What is Garbage Collector?
Garbage Collector is a form of automatic memory management
The component takes care about reclaiming memory that was allocated for objects needed earlier. There are programming languages that don’t provide this functionality and a programmer has to manage memory manually.
Java Virtual Machine (JVM) includes garbage collector. It means that all JVM-based languages e.g. Java, Kotlin, Scala, Clojure supports automatic reclaiming unused objects.
There are many algorithms that might be applied to check if an object is not needed and memory for the object might be reused for other objects. The main idea of them is if there are no references to an object, the object is unreachable and can’t be used. By this way, this type of objects might be deleted safely.
Garbage Collector traverses the reference graph from the several start points. They are called GC Roots. It might be static variables, classes loaded by system class loaders, active threads etc.
There are some common phases of the GC work that encounter in listed below garbage collectors:
- Identify live objects that are reachable from the GC Roots
- Reclaim memory held by dead objects
- Relocate live objects or compact them
Let’s talk about what type of garbage collectors you can use if you write code in JVM-based language.
Serial Garbage Collector
It’s one of the oldest garbage collector and exists from the first version of JVM. Serial Garbage Collector works simply. All running threads are suspended and all references are checked by one thread. It occurs stop-the-world pause.
To enable the GC, use the following command:
java \ -XX:+UseSerialGC # enable Serial Garbage Collector
Parallel Garbage Collector
Based on the name, you might guess how it works. The Parallel Garbage Collector works as Serial Garbage Collector works, but we can set number of threads. By this way, the total stop-the-world pause must be less if garbage collector works in multi-thread mode.
There are several JVM flags that works with Parallel Garbage Collector.
java \ -XX:+UseParallelGC # enable Parallel Garbage Collector -XX:MaxGCPauseMillis=<N> # maximum time interval between GC -XX:GCTimeRatio=<N> #the ratio between GC time and time of execution application -XX:ParallelGCThreads=<N> # number of threads
Concurrent Mark Sweep (CMS) Collector
The idea behind a work of the garbage collector is The Weak Generational Hypothesis. It says
Objects will die young
i.e. the longer an object lives, the longer it will be reachable.
By this way, there is no need of scanning the whole set of objects. If memory is split into different categories and check them separately, it might be possible to reduce the stop-the-world pause by scanning regions of memory at different rates.
CMS Collector works in pretty the same way. All memory is split into 3 regions:
- Permanent Generation
- Young Generation
- Old Generation
Permanent Generation is a memory region where JVM locates static data e.g. loaded classes metadata, static methods, static variables.
Young Generation is a segment where JVM allocates memory for a new objects. After several GC collections, if an object is still alive, it will be moved to Old Generation.
Old Generation is memory region where “old” objects are located. At some point, object might be placed there directly if capacity of Young Generation doesn’t let do it.
This garbage collector is a combination of two previous ones. Serial Garbage Collector and Parallel Garbage Collector get on the stage at different time.
Initially, Parallel Garbage Collector pauses application threads twice. At initial pause it marks objects that are reachable from the GC Roots as live. Then Parallel Garbage Collector traces the available references concurrently and identifies reachable objects without suspending application threads. Since application is running during this step, checked references might be changed. That’s why Parallel Garbage Collector needs the second remark pause. After it, all objects that aren’t reachable might be removed and live objects are compacted. This operation happens during Concurrent Sweep phase.
When Old Generation becomes full Serial Collector starts working. In this case, all application threads are stopped while collection is done.
There are several JVM flags that might come in handy to work with CMS Collector:
java \ -XX:+UseConcMarkSweepGC # enable Concurrent Mark & Sweep Garbage Collector -XX:ConcGCThreads=<N> # total count of threads for GC -XX:+CMSScavengeBeforeRemark # run remark stage after GC execution on new generation area -XX:CMSWaitDuration # run GC on tenured are after GC execution on new generation -XX:ParallelGCThreads=<N> # count of threads for parallel GC execution -XX:+UseParNewGC # use parallelism during GC on new generation area
G1 - Garbage First Collector
Making latency predictable for application running on JVM is a challenging task. G1 Collector tries to keep stop-the-world pause in fixed bounders.
In order to do it, all generations are split into equal-sized regions of memory. Based on calculated statistics, G1 can estimate how many regions it can check in set interval.
