Log Shipping: It's Better Than Bad It's Good!
This is something of an epic post, so grab a tea and get ready…I'm probably showing my age by quoting an old Ren and Stimpy cartoon here, but to be fair it probably sums up log shipping pretty well. This post is focusing on using a read-only log shipping database for reporting purposes, and the limitations of read-only log shipped databases. I also share some monitoring scripts and a few ideas on how to improve restore performance without having to upgrade the hardware/software.
Despite the development of AlwaysOn in recent releases of SQL Server, log shipping is still a great way to set up a copy of databases to be used for reporting. One of the main reasons it is great is because, unlike AlwaysOn, it is available in less expensive editions like Standard and Web from SQL Server 2008 onwards. Sure, in 2016 AlwaysOn will be available in Standard, but in a greatly deprecated form, and you cannot read from the secondary. So it will be good for DR, but not for reporting (as an aside it still might be easier to set up log shipping for DR than AlwaysOn Basic because you need to setup a failover cluster. Read through the "how to set up Standard Edition Availability Groups" here.) However you do need to be careful though when setting up log shipping across different editions of SQL Server: whilst you can log ship between Enterprise to Standard/Web, if the database uses any Enterprise features then you'll need to log ship to an Enterprise edition of SQL Server. And because you'll be using the database for reporting, you'll need to get it licensed.
Restore Job: Well, you've probably already guessed what this job does! This job takes the restore settings of the database and restores the log files accordingly. And by restore settings I mean whether the database is RESTORE with STANDBY or RESTORE with NORECOVERY, whether all the log files are to be restored, and whether to disconnect users when initializing the restore. Because we're setting up a report server, we'd want to disconnect users, as we'd probably be waiting forever for users to be disconnected. This is a disadvantage of using a log shipped database for reporting, but really it is up to you to determine when the log can be restored and the needs of the report run times before deciding that a read-only log shipped database is the solution to your reporting needs (and this is really crucial). This job will also delete any copied log backups that exceed the expiry threshold.
--if the job is running now, then we execute rest of query, or we just stop here.
--set the percentage increase of the current run of job.
--if it is greater than percentage threshold then return job name.
You're all probably aware that you can also set jobs to email an operator if they fail. Whilst this can be useful, the frequency of the log shipping jobs will probably be set at several times an hour. And I really am not a fan of bombarding peoples inboxes with emails. Obviously if a log backup fails you want to get right on that and fix it, but possibly you could afford to have the reporting server fail a couple of restores before someone takes a look at it. Or you may wish to have a summary of the failed jobs over a 24 hour period sent out to first level support for them to escalate. So a more pragmatic solution would be to create a job that would check if any of the jobs have failed within a set time frame (say, below the restore threshold but higher than the frequency of the jobs failing.) An example of this sort of alert that emails if any jobs have failed in the past day is below.
Another limitation is that using the RESTORE with STANDBY mode is far slower to restore than the NORECOVERY mode. This is because the read-only database needs to be transactionally consistent to report from, so any uncommitted transactions need to be undone during the STANDBY restore. So if you have a large log backup that is pretty much uncommitted transactions (think index rebuild of a capacious table) then all the pages of that table will need to be written to a transaction undo file (.tuf). Come the next restore this undo file will have to be re-written back to the database before the next restore can be started. So lets imagine you have an hour-long ETL process overnight, and you take 4 backups in that time, then the undo/redo process will have to be repeated several times, taking a very long time: I once saw an log file being restored that was 6GB of uncommitted transactions, and the tuf file created at the end of this was a massive 28GB! This restore took 2 hours to complete! And the reason why the tuf file was so much bigger than the log file was because it has to copy all the pages affected to the tuf file.
Move delete job out of restore job: If the backup files are large, it may take some time to delete these files from the backup folder. As this task runs as part of the restore job, you could create a delete job yourself to run during a time that the restore job is not running (even when the database is in read-only mode, you won't be affecting the database as the delete job will just access the file system.) Then re-configure the log shipping copy job to delete files at a very high threshold so that the restore job will never have to delete files. A sample of a custom delete job is below: this will delete any files that are 12 hours older then the last restored log file on the secondary server. Create a custom delete job on the server and add this as a step and schedule to run whenever you need it to. You still have to be careful about how many files you keep in this location though, as the restore job still has to scan the contents of the folder. Keep in mind that this is only a copy of the files to be restored, not the actual backup files themselves (unless you are restoring from the original backup location). So you can keep the number of files here at a relatively low number by keeping the threshold small.
Start the default restore job using msdb.dbo.sp_start_job.
SET @db_mail_body =N'<h3>The databse '[email protected]Database+' is in the incorrect state. The job '[email protected]restoreJobName+' has completed restoring all backup files.
The database '[email protected]database+' is '[email protected]DBState+'. The restriction accces is '[email protected]DBUserAccessState+'. The database '[email protected]database+' is '[email protected]DBIsInStandby+'.
However, even with a custom job you may still experience large delays: if the restore time is only scheduled to run between 5AM to 8AM, and the last restored file still has a large number of uncommitted transactions, it will still take a long time to restore this final log file. So you need to look at the schedules of jobs running on the server and what data is needed for reports to make sure you are not left with a large .tuf file at the end of the process.
Outside of using the database as a reporting database, some people may think that they can run CHECKDB on a log shipped database. Unfortunately this is not the case, and you will either have to run on the production server or a BACKUP/RESTORE of the primary database. You also need to be careful about which version you are restoring to: you cannot RESTORE with STANDBY to a later version of SQL Server. This happened to a colleague of mine when he was trying to set up log shipping, a time consuming mistake that is probably made quite frequently, especially as it is possible to log ship to a later build using the NORECOVERY option. Another popular myth is that running the primary database in the bulk logged recovery model will make the backup files smaller. This is not true.
Ultimately, using a log shipped copy of a database for reporting purposes is perfectly feasible, providing you know the limitations of the technology and if it will fit into your needs. Despite these limitations, it is by no means a bad technology: in fact logshipping really is a good option in the right circumstance, it might just not be right for your reporting needs. You'll never have your secondary database available for reporting 24/7, and unless your database is very small with relatively low activity occurring, you'll probably have to manage restore times with a custom restore job. So you'll need to manage the expectations of the users when implementing a read-only copy of the database. But don't let that put you off: in the right situation, using a log-shipped read-only database for your reporting needs is quick and straightforward to set up and is very robust.

