, tourism did not increase last year.
The Netherlands showed a positive peak in tourism in Western Europe. The number of tourists in the Netherlands increased by 5.5 percent. Tourism in the Netherlands also grew faster than other EU countries and the world in 2014 and 2015, according to the institutions. At 76 percent the bulk of foreign tourists in the Netherlands come from within Europe.. Non-European tourists visiting our country mainly come from the Americas, 9.2 percent.
Tourism in the Netherlands and globally continues its growth in 2017. In the first eight months of this year, global tourism grew by 6.6 percent compared to the same period in 2016. In the Netherlands, tourism grew by 13.1 percent to 12.4 million foreign guests in the same period.
Tourism is the third largest export product in the world, after fuel and chemical products.

Q: Oracle DB lock table use Recently I had a task, according to which, I needed to have a specific lock functionality. The specific was due to:

*

*Transaction that was updating
  table was distributed, so I had no
  controll over it,

*During the day
  thousands non blocking transactions
  must be supported simultaniously,
  lets call them 'general' operations,

*Each 'general' operation updated rows on specific 'branch' ("LDN","NY","LA" ...),

*Once a day there is a 'master'
  operation for each branch, which happen spanteniously, on different branches,

*

*During 'master' operation no
  'general' operations on that branch can happen.

*When 'master' operation start it
  must wait for current 'general'
  operation on the provided branch completion,
  which were in the system before 'master' operation arrived.

*Durring 'master' processing on a specific branch, all other branches can be
  updated.

In order to archive this, I created Oracle DB specific table
create table BRANCH_LOCK(
    BRANCH VARCHAR2(10),
    FLAG   VARCHAR2(1),
    CONSTRAINT "PK_BRANCH_LOCK" PRIMARY KEY ("BRANCH")
)

The following functionality for different operations was supported:
For 'general' operations:

1. In the same XA transaction each operation locks BRANCH_LOCK table
   in SHARE mode,
2. After locking it checks FLAG, on updated branch,
  1. If flag is 'Y', that means that currently 'master'
      operation is in progess, so  Exception is thrown,
     and no further processing is done;
  2. If flag is 'N' than everything is OK, and general processing is done;

For 'master' operation:

*

*When 'master' operation comes I start separate transaction which:

*

*Lock BRANCH_LOCK table in EXCLUSIVE mode, which transaction can not acquire while          there is SHARE mode LOCK on this table in  a different transaction (This way, I guarantee that 'master' operation would start after all current 'general' operation finish, although it waits for transactions on all branches
  to finish, not only specified one),

*Sets flag for the branch to 'Y'
  (This way, I guarantee that there would be no 'general' transactions while 'master'
  operation processing),

*In incoming transaction I change a Flag in the table to 'N', so after
  it commits BRANCH_LOG table will have
  appropriate value in FLAG column, and system would
  be able to process 'general'
  operations again.

This has not gone in production yet, So I wonder is there a better solution for this,
and are there any more drawbacks besides described one?
Some updates, which I did not mention:

*

*'Master' operation works on results of 'general' operations, So it is vital, that no 'general' operation get lost, durring the 'master' processing, so this why current 'general' operation must finish, before master operation start processing.

*Multiple 'general' operations on the same branch happen every second, arround 3'000 operations per second,

*Only one 'master' operation for the branch can happen, multiple 'master' operations on different branches can be processed at the same time.

A: Anton,
why exactly do you need to manually lock the table[s]? Normally there is no need to do such. When the master operation you describe starts, it get's a read consistent view of the data that is committed at the start of that master transaction. The general transactions can continue to work and the master transaction you describe will not see the changes, until it starts a new transaction.

A: Rather than build my own lock table, I think I'd try to use Oracle's locking package DBMS_LOCK.
It's more efficient than using DML to do locks, and is what Oracle uses internally to perform enqueue locking.

A: What are the table volumes.
I'd consider having the master operation start like
CREATE OR REPLACE PROCEDURE do_master (in_branch IN VARCHAR2) IS
BEGIN
  SELECT ...
  BULK COLLECT INTO
  FROM ...
  WHERE branch = in_branch
  FOR UPDATE OF branch;
  ...
END do_master;

That would use standard Oracle locking to ensure that the do_master waits until outstanding general transactions locking those branches complete, then the locks are taken by do_master stopping any other general updates until it commits. Then those general updates resume.
But if the volumes are big, then that SELECT...FOR UPDATE could be very large. That's when I'd consider a DBMS_LOCK solution.