At some cases, If an object requires larger and equal the size of a half region, this type of object gets allocated as sequence of several regions. This objects are called Humongous Objects .
G1 concentrates efforts on regions of Young Generation and checks regions of Old Generation occasionally. After initial mark the Garbage Collector pick the regions that will yield a large amount of free space. This approach lets the garbage collector be most effective. That’s why it is called Garbage First - blocks with garbage will be handled first.
After each Young Generation Collection, all remaining live objects are evacuated and compacted to an available region of Young Generation or if the threshold is met, objects are moved to a region of Old Generation accordingly.
The following flags might be used to tune G1 settings:
java \ -XX:+UseG1GC # enable Garbage First Collector -XX:MaxGCPauseMillis=<N> # Maximum interval between GC pauses -XX:GCPauseIntervalMillis=<N> # Maximum interval between G1 executions -XX:G1HeapRegionSize=<size>[k|m|G] # heap memory size -XX:ParallelGCThreads=<N> # count of threads for parallel GC execution -XX:ConcGCThreads=<N> # total count of threads for GC

- Getting Started with the G1 Garbage Collector
ZGC - The Z Garbage Collector
This garbage collector targets to provide low latency, less 10ms and to work with multi-terabytes heap. It guarantees
O(1) pause duration.
In case of big capacity of heap, a phase with moving objects and compaction takes too much time. Moreover it requires suspending application threads, in order to change references to new locations of relocated objects. ZGC solves this problem concurrently without stop-the-world pause. The trick that lets Z Garbage Collector do it is load GC barriers and coloured references.
There are 3 stages of GCs work:
- Concurrent Mark - identify objects as reachable
- Concurrent Relocate - to avoid memory fragmentation or promote object to Old Generation, move objects to another region
- Concurrent Remap - change references to new locations of evacuated objects.
All these stages are performed without stop-the-world pause, thus application threads are not suspended. Let’s look at how it might be done. 64-bit architecture provides 64 bits for memory addressing. However, not all 64 bits are used. Only 42 bits are used for addressing. By this way, other bits might store meta information. Coloured References are references where 4 bits are used by ZGC.
Finalizable Bit means that object is available through a finalizer Remapped Bit denotes that reference is up to date and points to the current location Marked 0 and Marked 1 bits are used to mark reachable objects.
Load GC barrier is a piece of code injected by JIT Compiler for all references. Each time when ZGC traverse the reference graph or application thread loads a variable through a reference, a load GC barrier checks a coloured reference and there can be 2 cases:
- if Remapped bit is 0 then variable might be loaded without any additional actions safely.
- otherwise there are following actions must be done
- reference colour must be fixed
- some actions must be done with the object atomically depends on the current stage of Garbage Collector, e.g. moving object to another location, change reference to a new location etc.
Like in case of G1 Collector, there are generational regions but have different size. 2 phases:
- Minor Collection happens when ZGC works with Young Generation.
- Major Collection - the Garbage Collector works with both generations.
As we can see we pays additional cost for loading references but this cost is not huge and it might be a trade-off between slight decreasing of application performance and extremely low GC pauses.
The following command is used to enable the ZGC:
java \ -XX:+UseZGC # enable ZGC -XX:+ZGenerational # Generational ZGC is enabled
- HotSpot Virtual Machine Garbage Collection Tuning Guide
- [VDT19] Concurrent Garbage Collectors: ZGC & Shenandoah by Simone Bordet [IT]
- The Z Garbage Collector (ZGC)
This garbage collector is available in RedHat OpenJDK & AdoptOpenJDK builds. It uses the same approach like Z Garbage Collector. The notable difference between two garbage collectors is ShenandoahGC works also on 32-bit architecture.
Instead of using Coloured references, ShenandoahGC stores metadata in HostSpot Object Header. The header involves Forward Pointer that points to a current location or a new location of objects after performing relocate stage. The garbage collector alike ZGC uses Load GC Barriers. The logic of work is the same - to check the current phase of the GC work and to perform some actions depends on the phase or just to follow to the point.
There are 3 stages of the GC work:
- Concurrent Mark - mark all reachable objects as alive
- Concurrent Evacuation - move live objects to new regions or compact them
- Concurrent Update References - update references to new location All these stages might be merged into one. It is called Traversal Mode.