On August 9th, the bodacious 2015 Band Officers departed on their annual retreat. This year the officers went to Tampa for a visit to Busch Gardens. This closely knit group of band geeks was able to bond with each other through many inside jokes, selfies, lip-sync battles, and Bible devotionals.
As musicians, we are naturally inclined to push ourselves to accomplish our goals. During a Ropes Course at FIU, we were forced out of our comfort zones and had to do everything to the best of our abilities. Solely relying on the hands of our fellow officers, one by one, each officer had to climb and trust in the person holding their safety rope. The bonding exercises we performed brought us even closer together as a family.
We had the most fun sitting in our hotel room, crying with laughter at our band directors and friends lip-synced to songs like Bad Blood, Shake it Off, Chandelier, Party in the U.S.A., and Careless Whispers. In the end, Mr. Miner edged out for the win with his song against Joshua Goff. We now plan on holding annual lip-sync battles exclusively, for the Officer Retreats.
Finally, the most beneficial aspect of this trip was our time spent praying and teaching each other about the Word. We were able to deepen our relationships spiritually with God and our friends. Nothing is more powerful than being able to exchange prayer requests and knowing that you will be prayed for.
The Band Officer Retreat was the most laugh-filled, bonding trip I have ever had the pleasure of experiencing. We are all extremely blessed to have been given this opportunity. Those of us who are not yet seniors, look forward to the next trip. And those who are seniors, will be missed by the younger officers in the following year.


Paul Marcus' 30 plus years in film and video production as well as the independent films he has directed make him uniquely qualified to be on the board of directors for Parallel Studios. He is a producer of feature films, television series, documentaries and commercials, working with industry icons such as John Sayles, Wim Wenders, Alex Gibney, Steven Soderburgh and Terrence Malick. His own films include Mercurial Son (2005), and Underway (2008). He was part of the volunteer production team for the the 2010 Currents Video exhibition.


The doorphone calling panels are special devices needed for audio or video communication between visitors and hosts. They are mounted in the outer side of the building and require certain technical features. The main component units are a microphone, a speaker, a video camera, and a call button. The resented panels can additionally be equipped with backlighting, controller, reader etc.
The operational principle of this unit is based on the following: after pressing the button on the panel, the signal is transferred to the apartment, and the device owner can see who is behind the door. A speaker and a microphone provide communication between the visitor and the host, and you have just press one button to let the guest in, and the door will be unlocked.
The purchase of the calling panel for private use – will greatly improve your safety due to the simple control over the visitors of your apartment or office. In the conditions of modern life, such precautions will not be unnecessary regardless of whether you live in a block of flats or a private cottage.
The doorphone video panel doesn't have a complicated design, therefore the classification of the panels will be quite simple. The first thing which is worth mentioning is two types of images: color, and black and white. The mounting types is also essential: attachable, cut-in or combined. The doorphone calling panel can be configured for one or several users. As for the camera resolution, then this parameter has a secondary meaning and it needs to be selected depending on the needs of the future users themselves.
As a rule, the color calling panel is more popular today, since black and white calling panels are gradually losing ground. However, if you want to save money, it is black and white devices that will be the most profitable. Device reliability will depend on the mounting type – cut-in or attachable. Today the best thing is to use cut-in models, because they have the best protection against vandalism. You can protect calling panels from adverse weather conditions with the help of special protective visors, dust-proof buttons, rubber plugs, as well as special tenacious alloys as the material of construction.
Affordable prices for the calling panel have made this device quite popular for security in residential or office space. Inexpensive and easy-to-use calling panel will make you feel safe, and the owners of such devices were able to check it fully. However, if you are going to purchase this device, then it is worth taking into account some od its features. What kind of calling panel is better?
The first thing to pay attention to is structural strength. If your house or office is located in a socially deprived district, then you should give priority to the most reliable devices that are well-protected against vandalism. In addition, such panels will stand weather conditions such as low temperatures, high humidity, dust and dirt much easier.
Another important parameter is the functionality of the device. Typically, the average user will have enough of the usual options, but certain additional functions can significantly affect the comfort of use by increasing it. The image quality will depend on the camera technical characteristics: the higher is its resolution, the better image quality will be. If the panel is equipped with viewing angle adjustment function, then this will also provide some advantages.
Once you are thinking about buying a panel, make up your mind about the mounting type, power settings and the number of subscribers, this will also determine the doorphone panel model. If you take our pieces of advice, you will be able to choose a device that fully meets your requirements and provides an optimal level of comfort and safety.