Napoléon Antoine Eugène Léon de Saint-Lubin (* 5. Juli 1805 in Turin; † 13. Februar 1850 in Berlin) war ein Geiger und Komponist italienischer Herkunft.

Leben
Saint-Lubin wurde als Sohn eines französischen Sprachlehrers in Turin geboren, kam aber schon in seinem vierten Lebensjahr nach Hamburg, wo er ersten Violinunterricht sowie Unterricht auf der Harfe erhielt. Von 1814 bis 1817 erteilte ihm Giovanni Battista Polledro (1781–1853), ein Schüler Pugnanis, in Dresden Violinunterricht.
1817 trat er bereits in Berlin und Dresden auf und ging 1818 nach Frankfurt am Main, wo er Schüler von Louis Spohr wurde. 1820 ließ er sich schließlich in Wien nieder und fand dort große Anerkennung.

Beethoven widmete Saint-Lubin ein kleines Solo-Stück, eine Kadenz, nachdem Saint-Lubin bei der Wiedereröffnung des Josephstädter Theaters am 3. Oktober 1822 ein Violinsolo von Beethoven gespielt hatte. Das Autograph war später im Besitz der Österreichischen Nationalbibliothek unter der Signatur Sm 3154, ist aber im Zweiten Weltkrieg verloren gegangen. Es trägt die Werknummer Hess 296.

1823 wurde Saint-Lubin Konzertmeister am Josephstädter Theater, 1824 Kapellmeister. Später lebte er für längere Zeit als Musiklehrer in Ungarn, u. a. ein Jahr lang auf den Gütern des Grafen L. Festetics. Hier suchte er sich nach dem Vorbild Paganinis als Virtuose zu vervollkommnen. 1830 erhielt er eine Berufung als Konzertmeister an das Königsstädtische Theater in Berlin. In dieser Stellung blieb er bis 1847. In seinem Haus veranstaltete er Konzerte und Quartettversammlungen, in denen sich die berühmtesten Virtuosen, wie Spohr, Liszt, Servais und Mendelssohn hören ließen. Neben virtuosen Violinstücken schrieb Saint-Lubin auch Lieder, die von Robert Schumann anerkennend erwähnt wurden, Violinduos, Klaviertrios, Streichquartette, Streichquintette sowie ein Oktett für Bläser und Streicher.

Er starb nach jahrelanger Kränklichkeit am 13. Februar 1850 in Berlin.

A great set of GCSEs and post 16 qualifications is good, but students need much more if they are to really succeed and thrive both in life and the workplace. The job market is changing rapidly: the average student leaving school this year will have 14 different jobs by the time they are 38. They need to develop transferable skills and have the tenacity and flexibility to cope with change. They also need wisdom to avoid pitfalls and make positive life choices.
My READY programme provides the skills, knowledge and wisdom to cope with the challenges of life as well as thrive in the changing workplace.

"Blame" is a Window into the World of Human Trafficking
By Dylan Deprey
Pastor Martha Austin is the writer, director and producer of the play, "Blame." (Photo by Dylan Deprey)
A girl in her early twenties sits on the couch. Her dad comes home from work drunk, and is ready to sexually abuse her for the second night in a row. The intensity builds as the walls tremor. Her mother arrives and in her hand she wields a pistol.
The father sits in the crosshairs as she aims the gun at the man who gave her HIV. The gun blasts as screams grasp at the audience's heartstrings. The young black female is now responsible to raise her sister, a girl just few years younger then her.
She is a young adult who is insecure and unaware of the dangers of those who could really hurt her. After being guided by the wrong people, her ignorance for her own identity leads her to leave with a charming man at a club. This is the same man who gets her hooked on heroin and pushes her to work the streets.
For the past couple of years Milwaukee has held the infamous title of one of the biggest human and sex trafficking hubs in the country. It is an industry diluted by the forced silence of young girls lured from broken homes and promised unimaginable hope. It is an industry that has few repercussions for the "Johns" who come from all walks of life.
The Destiny Productions play, "Blame," is a real-life window into the world of sexual, physical and mental abuse that transpires everyday to the women forced to work the streets of Milwaukee.
Pastor Martha Austin is the CEO of Destiny Productions. She is also the writer, director and producer of "Blame." She previewed the show for fellow pastors, elected officials and family at the In Tandem Theater, July 31.