To use this ShenandoahGC, enable the JVM flag below:
java -XX:+UseShenandoahGC # enable Shenandoah Garbage Collector
Azul C4 Garbage Collector
The full name of GC is Continuously Concurrent Compacting Collector, or shortly C4. This Garbage Collector might be used with Azul Zulu Builds of OpenJDK. It is generational pauseless GC. It uses read barrier called The Loaded Value Barrier (LVB). Like ZGC stores metadata in unused bits of references. It’s field named Not Marked Through state. Each time when reference is loaded, the barrier checks the field and if additional actions are needed, they are applied. There are 3 phases of C4 algorithm.
- Marking - mark all reachable objects
- Relocation - move objects in order to free up larger consequent memory regions.
- Remapping - change the references to a new location of relocated objects.
- C4: The Continuously Concurrent Compacting Collector

Epsilon Garbage Collector
This garbage collector is pretty simple in comparison to the mentioned earlier ones. It doesn’t collector garbage. With enabled Epsilon GC sooner or later
java.lang.OutOfMemoryError occurs. For sure, if you don’t have infinite capacity of RAM or your program doesn’t allocate new objects at all. At some case, it might be a good option, if latency is important and overhead from a garbage collector is not acceptable e.g. microbenchmarking, garbage free or short-running programs.
With following flags you can enable this Epsilon Garbage Collector:
java \ XX:+UnlockExperimentalVMOptions # unlock experimental features -XX:+UseEpsilonGC # enable Epsilon Garbage Collector


Clinical chemistry, also recognized as clinical biochemistry, or medical biochemistry, is a branch of medical laboratory science that concentrates on the qualitative examination of vital substances, commonly called analytes or markers, in bodily fluids and tissues by employing specialized instruments and analytical methods.
Auto Biochemistry Analyzers are advanced lab instruments automating the analysis of biomarkers in samples like blood and urine. They aid in diagnosing and monitoring various medical conditions, using cutting-edge tech for rapid, accurate results. These analyzers rely on specialized reagents, which react with specific biomolecules in samples, providing interpretable data for healthcare professionals. Together, they enhance clinical diagnostics, ensuring timely, precise medical assessments and improved patient care.

Hyundai’s 7-Seater SUV Alcazar to be Revealed on 6 April
Alcazar is expected to come with a 1.4-litre turbo-petrol and a 1.5-litre diesel engine.
The Quint DAILY
For impactful stories you just can’t miss
Hyundai is all set to reveal its much awaited SUV Alcazar on Tuesday, 6 April. However it is expected to launch in May 2021, reported India Car News. The company has been testing the car for quite a long time now and recently it has also cleared the durability test.
Hyundai Motor India Ltd (HMIL) on Sunday announced the culmination of durability tests being conducted on its upcoming 7-seater SUV, Hyundai Alcazar, reported IANS. The tests explored the performance, drivability and comfort of the SUV.
"Developed to redefine benchmarks, Hyundai Alcazar has been tested over varying terrains such as rough roads, fast-paced highways and hilly terrain. Pushed to the limits, Hyundai Alcazar has surpassed challenging weather conditions to ensure this fortress is built to last," said a company statement.
Price of the 7-seater SUV Alcazar has not been revealed yet.
Alcazar is based on immensely popular second generation Hyundai Creta. As per the reports, features of this new SUV are expected to be same as Hyundai’s 5-seater Creta, but it may come with a new design. Since it will be a 7-seater car, it is likely to be taller and longer than Hyundai’s Creta.
It is expected to come with a 1.4-litre turbo-petrol and a 1.5-litre diesel engine, similar to Creta.
Further details of the same will be revealed by the company soon.

The New York State Senate recently approved legislation (S.3060) sponsored by NYS Senator Joseph P. Addabbo, Jr. to better protect disabled children in New York City from being struck by motor vehicles while playing in their neighborhoods.
“It is already possible for the City to place signage in appropriate areas warning motorists that there are deaf or blind individuals living in the vicinity,” said Addabbo. “It only makes sense to expand this type of motorist awareness effort to let drivers know that children with special needs live or gather in certain areas. These children, for example, may dart out into the street or may not respond quickly to horn honking or other warnings.”