Tokyo Olympics 2020 | What to watch out for when surfing at the Olympics
2 years ago Richard Powell
For the first time in the Olympics
Surfing was developed as a sport in the Pacific Islands. The Duke of Hawaii Kahanamoku, who won three US gold medals in swimming at the 1912 and 1920 Olympics, is considered the "father of modern surfing." The first world championship was organized in 1964. With the addition of surfing to the Olympic program, its recognition as a sport is completed.
What: surfing
Where: Tsurigasaki Surfing Beach
When: Sunday, July 25 – Wednesday, July 28
Where to see it: Eurosport 1 & Discover +
Favorites: Gabriel Medina, John John Furance, Cana Igarshi, Carissa Moore, Stephanie Gilmore
What is surfing?
Surfing should not be confused with surfing, which is the sailing discipline in which Dorian van Risselberg won gold at the 2012 and 2016 Olympics. In surfing there are different disciplines with different types of boards. Twenty men and women compete for medals on short boards in Tokyo. The length of the short board is about 180 cm. The surfing championship takes place over four days. Surfers can be found on Olympic waters July 25-28. The finals will take place on Wednesday, July 28.
The surf tournament is held in rounds with a knockout system. In the first round, four athletes were in the water at the same time. The surfers with the most points advance to the third round. Players who finished third and fourth will get a second chance in the second round. From the third round, heated competitions are held in which only two athletes are in the water at a time. The winner of the heat advances in the tournament.
John John Florence at Billabong Pipemasters 2016
The heat lasts thirty minutes as surfers are allowed to ride a maximum of 25 waves. For each wave driven, the surfer receives points from the five-member jury. The jury judges difficulty, speed, creativity, and flow. The highest two waves of points will count towards the athlete's total score. The surfer who gets the highest score after thirty minutes wins the heat.
Who should you pay attention to?
Among men, American men have historically been the strongest. The biggest name on the American team is John John Florence from Hawaii. Florence, 28, won the World Surf League title in 2016 and 2017. Florence's biggest competitor comes from Brazil. The country has not been a part of the absolute top for a very long time, but is now an indispensable part of international surfing. Brazilians Gabriel Medina (27) and Italo Ferreira (27) have won the last two editions of the World Surfing Championships. Homeland pins its hopes on Kanna Igarashi. Igarashi was born and raised in California, but Japanese parents. He also comes from that country. The fourth-placed surfer will go to the Games with a real medal chances.
The women's match looks like a duel between the United States and Australia. The big favorite is Carissa Moore (USA). In the state of Hawaii, one day is named after her. On January 4, Hawaiians celebrate Carissa Moore Day. Moore became world champion in 2011, 2013, 2015 and 2019. She will top the championship in 2021. Moore will be challenged by Caroline Marks (US), Stephanie Gilmore (Australia) and Sally Fitzgibbons (Australia).

Hello Yvonne: Florals & Denim!
Hello! Hope you had a nice mother's day weekend. I spent mine with my sweet mother in law who chose to house hunt for our potential homes. Jason and I are considering our first home and finding it to be interesting as we both express our must haves. Mine is a huge walk in closet, a certain number of bedrooms and more, while hubby just insists on refrigerated air cooling system ha. Do you have an ideal home must have?
Anyway I wore one of my favorite comfortable jeans/jeggings this weekend and simply thought to pair it with this loose sort of cropped flowy floral zara top. I love that I can eat a lot with this top on and not worry about it showing. I think flowy tops can be so forgiving.
Jeans- Express (Similar), Top- Zara (Similar), Heels- Forever 21 (Here), Jewelry- Forever 21/ Rue 21/ Express (listed in previous posts), Bag- Marc Jacobs (Here).
This is such a lovely outfit, the floral top is beautiful.
This is a pretty outfit on you and I love the colors of your flowing top.
Love your floral top! You look so cute!
Love the floral top Yvonne! Very cute and looks great with the jeans!
That floral top is everything! It looks amazing on you! A Walk-in closet a must - have :) Happy house-hunting! You are going to have so much fun!!
I'm glad to know I'm not the only one. Thanks, & thanks for dropping by!
Thank you!! I'm glad you think so!
Yes I agree, a def must have haha ;) thank you Deborah!
great look , i'm loving the blouse.
Absolutely Love this casual look, the top is super gorgeous!