The preview was just a taste of the entire play, which is set to take the stage at the Marcus Performing Arts Center on September 30th and run until October 1st.
Austin said that the play touches on the underworld of human trafficking and the suicidal levels of low self-esteem. It also intertwines the desperation of drug addiction and the spirit of murder.
"Doesn't this sound like something we're all accustomed to now," Austin said.
The cast is primarily made up of local Milwaukee actors and actresses. Jeremy Flowers plays an ex-pimp turned pastor who tries to reason with some of the current pimps on the street.
Flowers may have a different name in the play but he actually is replaying his own life. Flowers said he turned his life around and left the sex trafficking industry after finding God.
"I just want to present a real sense of reality in the play," Flowers said. "It's emotional for me because I've played the other role."
Elected officials were asked to acknowledge some of the issues presented in "Blame." Sen. Lena Taylor said that she saw a piece of her own life in the play. She related with the main character having to take care of her younger sister when she was a "sister-mom" to her younger brother.
David Crowley, a Candidate for Wisconsin State Assembly, 17th District, said the play reminded him of where he grew up and the drug abuse that plagues the streets of Milwaukee. He said that when he was a child he would get home from school, drop his backpack off and stay out until the lights came on because his house was the crack house.
"What I have realized is that this doesn't' necessarily just talk about what's going on in our community because we see this everyday, but this is also what our leaders see," Crowley said.
"If we are talking about solving this, we need to come together as people and that is the only way we are going to solve this," Crowley said.

In just the first two pages, Hogarth establishes that this is another world (with three moons), that Angharad can fly (her wings were injured in the battle for Glendallia; also, "A warm breeze presages spring and sweeps my fine hair off my shoulders, tickling my wings." – Angharad wears a backless blouse with breeches), that the creatures of this world can interbreed and do not look like each other, and that the royal court is REALLY anxious for the politically inexperienced Angharad to take command of the large province of Shraeven (until recently an independent kingdom) as soon as possible. She is promised all the additional troops she wants, a new support staff, an almost unlimited expense account – but she, personally, has to be the new Governor. Angharad suspects that the "newly pacified province" is in fact a hellhole, and that she is expected to fail – but who wants her, personally, to be a scapegoat?
Of important added interest, there are constant references to this planet's unique biology.
And all the above is just in the first chapter! This all results in a novel of political intrigue in which the Furry element is especially important. There is no human vs. Furry conflict; everyone is a Furry of one kind or another, with many more blends than Earth has species. It is almost immediately evident that in this context, "man" means anyone who is sentient.
This first half of a novel has been revised from a collaborative serialization that Hogarth published on LiveJournal from October 2003–June 2009.

I gotta say it is extremely difficult to tweak vocabulary for anthropomorphic fiction so that it doesn't overlap with terms that are tailored toward humans or one's own experiences in this universe.
For example the phrase "He was a good man" came up when I was writing and it's a common phrase but since the person who died wasn't a "man" as in male human I went bzzzt try again. After a little that one was easily tweaked to "He was a good spirit".
More challenging was the story was on a different planet and I had to describe a sun rise... where's the challenge in that? Well, it's like a game of taboo... I can't use the word "Sun" because the "sun" isn't a word used to describe the star in the center of every universe, it is used as a specific name for a particular star we are most familiar with. So yes I could use the word sun, but what are the odds that an alien culture would come up with the same name for their star as we ours? So I simply called it "the fire in the sky" and used other metaphors to avoid giving it a name, which was a bit more difficult.
Sci-fi and furry writing definitely provides a challenge to ones vocabulary and understanding of societal definitions and etymology if one tends to over-think things.
In my work (most notably in By Sword and Star), I often use "man" or "woman" to simply indicate male or female character, instead of assuming that the terms automatically mean "human." I don't see a problem with it, especially when there aren't any humans in a story's world, but apparently it trips up some readers who take things very literally. *shrug* I'm all for using appropriate idioms and such (I remember critiquing a story where a zoomorphic fox talked about 'learning the ropes,' which didn't make much sense from a real-life fox's perspective), but at some point you do get into the calling-a-rabbit-a-smeerp type problem, and it becomes overblown and distracts from the story you're trying to tell.