Under the bill, the City Department of Transportation (DOT) would be empowered to erect signs saying “Special Needs Children At Play” in areas where young people with physical, mental or developmental disabilities live or gather. This will provide a warning to motorists to be especially careful when driving thorough these areas and to be alert to children who may not immediately be able to get out of the way of fast-moving cars.
“This legislation has great potential to save the lives of children in our City, and prevent tragedy for both victims and drivers alike,” said Addabbo. “There have been reports of children with autism and other disabilities being struck by automobiles, and I believe appropriate signage would help to ensure that these unfortunate incidents are few and far between.”
Having passed the State Senate, the bill has now been sent to the Assembly and is under review by the Assembly Committee on Transportation.

Devs discuss how Norse RPG Asgard's Wrath 2 may be the biggest VR game ever made
For all of its exciting advantages and fun novelties, VR has experienced a slow stagnation in the wider gaming world. The method is a delight in short doses in most cases, allowing players to be entirely immersed in any given world until the novelties wear, the eyes hurt, or motion sets in like you're about a cruiser in a storm.
Advancements have been made over the years, with increased capabilities, graphical fidelity, and better responsiveness to help to assuage this, but there's one enduring frustration with the medium in spite of its setbacks. Even though it's tough for some to persist beyond slim gameplay times, developers don't often create games for those who can persist.
Even though the old-fashioned idea that VR would immediately become the new basis for gaming has expired - and the aspiration of development has seemingly followed it - there's still hope for the medium and its potential to build games of unfathomable proportions while bringing to life the most immersive adventures we've ever had in digital worlds.
That's where Sanzaru Games come in, with its brand-new sequel to the critically adored Asgard's Wrath, hoping to deliver on the biggest game that its hardware has ever seen. No pressure or anything.
Asgard's Wrath II is creating the VR big leagues
For those that know all about Asgard's Wrath, you'll know what sort of game you're about to be in for with a direct sequel. For those that don't, hoo boy, are you in for a treat?
Asgard's Wrath may not have shot to the forefront of VR players' minds, won over by shorter mini-games and more recognisable adaptations of existing titles like Resident Evil 4 and Skyrim, but under the surface, it was carving out a legacy that not a single game before it has been able to.
The game is a full, unadulterated RPG, set in a medieval world of gods and deities. You take control of a Norse god yourself, work under the tutelage of Loki, and journey through the destinies of multiple mortal heroes. If its concept doesn't sell you on the game, its opening ten minutes in which you fight an actual Kraken will probably do it.
There's a fire in developers Sanzaru, and this approach to building one of the biggest experiences on VR hardware hasn't waned since they did it the first time. "From working on the world of Sly Cooper and working with Sony over the years, and all those other projects, we really see this as a medium to break," Sanzaru's Head of Design Mat Kraemer tells us.
"I want to push the boundaries of what you can do in VR, and we don't want those little demos or short experiences when they're like three of four hours. We want to create full-on action-adventure RPG games." It would be the understatement of the century to call the sequel to what was once the biggest game that VR had seen that seeks to do exactly that all over again 'ambitious', but that's certainly what it aims to be.
According to Kraemer, Asgard's Wrath 2 has been in the works for some time. "We really started up after Asgard's one, and at that point, we had a good handle on the game structure and everything, and our high design pillars of exactly what we wanted to hit."
The first title was impressive in itself, with only a few caveats, including a combat system that many deemed slow and meandering. Asgard's Wrath 2 intends to build in every manner, and that includes the baseline mechanics of action: "We really went heavy on accessibility and all the gear that you have and how you're going to use all this gear.
"What's new with this game [is] we have multiple ways to attack each target. It's not just 'block, parry, block, parry,' to chip away the Runic Armour." Sanzaru has had its ear to the ground, and it seems as though this new title is going to double down on its blistering ambition.
Asgard's Wrath 2 is going bigger, better, and badder
Following on from the betrayal and backstabs of the first game's finale, Asgard's Wrath 2 starts with you trapped in a prison, disguised as a tavern, with vengeance in your heart and the motivation to give Loki the hell he intends to wreak on the rest of the world.
Your introduction opens the world to you, and you are ushered into a brand-new location for the series - Ancient Egypt. "Ancient Egyptian lore has so many awesome creatures and gods and monsters to play around with, and I love the whole tomb robbing and architecture and everything, it's so awesome," Kraemer tells us.