Identity fraud is simply theft of your identity. It is when someone unlawfully and without your permission uses your personal information such as your name, your Identity Number or other identifying information, to commit fraud or other crimes.
This information can be stolen from your home, car, your wallet and criminals will even go through your rubbish bins to obtain personal information from documents. Cyber-crime is on the increase, and personal and confidential information can be obtained via the internet, emails, spoofed websites and even social networking sites such as Facebook and Twitter.
Phishing: Use of email "phishing" scams requesting you to provide your private and confidential information via a website link is an essential tool currently used by these conmen. SARS will never ask you for information such as your eFiling details (login details, passwords, pins, credit/debit card information, etc.) in an email or over the phone.
Refund Scams: An identity thief can use a legitimate taxpayer's identity file a tax return and claim a refund fraudulantly. Another threat is that the criminal makes use of your information to change the banking details on your profile. See some examples of scams and phishing.
Identity Theft: The latest scam involves taxpayers being called by a person purporting to be a SARS employee, to inform them that SARS owes them money. SARS will never notify you about refunds by telephone or email.
Fake SARS auditors/employees: Scam artists purporting to be SARS auditors/employees contact businesses to inform them that they are under investigation and that an audit is going to be conducted. The business is then provided with a fake letter supposedly from the Audit Section, requesting the client to provide full co-operation with the "auditor or employee".
You receive an email requesting eFiling details (login details, passwords, pins, credit/debit card information, etc.).
Visiting your nearest SARS branch to verify the information.
If you have become the victim of identity theft, you should immediately notify SARS, report it to the police and close all bank accounts.
Top Tip: Protect yourself again identity theft or identity fraud.

Q: Why is the best time complexity of the sorting problemo O(nlog(n)) when radix sort is O(n)? In my textbook, I am told that the sorting problem has a time complexity of  θ(n*log(n)). However, it is simple to show that Radix sort is O(n). Doesn't this contradict what is said? Isn't the lower bound time complexity for sorting problem thus θ(n)?
Edit: StackOverflow won't let me put "problem" in my title so "problemo" has to stay.

A: Ω(n*log(n)) is a lower bound for a comparison sort, not any existing sorting algorithm. Radix sort is not a comparison sort.

A: Generally speaking, the time complexity is O (mn), but it can be approximated as O (n) ,when m is much smaller than n, and it is not strictly wrong to say that there is no ordering of O (n).

Die Methode des kritischen Pfades (auch Tätigkeits-Pfeil-Darstellung genannt; englisch critical path method, CPM) repräsentiert die Vorgangspfeil-Netzpläne, eine spezielle Netzplantechnik. Sie wurde 1956/57 vom amerikanischen Chemiekonzern DuPont in Zusammenarbeit mit den ADV-Spezialisten Remington Rand Corp. entwickelt und auf einer UNIVAC I implementiert, um große Investitionsvorhaben sowie Instandhaltungsarbeiten bei Chemieanlagen systematisch zu planen und zu überwachen.

Grundlagen
Die Methode des kritischen Pfades verwendet die Darstellungsform des Vorgangspfeils. Bei CPM-Plänen werden die Vorgänge als Pfeile, die Ereignisse als Knoten und die Anordnungsbeziehungen wieder als Pfeile dargestellt. Voraussetzung, um mit einem Netzplan sinnvoll arbeiten zu können, ist, dass alle Vorgänge des Projekts mit der jeweiligen individuellen Dauer richtig zueinander in Beziehung gesetzt werden.