Q: How can we get the Image Path or URL of createImageView in Titanium Developer using Javascript click addeventlistener? I have an ImageView, on click of the ImageView I would like to get the Image Path (image or url) inside the addEventListener, how can we achieve this. Or simply my question is how can we get the information of properties of ImageView when we click on the Image using click eventlistener in Titanium Developer using javascript.
img = Ti.UI.createImageView({
image: 'http://www.xyz.com/v2/media/Images/Venue/' + photoName + '?' + rand,

clipsToBounds: true

});

img.addEventListener('click', function(e)

          {

    });

Can we access imageview information from 'e' of 'click' event of the addEventListener ?

A: yes you can do. The way @Muhammad Zeeshan has given is also works but only when your img object is visible or global.
If you want to access it using "e" object. You can access it like this,
img.addEventListener('click', function(e){
  var path = e.source.image;
});

you can access all the property of all ui controls in their event listeners using e.source.*

A: Yes you can,
Just do this.
img.addEventListener('click', function(e){
  var path = img.image;

});


Image: Precinct 2 Montgomery County Commissioner Charlie Riley lies awake every night fearing a barge crash into the State Highway 242 at Interstate 45 flyovers, in the event the Montgomery County government were recklessly to remove the flyover tolls. This photograph depicts Riley's worst nightmare scenario.
Conroe, April 10 – Precinct 2 Montgomery County Commissioner Charlie Riley made what was easily the most stupid comment ever made in the history of the Montgomery County Commissioners Court when he expressed a concern that a barge might hit the flyovers at the intersection of State Highway 242 with Interstate 45 to cause an extraordinary high maintenance expense to Montgomery County's government, in the event that the Texas Department of Transportation did not assume the cost of the flyover maintenance.
The discussion arose during the Commissioners Court's consideration of County Judge Mark Keough's proposal to remove the flyover tolls.
The taxpayers of Montgomery County finished paying the bond debt for the flyovers in January, 2018. In year since the taxpayers paid that bond debt through tolls, Riley and other members of the Commissioners Court failed to determine whether the Texas Department of Transportation (TxDOT) would take over the SH 242 flyover maintenance, if the County government chose to end the tolling of the flyovers. Now, we sit over a year later, and Riley and his cohorts have failed to take any action.
Riley desperately wants to continue the tolls forever. In previous Commissioners Court discussions, Riley has made clear that he wants the "revenue" from tolls to pay for other road projects for Montgomery County forever. Therefore, Riley, who had the primary responsibility to determine whether TxDOT would take over the maintenance expense for the flyovers which connect a state highway to a federal highway, seems to have failed purposefully to determine who would assume the maintenance expenses, if Montgomery County ended the flyover tolls.
The flyovers are approximately one hundred (100) feet in the air. Barge traffic along Interstate 45 would seem likely to be rare.
Riley's latest argument to continue to toll the SH 242 flyovers, a tax which Riley obviously enjoys collecting, seems to be his concern about barge traffic at the intersection of Interstate 45 and State Highway 242.
Undoubtedly, the continuation of the SH 242 flyover tolls would also defray the cost of maintenance, if a truck carrying jackalopes were to knock down the flyover pylons after swerving to avoid hitting a sasquatch and a bag of snipe.

Marriage certificate issued by J. H. Kidder for Miles A. Barnes of Fort Fairfield and Lizzie C. Alexander of Blaine, on the occasion of their wedding of 2 Nov 1880 at Blaine, Maine. Fort Fairfield and Blaine are towns in Aroostook County, near the border with New Brunswick, Canada.
Interestingly, an online source mentioned that Miles' grandfather was a Loyalist who moved to New Brunswick, Canada, from New York. At some point subsequent, probably in 1842 with the ratification of the Webster Ashburton Treaty, the border was changed so that his farm, or at least his house, was from then on located in the United States.
Miles A. Barnes was born in 1949, the son of Joseph and Sarah (Kinney) Barnes. I've found some conflicting information on Joseph and Sarah and will continue researching them.
Lizzie C. Alexander [actually Elizabeth Chloe or Chloe Elizabeth], the daughter of Joseph and Elizabeth (Shirley) Alexander, was born in 1857 in Fredericton, New Brunswick, Canada, and died in 1909.
Miles and Lizzie had at least one son and one daughter.
I hope you find this interesting! If you have any insights into the Barnes or Alexander families of New Brunswick and Aroostook County, Maine, please contact me.