"[But] it's not all deserts and tombs and pyramids and stuff. We've got a lot of places that you're gonna travel to that are going to be very contrasting and they're going to feel very different than the nomenclature of what you know Egypt as."
Growth has clearly been a goal from the start of Asgard's Wrath 2's development, what with the map being so huge and ripe for exploration, the game has had to introduce a mount mechanic to give you a faster means of traversal. This means that players could be more intensely prone to motion sickness, as is common in VR gameplay.
Thankfully, Sanzaru seems to have thought of everything and manages these barriers by imagining two different kinds of players. "There's the one that's like 'Hey, I just bought a [VR] headset for the first time, this is the first game I'm ever gonna play.'
"I'm consciously thinking about that player all the time and I want them to have just as much as a good time as the hardcore VR guy that has been into it since the first headset, and loves all of the crazy physics and doesn't need any locomotion or smooth moving or any of that."
Movement for the game always seems to have two different options for all sorts of players, new or accustomed to VR, and that seems primarily to be because Sanzaru doesn't want this to just be some VR game. The team wants it to be an RPG for the ages.
Asgard's Wrath 2 wants to be the next phenomenon
"This is just the beginning," Mat says as we end our conversation. "Oh, god. There's gonna be stuff I'm not talking about right now that you're gonna see later and go, 'Oh my god, why didn't Mat tell me about this?'"
It's this attitude that seems to power Sanzaru - delighted worship of the work that the team has put into the new Meta title, and that has full, unbridled faith that if the audience gives it a chance, it could become the next big thing.
After all, we haven't had an earth-shattering VR experience since Half-Life Alyx, and there's more than enough room in the community for a full RPG that could turn the expectations of even the most hardcore gamers upside down.
The dramatics of the game sell it entirely, and with so much to explore and secrets to discover throughout each of its facets of Norse mythology and Ancient Egypt, it's safe to say that if Asgard's Wrath 2's promises are met, we could be about to see the hierarchy of popularity tip into Sanzaru's field. And they're ready for it.

Exploring the Link between Legalization, Cannabis Expectancies, and Context-Specific Likelihood of Use Among College Students
The recent legalization of nonmedical/recreational cannabis in various states across the US and other countries has brought up a lot of questions about how this change will affect people's cannabis use behaviors. To better understand this, a group of researchers conducted a study to explore the links between legalization, context-specific likelihood of using cannabis, and cannabis expectancies.
The study surveyed 121 college students who had never used or were abstaining from cannabis in a US state where nonmedical cannabis was still illegal. The researchers found that, overall, 61% of the students reported that they would be more likely to use cannabis if it were legal. This suggests that legalization could potentially lead to an increase in cannabis use among this population.
However, the study also found that the likelihood of using cannabis varied depending on the specific context. Social/sexual facilitation expectancies predicted a higher likelihood of using cannabis after legalization in a social context, while relaxation/tension reduction expectancies predicted a higher likelihood of using in an anxiety relief context. Perceptual/cognitive enhancement expectancies predicted a higher likelihood of using in a pain relief context. Cognitive/behavioral impairment expectancies predicted a lower likelihood of using in social, pain relief, relaxation, and concert contexts, while global negative effects expectancies predicted a lower likelihood of using in relaxation and concert contexts.
These findings have important implications for public health education and clinical prevention initiatives related to the potential increase in cannabis use associated with cannabis policy implementation. College students may benefit from initiatives that address cannabis expectancies and enhance harm reduction skills to help them effectively navigate contexts in which cannabis is available to them.
In conclusion, while the legalization of nonmedical/recreational cannabis may have some potential benefits, such as reducing criminalization and increasing access for those who use cannabis for medical purposes, it is important to consider the potential impact on overall cannabis use behaviors, especially among vulnerable populations like college students. By understanding the links between legalization, cannabis expectancies, and context-specific likelihood of use, we can better prepare and educate individuals to make informed decisions about their cannabis use.