Erstellung
Folgende CPM-Regeln sind zu beachten:
 Ein Vorgang kann erst beginnen, wenn alle vorhergehenden Vorgänge (Vorgänger) abgeschlossen sind. Dabei fällt das Anfangsereignis mit dem Endereignis des vorhergehenden Vorgangs zusammen (Ausnahme erster Vorgang).
 Müssen mehrere Vorgänge beendet sein, bevor ein folgender Vorgang (Nachfolger) beginnen kann, so enden sie im Anfangsereignis des Nachfolgers.
 Können mehrere Nachfolger beginnen, nachdem ein Vorgänger beendet ist, so beginnen sie im Endereignis des Vorgängers.
 Haben zwei oder mehr Vorgänge gemeinsame Anfangs- und Endereignisse, so ist ihre eindeutige Kennzeichnung durch Einfügen von Scheinvorgängen sicherzustellen. Scheinvorgänge sollten als gestrichelter Pfeil, der besseren Übersichtlichkeit wegen, dargestellt werden.
 Beginnen und enden in einem Ereignis mehrere Vorgänge, die nicht alle voneinander abhängig sind, muss die Eindeutigkeit ebenfalls durch Scheinvorgänge erreicht werden.
 In einer Folge von Vorgängen können beliebig viele Scheinvorgänge eingefügt werden. Sie dienen der logischen Verknüpfung und können die Übersicht erhöhen. Scheinvorgänge sollten als notwendiges Übel angesehen und deshalb generell sparsam angewendet werden.
 Kann ein Vorgang beginnen, bevor der Vorgänger vollständig abgeschlossen ist, so muss der Vorgänger unterteilt werden. Diese Regel erhöht nicht unbedingt die Klarheit des Netzplans.
 Jeder Vorgang darf nur einmal ablaufen, es dürfen keine Schleifen auftreten.

Beispiel eines CPM-Netzplans

Rechnerische Darstellung

Wenn die benötigten Informationen über Dauer, Termine und Anordnungsbeziehungen (Begriff siehe Netzplantechnik) vorliegen, kann die Berechnung des kritischen Pfades unabhängig von der graphischen Darstellung erfolgen.
Berechnet werden die Zeitpunkte für die einzelnen Vorgänge und die sich daraus ergebenden Pufferzeiten. Jedes Ereignis und jeder Vorgang haben im zeitlichen Ablauf eine früheste (mögliche) und eine späteste (erlaubte) Lage.

Die Berechnung erfolgt in zwei Schritten:

 Zunächst erfolgt eine Vorwärtsterminierung, bei der ausgehend vom geplanten frühesten Startzeitpunkt des Projekts nacheinander für alle Vorgänge in die Zukunft hinein gerechnet wird. Damit ergeben sich die frühesten Anfangs- und Endzeitpunkte aller Vorgänge.
 Bei der Rückwärtsterminierung wird umgekehrt vorgegangen; vom Zeitpunkt des geplanten Projektendes wird nun in Richtung der Gegenwart gerechnet. Es ergeben sich die spätesten Anfangs- und Endzeitpunkte der einzelnen Vorgänge.

Besteht für einen Vorgang zwischen dem Ergebnis der Vor- und der Rückwärtsrechnung eine Differenz, so liegt eine Pufferzeit vor. Ein Vorgang, der eine Pufferzeit besitzt, kann zwischen dem frühesten Anfangstermin und seinem spätesten Endtermin um diese Pufferzeit verschoben werden, ohne dass dadurch die Projektdauer negativ beeinflusst wird. Ein Weg durch den Netzplan vom Start- zum Zielknoten, bei dem kein Ereignis Pufferzeiten hat, wird als kritischer Pfad bezeichnet. Eine Verzögerung bei einem der Ereignisse des kritischen Pfades hat immer eine Verzögerung des Endtermins zur Folge.

Vor- und Nachteile der Netzplantechnik allgemein
Vorteile:
 Zwang zum exakten Durchdenken des Projektablaufs
 übersichtliche Darstellung der Abhängigkeiten
 Möglichkeit der Minimierung der Projektdauer
 höhere Sicherheit in der Termineinhaltung
 deutliche Hervorhebung von Projektengpässen
 Rechtzeitiges Erkennen möglicher Verzögerungen und Abschätzen von Konsequenzen

Nachteile:
 Ungewissheit in der Zeitplanung
 Vorliegen unterschiedlicher (subjektiver) Auffassungen zum Projektablauf
 Pufferzeiten werden schnell durch Aufblähen der einzelnen Aktivitäten verbraucht

Vor- und Nachteile der Vorgangspfeilnetzpläne (CPM-Netzplantechnik)
Vorteile:
 Einfache Berechnungsregeln und daher einfache Programmierung
Nachteile:
 Modellierung schwierig, da wenige Möglichkeiten bestehen, um komplizierte Abhängigkeiten zwischen verschiedenen Vorgängen einfach zu beschreiben. Siehe insbesondere die Regeln 4 bis 7. Wegen dieses Nachteils werden heute in der Praxis kaum mehr Vorgangspfeilnetzpläne, sondern nur noch Vorgangsknotennetzpläne verwendet.