There is a big debate in the fitness and workout world about the effectiveness of listening to music and working out at the same time. While you may be firmly on one side or the other of the issue, it's important to consider and weigh carefully the arguments of the other side before you proceed.
In favor of music while working out, some point out that having music keeps them focused and shuts out distractions. An hour-long workout session can go by seemingly fast, and they do not encounter any boredom during the workout. The opposing side swears by no music at all. Rather, they say music can be distracting and lead to less intense workouts.
That said, whether you use music during the workout or only listen to it beforehand, here are some motivating tracks that can get you in the mindset for a powerful workout.
Rock music is a natural fit for workouts. With a heavy, insistent, beat and crunchy power chords, this genre can help you get into the groove for a serious workout.
One of the top tracks that have a motivating message for facing the challenge of working out is Tom Petty's "I Won't Back Down." Petty's defiant, determined vocal and the crescendo of hard rock guitars make a perfect backdrop to any hard weightlifting.
Another inspirational track in this genre is Survivor's " Eye Of The Tiger." Made famous in the Rocky Balboa movie series, this was a track that the movie's hero, played by Sylvester Stallone, would work out to. It might just inspire you to aim higher with your workouts.
<p>Country might be a more laid back genre of music than rock- but that does not mean that it can’t motivate you to withstand the hardships of the gym. In fact, the mellow tones of country can make it the ideal background. It's music that lets you focus on your bench press or squats.
“My Kinda Party” by Jason Aldean is one of those country songs that can lighten the mood of your workouts. There is no reason to view working out as a chore. You can let Aldean’s Southern twang and happy lyrics about partying in Georgia set the tone. The only difference is, you will be partying it up in the workout.
Taylor Swift’s “Mean” expresses the struggles and aspirations of small-town country with big dreams. The lyrics, about staring down a formidable adversary, are a pointed metaphor that applies well to lifting weights or running the treadmill.
Hip-hop is another of the genres of music that have seen a rise in popularity. It's about tales of struggle and working to beat the odds, along with memorable hooks.
Daddy Yankee’s “Gasolina” blends infectious crooning with a highly active beat to make one of the genre’s great workout songs. Though you might not understand the Spanish in this track, you will be half tempted to dance along during your workout. Don’t, just pump the weights harder instead.
Another hip-hop track that can spur you to workout better than ever before is the classic “U Can’t Touch This” by MC Hammer. Hammer was a great dancer in his heyday and this song is as inspiring for the dance floor as it is for the gym.
If music is not your thing, you might prefer to workout with an audiobook playing in the background instead. Audiobooks can be a great tool for educating yourself while doing other important things, like working out.
You can find audiobooks to purchase on platforms like Amazon’s Audible and Apple’s iTunes. Some good audiobooks to inspire your workouts include Tom Brady’s “ The TB12 Method” and Kobe Bryant’s “ The Mamba Mentality: How I Play.” These are books by athletes who have competed at the pinnacle of sports and have certainly paid their dues in the gym. Hearing it straight from the greats will motivate you to give every workout your best.