Down Under-dogs: meet the players fighting for a thriving Australian esports industry
by Iain Lew
Clocked
Photo: Fortress Melbourne
While the Australian esports scene is still in its infancy, several pioneers are making waves in their segment of a global billion-dollar industry.
The world of esports is both intensely familiar and completely alien; there are giant, roaring crowds in sold-out football stadiums, suited commentators and pundits (known as casters in esports) around a glass table, sponsorships from the likes of Mercedes-Benz and Mastercard. And yet, the spectacle is not seen on a pitch, but on a screen. The players themselves can be seen on stage, but the focus is towards the avatars they control.
Whether playing as one of the 150+ champions in League of Legends or as an attacker in Counter-Strike: Global Offensive (CS:GO), Australian esports athletes are making their mark on global competition. Anathan "ana" Pham has won The International for Dota 2 (the game's equivalent of the World Cup) twice, earning millions of dollars in prize money, while Justin "jks" Savage is regarded as one of the best CS:GO players in the world.
Common in South Korea and China, this sort of scene is yet to be considered standard in Australia. Beyond low quality internet and slow cultural absorption, esports is yet to establish a foothold in a country geographically isolated from the rest of the world and with a focus on traditional sports. Despite these challenges, several local trailblazers are looking to make a mark on an industry worth more than a billion dollars with a global audience of around 500 million.
This article appears in print in Happy Mag Issue 15. Grab your copy here.
As with any new competitive field that comes up, organisations and teams are birthed alongside the industry, forced to roll with the growing pains. For the Australian esports scene, its biggest ever challenge is happening right now. Riot Games – the company behind League of Legends – has shuttered its Oceanic esports operations, closing its Sydney office and dissolving the Oceanic Pro League (OPL).
Suddenly, whole teams were left without jobs and while Riot did provide a reprieve in opening access for Oceanic players to play in the North American League of Legends Championship Series (LCS), the news has come as a huge blow to the industry.
Most of Australia's esports clubs were founded as League of Legends teams, so to see their historical foundation disappear overnight has been shocking to say the least. Despite this road bump, there remains hope that organised play will return in some form; Riot will still be holding Oceanic qualifying tournaments for the 2021 Mid-Season Invitational and World Championship.
The Head of Operations at ORDER, one of Australia's most storied esports organisations, Naithan Briffa expressed hope for the Australian grassroots movement and how the release of Riot Games' first-person shooter VALORANT will provide a fresh opportunity.
"If there weren't a professional league spun up in the wake of the OPL it would be hard to develop talent, but definitely not impossible. The grassroots esports environment continues to thrive in Oceania, and given the great success of Oceanic imports to the LCS and LEC [League of Legends European Championship] competitions I am confident that global talent scouts would continue to keep their eye on the scene."
Besides the Rise of Valour tournament sponsored by Riot, ORDER hosted their own VALORANT tournament in the form of the ORDER Oceanic Open. It appears that the organisation is determined to ensure that VALORANT does not go the way of League of Legends.
Briffa stated that ORDER hosting its own tournament was a signal that the region has to follow the lead of the rest of the world in proactively forming a pro infrastructure.
"The cutting edge leagues around the globe have terrific governance… and while we may be unable to clone those operational structures we can certainly benefit from adopting the mindset."

Though most traditional athletes stayed at home during the pandemic, esports had the advantage of being able to be conducted online. Despite this, there were various challenges that came from this period, namely the inability to gain wisdom from flying to and playing in international tournaments.
Nonetheless, the ease of this adaptation demonstrated the low barrier of entry that esports has and the flexibility inherent to the scene, which has made Briffa hopeful of future prospects.
"The pandemic has allowed audiences a chance to spend a bit more time watching the terrific domestic esports that we are able to produce, and I think will have positive benefits in terms of mainstream and commercial adoption."
As with traditional sports, Australian esports fans have developed a reputation among the international community for their fervour and humour. This was perhaps best demonstrated at IEM Sydney, where fans stacked pizza boxes and religiously chanted "Nutri-Grain". The notoriety of Australian fans has not gone unnoticed by Briffa in describing what Australia brings to global esports.
"2019 and 2020 have been as good an example as one could ask for in terms of watching the elite Oceanic players and staff head off internationally as our region gains the genuine interest of some of the biggest organisations and operations globally, and the Australian fanbase that follows them is a massive key in achieving a true global status with the most invested fans."
The Alienware-sponsored ORDER was founded in 2017 by Jake "Spawn" Tiberi, a League of Legends caster who commentated the Chinese league and various international tournaments. For the past few years, Spawn served as the team's general manager and coach as it expanded from League of Legends into various other games including CS:GO and Street Fighter V, all while continuing to cast. But following the dissolution of the OPL, Spawn resigned from his positions to pursue an international opportunity as the head coach of Team Liquid Academy in Los Angeles.
Spawn is just one of several Oceanic talents that have left the region for greener pastures. Despite the fears of a brain drain occurring, Briffa is optimistic that Spawn will prove to be an excellent and hard-working representative of Oceanic League of Legends and by extent, Australian esports as a whole.
"I think his legacy will be felt in his extraordinarily deep understanding of the Oceanic League of Legends scene, and his burning desire to see the premium talent we have available get to prove themselves on the international stage. Spawn is as genuine an expert on League of Legends as you could hope to find of anyone in any industry, and I know that he will always continue the fight to have Oceania represented at the highest levels of competition."
Despite the various challenges that come with running an esports team in Australia, it appears that the region is progressing towards becoming a major contributor to the global industry. The scene seems to be channelling underdog qualities common throughout Australian competition, those of determination and perseverance through whatever challenges. It permeates every level of Australian esports, even the venues.
When looking across the world and how it facilitates live esports events, it has chosen to build entirely new infrastructures. Places like Nexon Arena in Seoul, the 7,000-seater Zhongxian E-Sports Stadium in Chongqing, China, and the 100,000 square feet Esports Stadium Arlington in the United States highlight the growth of the esports industry into something completely different from traditional sports.
Like virtually every single business in 2020, Fortress Melbourne was faced with the challenge of COVID-19 and lockdown. The venue shut its doors six days after its grand opening in March to "protect the health of our team and patrons".
Fortress Melbourne CEO and co-founder Jon Satterley described his 200-seat venue as "the home of gaming" and how it's in a "category of its own", being Australia's largest esports venue capable of live production.
"No video, no presentation, no photos can do real justice to the actual venue. When people enter… their jaws literally drop and they cannot believe something like Fortress actually exists. The elevation of all manner of gaming happens as a direct result of being inside Fortress which is kind of like the Disneyland for Australian gamers."
Located in the centre of Melbourne's CBD, the 2,700 square metre gaming hub includes two licensed bars, a restaurant, and 160 Alienware gaming PCs open to the public. There's even facilities for streaming, plus tables where you can sit down and play board games. But much like its overseas counterparts, Fortress Melbourne is not simply an esports venue.
"Interestingly, Fortress Melbourne is emphatically not described or promoted as an esports venue. Rather, we see our mission… to ignite the spirit of gaming. It is our belief that if we create social hubs that allow that spirit to take hold… we are fostering the conditions for all manner of gaming cultures to grow and develop."
During lockdown, esports viewership numbers dramatically increased and new opportunities presented themselves. The most notable esports event during lockdown was the release of Riot Games' first-person shooter and CS:GO competitor VALORANT. An esports infrastructure was set up for the game upon release, including Riot-sponsored tournaments which Fortress hosted online.
"Fortress's big story during the COVID lockdown was our Rise of Valour VALORANT tournament(s) and we have high hopes that this game, and Fortress's stamp on it, will become a major part of future competitive gaming events. We'd love MEO [Melbourne Esports Open], for instance, to hold a slot for a pro VALORANT contest that Fortress could also help promote/manage."
As it often happens, Melbourne remains the testing ground for innovative ideas before they are exported elsewhere in Australia. Having somewhat proved itself, Satterley did reveal that Fortress is looking to expand, stating:
"Specifically, Fortress is searching for the next flagship venues across Australia to continue this mission. We hope to have at least two more major Fortresses open by the end of 2021, with an eye on Sydney in particular. In addition we are developing many more online events, in tandem with publishers, that will grow the scene and build bigger gaming communities, online and in real life as they meet and socialise in our centres."
"I guess for us the decision to build the first Fortress in Melbourne was mainly because that is where we (as the founders) are all from, so it was an easy choice to do the first one in your own backyard. I also think that Melbourne is often the place where the pioneering stuff happens – the weird, creative, risky ventures – and once they mature, the head offices inevitably end up in Sydney!"
It appears that both Sydney and Melbourne will add esports to their long list of competitive phenomena, including coffee (Melbourne), fashion (Melbourne), and weather (Sydney). For now Melbourne is winning, with the next IEM tournament to be hosted in the Victorian capital which also hosts the Melbourne Esports Open. And with all this, Fortress is setting itself up to be in the centre of the esports revolution.
The Australian esports industry is at its most prosperous and most destitute moment in its short history. On one hand, the closure of the OPL has placed a major foundation of the field in considerable jeopardy. But COVID-19 proved to be a blessing in disguise by boosting viewership numbers and mainstream awareness. With the release of VALORANT providing a new opportunity, the continued exporting of Aussie talent to major leagues overseas, and the development of physical infrastructure, there is a pathway towards Australia becoming a major player in the global esports ecosystem.
To be in that position, Australia must contribute something regionally unique and it is clear what that is; the tenacity and persistence that has been exported from traditional sporting culture. Heroes who punched above their weight at the highest level like Tim Cahill and Steven Bradbury are part of Australian sporting folklore and it seems that, eventually, esports practitioners will be added to this tapestry.