Kealoha mailbox trial witness list: Who's on, who's missing
by: Gina Mangieri
Posted: May 7, 2019 / 04:25 AM HST / Updated: May 18, 2019 / 01:41 AM HST
The witness list is out in the corruption trial of the Kealohas and several Honolulu police officers. Who is on the long list is as telling as who is not named, as federal prosecutors reveal how big a role they plan to make of a notary that they say is a fictional alias Katherine Kealoha created.
It's just over a week until the corruption and obstruction of justice trial begins, for former Honolulu police chief Louis Kealoha and his former deputy prosecutor wife, Katherine, along with three Honolulu police officers. An extensive witness list is out today.
"Normally the witness list is going to be extremely lengthy," said University of Hawaii law school faculty Ken Lawson. "If you get to the middle of a trial and you think, well maybe I should have put a witness on the list I didn't put there, you may not be able to call that witness."
The witness list includes 148 people that the prosecution and defense could call, plus 10 custodians of records for banks, phone companies, corporations, state government, even Facebook. The most of any single affiliation on the list are Honolulu Police Department staff — 37 current and 7 retirees.
Just being listed doesn't mean all will be called to the stand.
"You want to streamline your case because the jurors don't want to be there forever either," Lawson said, "so you don't want to take a chance of getting a jury angry at you by calling witness after witness after witness over the same thing."
This case centers on the alleged framing of Katherine's uncle Gerard Puana for mailbox theft. Puana is listed as are several Puana family members. Former HPD officers Niall Silva and Daniel Sellers are listed, expected after each cut plea deals for their actions surrounding the mailbox case. Not listed: Jesse Ebersole, charged with lying to the feds about his romantic affair with Katherine, with rendezvous allegedly paid for using her grandmother Florence Puana's reverse mortgage money.
"He may be called in the subsequent trials," Lawson said. "His testimony may not be relevant for this trial at all. He may be called in the other trials dealing with the finances."
The Kealohas have been charged in a separate financial fraud case; Katherine has been charged in a third federal case involving charges of drug distribution along with her brother Rudolph Puana, a Big Island pain doctor.
Former Honolulu Ethics Commission executive director Chuck Totto is listed, as is former HPD captain and Ethics investigator Leetha DeCaires, together among the earliest to flag suspicions of a mailbox frame job.
"So you may have the commission coming in saying, yes I did interview these individuals, here's what they told me," Lawson said.
Not on the witness list: Alison Lee Wong — Katherine Kealoha's purported assistant and frequent notary on financial documents material to several cases.
"If Alison Lee Wong's name is going to be prominent in this trial and the defense says she actually exists, somebody better produce her," Lawson said.
The feds contend Wong is just an alias for Katherine Kealoha, and they said in a brief filed last week they'll prove it, through a notary stamp shipped to Katherine's state office when she headed the Office of Environmental Quality Control, an e-mail registered from a City & County of Honolulu computer, a Facebook page accessed on the same device that logs onto the pages of Katherine's daughter and brother. The feds contend Katherine tried to convince others — what they call "implant memories" — that they'd met Alison.
"If you're telling me as my client that she exists, even if I don't believe you, I can't just say it," Lawson said, "so I'm in between a rock and a hard place. If you tell me as my client she exists, give me that address and I'll subpoena her. But if Idon't put her on the list am I admitting to the jury and to the judge she doesn't exist? She's a vital witness to this case, so I would want to call her if I need her. And if I don't call her what is that saying?"
KHON2 reached out to Katherine Kealoha's attorney for response about the Alison Lee Wong matter and the witness list, along with Louis Kealoha's attorney for witness-list comment. Neither has yet replied.
Jury selection will begin on May 13 at the Blaisdell Center. Trial is expected to last at least four weeks.

More Always Investigating Stories
Federal authorizations, legal challenges may have complicated state's enforcement of cease-and-desist against skydive company
by Gina Mangieri / Jul 10, 2019
Always Investigating exclusively revealed Monday that the state had told Oahu Parachute Center, months before its deadly crash, to stop operating. So how did the plane continue to fly despite the state's order? KHON2 found out federal versus state regulations can complicate enforcement.
If the state Department of Transportation had its way, the fatal June 21 flight would never have taken off in the first place because D.O.T. issued the company a cease-and-desist notice in April over business and aircraft registration issues, with a deadline of May 15. Making the order is one thing; enforcing it is quite another.
Company was told to stop skydiving before fatal crash; now ordered to vacate
HONOLULU (KHON2) -- The company in charge of the airplane that crashed in Mokuleia last month, killing 11 people, had been ordered to stop its skydiving operation well before the fatal crash. The company was given a cease-and-desist order from the state Department of Transportation earlier this spring, and today was told to leave. We found out there may be state labor department issues, too, which could make it difficult for families to collect what is owed when workers die on the job.
Sources tell Always Investigating that Oahu Parachute Center has been given a five-day notice to vacate its Dillingham Airfield facility. The plane that crashed in June shortly after takeoff was Oahu Parachute Center's only aircraft, leased from a mainland owner, and the company has not resumed operations since the accident.
Regulations drafted to rein in bike and scooter companies
by Erika Engle / Jul 5, 2019
HONOLULU (KHON2) -- The Caldwell administration has proposed a new law to regulate "shared mobility vehicle" companies such as bikes and scooters in Honolulu County, a move Mayor Kirk Caldwell told KHON2 would be coming when Always Investigating reported on the issue back in May.
The administration's draft bill would authorize the city to set aside parking stalls as designated bikeshare or scooter zones, and charge companies a fee to use them for business. It would require insurance coverage as high as $4 million, and companies would have to maintain a 24-hour customer service center. Those trying to operate outside of the framework face stiff penalties.