A Storyteller's Story
Submitted by Elaine Lipson on Thu, 2010-08-26 01:00
Jude Hill's Spirit Cloth stitches global techniques into personal narratives
In the best tradition of folk artists, Jude Hill is a storyteller. Her textile work blends piecing, appliqué, kantha stitching, and embroidery into strong, organic whole cloths rich in imagery and revelation. The materials—raw fragments of fabric, always with a history—and the motions of repetitive hand stitching, are intimate and familiar; the concepts mythical, imaginative, evocative.
Jude calls her work spirit cloth, and writes a blog under the same name that has brought her technique and her interior world to thousands of readers. Often beginning from the simplest of concepts, such as a recent series on dots, works emerge and are chronicled on the blog, day by day and stitch by stitch. The finished textile pieces reference the natural world, textile history, and Jude's own internal compass as it measures time, emotions, and impulse. "What if . . . " is one of Jude's favorite ways to start a sentence or a work session, and is also the name of a companion blog that focuses on the practice of asking that most daring question and exploring the infinite variety of possible responses.
With aspirations to be a children's book illustrator, money concerns forced Jude to drop out of the School of Visual Arts in Manhattan and take a job as a trainee handweaver in a textile company. After sewing as a child, learning to weave was something she'd always wanted to do. "I loved it," she says. "I got very much involved in fabric. I got into woven fabric design and dropped everything else. I started collecting fabrics, and taught myself to weave and design them."
On the daily train ride into the city, Jude began to stitch with needle and thread again, and the pieces of her spirit-cloth path began to come together as she embroidered small pieces of found fabric. The stitches became drawing tools, her work in the fashion and textile industry provided an endless supply of scrap fabric, and the long commute gave her time to incubate her ideas. "It took over my life," she says. "I lost interest completely in [other things] I was doing. I didn't think about it as art; I didn't ask anybody if they liked it or not. It fed my creative desire for storytelling and it developed on its own without any pressure. It became very personal. I would just make these cloths that went on and on and on."
If Jude's approach was entirely intuitive, she brought years of an evolved design sense and stitching skills to the process. Her imagery—toothy lions, cracked hearts–sometimes echoes childlike or primitive forms, but like the classically trained musician who turns to improvisational jazz, the execution is anything but primitive. Jude came to "the point of understanding that all I needed was a running stitch," but could only come to that point with years of textile exploration behind her.
The soul of the cloth also comes from Jude's eye for textiles that leaves no piece unconsidered. "Using existing fabrics was just common sense. I had a pile of fabrics [from the work I was in] and I've always been interested in ethnic textiles and collected pieces of fabric. I traveled around the world and studied different cultures and techniques." Her intention was and is to give structure to these remnants, in a lasting, skillful way – to make them hold together, she says – and to tell a story in the process.
Jude's work also tells a story of gifts given and received. "Someone told me I should start a blog, and I thought it was a good idea but didn't know what to name it," she says. "I had the notion that everything I was doing was a gift, and telling a story, and I was creating this thing from nothing and sharing it with someone, and sharing the spirit of it. In general it's the spirit of the thing. Part of what I do is still gift-giving, and now people send me stuff from all over the world." Spirit Cloth became not only the name of the blog but code for a slow and authentic approach to fiber and stitching.
The storytelling aspect of the cloth sometimes includes actual words, as in her gorgeous lion quilt (see accompanying slideshow). "I do think of the work as folk art, and have only considered it that way recently," Jude says. "Folk art for me doesn't have anything to do with copying a style that's been established along the way. It's something that develops on its own without any value or category attached to it. But because of the way the world is now, it's got to be something that's multicultural."
Like many folk artists, Jude's work is intrinsic to her life but doesn't free her from financial concerns. "Right now I'm selling, so [themes in the work] are being repeated," she says. "But the real development of my style is always separate from that. It's a personal expression that contains everything that you know that's practical and useful."
The future of folk art will depend on education, in the absence of oral or family traditions that keep skills alive through the generations, Jude comments. She's considering teaching workshops that encompass the whole of her spirit cloth philosophy. "It should be something that's educational in terms of fabric and culture and examples. The work I see doesn't have enough detail. It's not connected to a person or a story."
That connection is Jude Hill's gift, not just to textile artists but to lovers of beauty and stories everywhere. In her commitment to the handmade object, the simple stitch, and the integration of fragments of fabric that could easily be lost, in her love of story and the constant expansion into the realm of what-if, Jude's work is the very essence of spirit. Sometimes irreverent, sometimes concentrated into the purest of emotions or visual concepts, sometimes simply joyful in the making, it's contemporary folk art at its best.

Henry James is one of the giants of American literary history. From the novella "Daisy Miller" and classic short stories such as "The Turn of the Screw" to the popular short novel Washington Square and intricately woven and highly complex later novels such as The Golden Bowl and The Ambassadors, Jamess work is a required stop on any journey through our nations artistic and cultural heritage.An undisputed masterpiece, The Portrait of a Lady is arguably Jamess most popular work, and certainly the finest of his early novels. It focuses on Isabel Archer, a young, intelligent, and spirited American girl, determined to relish her first experience of Europe.