From Jewellery News Asia (JNA), English (Chinese) edition, June 2008, devoted to the fancy color diamonds, from the article - Rare colours: the most sought after diamonds.
Seren Diamond advertises in a number of trade, consumer & fashion magazines:
Red diamond is rated most unique and exclusive among the diamond dealers. "Red diamond is extremely rare and expensive, particularly those in Si1 to Vs clarities, as most red stones are pique. It's hard to extract red diamond from an Argyle mine in Australia, therefore a 1-carat fancy red or fancy purplish red diamond GIA can sell for more than US$ 1 million per carat, which makes red diamonds an ideal choice for both sophisticated collectors and those looking for a good investment. In the coming years, prices for red diamonds are expected to double," said Oren Seren, managing director of Seren Diamond Ltd.
Also highlighted at the Geneva sale was a pair of fancy green and yellow diamond ear-pendants. According to Christie's Geneva, green is one of the rarest colours that can occur in diamonds. Less than five diamonds graded fancy green saturation or higher have been sold at the auction in the last five years.
Mr. Seren has a similar sentiment. "Fancy vivid green and fancy intense green are particularly rare. This value has been considerable growth over recent years, fuelled by their uniqueness and the increasing awareness of fancy-coloured diamonds," he said …….
General manager of Rio Tinto's Argyle Pink Diamonds business, commentered: "Their pedigree as the rarest gems and their increasing scarcity, as the Argyle mine, the world's only reliable source of pink diamonds, which is likely to be exhausted within a decade, makes Argyle pink diamond a compelling investment option."
From Jewellery News Asia, Show Daily edition, Sept. 19, 2008
"Seren Diamond will introduce it's e-commerce website at the show, which will enable customers to find complete updated information of the stones available, purchase them online as well as place an order if the required stone isn't found an the site."
"In an effort to improve our service, we've been trying to put as much information online as possible, to make it as friendly as possible to our customers. Our online inventory includes both copies of the certificates and images of the stones which is extremely important with reference to the fancy color diamonds", said Oren Seren.
However, since conducting business online lacks the "personal contact", they regard the Hong Kong show as an important platform to initiate new relations and maintain the existing ones. "This year, we'll be presenting an exclusive collection of the natural colours that will include such rare colours as fancy vivid pink, fancy deep blue, fancy intense green; and of course, our fancy red and fancy purplish red diamonds", Mr. Oren added.

Bike commuting can be a challenge in the winter months. But if you're like us, you love a challenge! We also love the serene landscape and quiet, contemplative rides that winter affords. Keep pedaling through the winter with these handy tips.
Wear clothing that allows a little room for your body heat to build up, providing some insulation against the cold.
Yes, you do sweat even when the temperature is below zero. To stay warm, you need to wick the sweat away, so it doesn't turn cold and chilly. Fabrics such as wool and fleece are excellent for this. Avoid cotton, particularly right next to your skin.
Use a wind-resistant outer layer to cut the wind-chill factor.
For scarves, we like neck gaiters and circle (or "infinity') scarves because they are less likely to fly out and get stuck in bicycle spokes, and they're easy to remove as you warm up.
Wear thick wool socks and unventilated shoes. Wear a windproof glove/mitten combination so that your fingers are each covered but also snug together to keep one another warm in the mitten. If you can figure out what it takes to keep your toes, hands, and head warm, chances are the rest of your body will take care of itself.
Put it in a basket.
A front basket can be a handy winter accessory. You'll want to remove layers as you warm up on during your ride, and a basket allows you to store items while pedaling.
A set of fenders (paired with a rain cape, wind and waterproof gloves, and/or a balaclava, depending on the temperature) can transform a wet or winter ride (or worse—a wet winter ride!) from insufferable to super.
Don't forget lights at night! Cyclists should have lights in all seasons (and it's the law in NYC!) but it's especially important in the darker wintertime to add a front white light and rear red light to your bike so that you're ready when the sun sets early in the day.

Q: Proving the relative error of division. The problem says to show that the relative error for division on a computer is
\begin{align}\textrm{Rel}\left(\frac{x_{A}}{y_{A}}\right)&=\frac{\textrm{Rel}(x_{A})-\textrm{Rel}(y_{A})}{1-\textrm{Rel}(y_{A})}\\ &\approx \textrm{Rel}(x_{A})-\textrm{Rel}(y_{A})\end{align}
provided that the relative error of $y_{A}$ is small compared to one.
I know that $$\textrm{Rel}(x_{A})=\frac{x_{T}-x_{A}}{x_{T}}$$
and $x_{A}=x_{T}(1-e_{x})$ with $e_{x}$ being the error.
but I'm really not sure how to proceed from here.
Edit again: I emailed the professor and he sent out a class-wide email totally rearranging it so that's probably where confusion stems from. This is the new and actual problem.

A: Your notation is a complete mess (I made a correction, but it's still all wrong). You cannot start to trying proving something if you cannot make sense of that something. Try, for example, to work out a numeric example, to get some consistent notation.
I'll try.  I define $e_X = (x_T- x_A)/x_T$, so $x_A = x_T (1-e_X)$ ($x_T$ is the true value, $x_A$ the approximate or actual value, $e_X$ the relative error).
Then $$z_A=\frac{x_A}{y_A}=\frac{x_T(1-e_X)}{y_T(1-e_Y)} = z_T \frac{1-e_X}{1-e_Y} \approx z_T (1-e_X)(1+e_Y) \approx z_T (1 - e_X + e_Y)$$
where the last approximations assumes $e_Y \ll 1$. But the sign of the relative error is immaterial, hence $ e_Z= e_X + e_Y$.
Update: following the revised question:
$$z_A = z_T \frac{1-e_X}{1-e_Y} = z_T (1 - e_Z) \implies e_Z = 1 - \frac{1-e_X}{1-e_Y}
= \frac{e_X - e_Y}{1-e_Y}$$
Again, the denominator tends to 1 if $e_Y$ is small, and the numerator should be writen as $e_X + e_Y$ if we are computing propagation of errors.

What happens when the will abdicates and the body lets itself be guided by movement? What happens when it indulges in the pleasure of being lost in the vastness and emptiness of space? Looking for the right place for the body, a body whose bones, clinking like glass, are the only thing that remains.

Unified middleweight world champion, Canelo Alvarez, and the streaming service DAZN have agreed to a five-year, 11-fight deal that will pay the boxer at least $365m.
The deal is the highest-paying athlete contract in history.
DAZN became the broadcast home of boxing in the U.S. after HBO announced in September that it was getting out of the fight business. The signing of Alvarez kicks off the DAZN-boxing partnership with an exclamation point and plenty of zeroes.
Alvarez's first fight under the contract will coincide with his move to super middleweight. He will meet secondary world champ Rocky Fielding on December 15 at Madison Square Garden in New York.
His contract surpasses that of Giancarlo Stanton, who signed a 13-year, $325m pact with the Miami Marlins in 2014. He is now with the New York Yankees. In the post-Floyd Mayweather/Manny Pacquiao era, Alvarez emerged as boxing's biggest star on the pay-per-view fight circuit. HBO and Showtime typically charged $80 per fight, but on DAZN, his two fights per year will be available to those who pay $9.99 per month for the streaming service.
The 28-year-old Alvarez is from Mexico and has a 50-1-2 career record with 34 knockouts.

Maori lands
The Māori Land Court awarded the Owhaoko B&D blocks to Ngāti Tama, Ngāti Whiti and Ngāti Whiti Tama in 1888. Previously, certain Owhaoko A, B and D blocks were gifted to the Crown for use by Māori returned service men in 1917 however the land blocks were returned to the owners by 1972 as they were not suitable for settlement or farming.
From 1974, the land blocks were administered and controlled by the Tuwharetoa Māori Trust Board as the responsible Trustee with minimal inclusion of the actual landowners. This situation prompted a series of hui that took take place from 1993 to 1995 with the result being the establishment of the Owhaoko B&D Trust in February 1996.
The purpose given to the Trust is to "... provide for the use, management and alienation of the land and any other property or assets of the trust to the best advantage of the beneficial owners...".
Trust Development
From its inception, the Trust has continued the practice of recreational hunting and fishing through a recreational land use agreement with Heli-Sika which has generated an income stream and enabled controlled use of the blocks.
In February 2005, the Trust entered into a Nga Whenua Rahui Kawenata with the Minister of Conservation which not only serves to protect indigenous fauna and flora but provided a substantial consideration payment.
Over the years, the Trust has progressively established a sound operational base which has seen the appointment of a contracted Administrator and an Executive General Manager.
In recent years, the Trust has undergone change to increase its number of activities. Catalysts for change have been:
moving away from leasing its lands to a helicopter company and instead, engaging the helicopter company to provide helicopter services
entering into a three year Agreement with Westervelt, the owner of Poronui Station and Lodge to investigate employment and business opportunities on Trust land
engaging a Manager to manage the Trust affairs and to implement provisions of the Westervelt Agreement.
It is the objective of the Trustees to keep landowners, stakeholders, and interested members of the public fully informed about what the trust is doing, and where it is going.