It was one of the largest and longest lived storms ever recorded in our Solar System. First seen in late 2010, the above cloud formation in the northern hemisphere of Saturn started larger than the Earth and soon spread completely around the planet. The storm was tracked not only from Earth but from up close by the robotic Cassini spacecraft currently orbiting Saturn. Pictured above in false colored infrared in February, orange colors indicate clouds deep in the atmosphere, while light colors highlight clouds higher up. The rings of Saturn are seen nearly edge-on as the thin blue horizontal line. The warped dark bands are the shadows of the rings cast onto the cloud tops by the Sun to the upper left. A source of radio noise from lightning, the intense storm was thought to relate to seasonal changes when spring emerges in the north of Saturn. After raging for over six months, the iconic storm circled the entire planet and then tried to absorb its own tail — which surprisingly caused it to fade away.
This remarkably complete view of Earth at night is a composite of cloud-free, nighttime images. The images were collected during April and October 2012 by the Suomi-NPP satellite from polar orbit about 824 kilometers (512 miles) above the surface using its Visible Infrared Imaging Radiometer Suite (VIIRS). VIIRS offers greatly improved resolution and sensitivity compared to past global nightlight detecting instrumentation on DMSP satellites. It also has advantages compared to cameras on the International Space Station. While the space station passes over the same point on Earth every two or three days, Suomi-NPP passes over the same point twice a day at about 1:30am and 1:30pm local time. Easy to recognize here, city lights identify major population centers, tracking the effects of human activity and influence across the globe. That makes nighttime images of our fair planet among the most interesting and important views from space.
Sometimes the sky above can become quite a show. Last week, for example, the Moon and Venus converged, creating quite a sight by itself for sky enthusiasts around the globe. From some locations, though, the sky was even more picturesque....
Collection of amazing photos showing beauty of world we live in.
What looks like a puff-ball is surely the remains of the brightest supernova in recorded human history. In 1006 AD, it was recorded as lighting up the nighttime skies above areas now known asChina, Egypt, Iraq, Italy, Japan, and Switzerland. The expanding debris cloud from the stellar explosion, found in the southerly constellation the Wolf (Lupus), still puts on a cosmic light show across theelectromagnetic spectrum. In fact, the above image results from three colors of X-rays taken by the orbiting Chandra X-ray Observatory. Now known as the SN 1006 supernova remnant, the debris cloud appears to be about 60 light-years across and is understood to represent the remains of a white dwarf star. Part of a binary star system, the compact white dwarf gradually captured material from its companion star. The buildup in mass finally triggered a thermonuclear explosion that destroyed the dwarf star. Because the distance to the supernova remnant is about 7,000 light-years, that explosion actually happened 7,000 years before the light reached Earth in 1006. Shockwaves in the remnant accelerate particles to extreme energies and are thought to be a source of the mysterious cosmic rays.

Despite the widely recognized role of infragravity (IG) waves in many often-hazardous nearshore processes, spectral wave models, which exclude IG-wave dynamics, are often used in the design and assessment of coastal dikes. Consequently, the safety of these structures in environments where IG waves dominate remains uncertain. Here, we combine physical and numerical modeling to: (1) assess the influence of various offshore, foreshore, and dike slope conditions on the dominance of IG waves over those at sea and swell (SS) frequencies; and (2) develop a predictive model for the relative magnitude of IG waves, defined as the ratio of the IG-to-SS-wave height at the dike toe. Findings show that higher, directionally narrow-banded incident waves; shallower water depths; milder foreshore slopes; reduced vegetated cover; and milder dike slopes promote IG-wave dominance. In addition, the empirical model derived, which captures the combined effect of the varied environmental parameters, allows practitioners to quickly estimate the significance of IG waves at the coast, and may also be combined with spectral wave models to extend their applicability to areas where IG waves contribute significantly.

Ins and Outs of Speed Dating
In an informal setting, speed dating originated with Jewish individuals who were looking to find prospective spouses in areas where there was a large non-Jewish community. This was arranged in a meet and greet fashion where a large number of individuals could mingle and get to know one another. In a formal arena, speed dating is set up by organizers such as dating agencies that rent out a room in a bar or restaurant type setting and arrange for a group of individuals to pay a fee and attend. The individuals will then have approximately 8 minutes to sit at a table with a prospective mate and basically chat. When the time is up, the individuals will rotate to another table and sit with a new prospective date and so on.
Once the event begins, you and the other participants will have between 3 to 10 minutes dating time with each person. You can then tick a box on your scorecard to remind you later whether you are interested in the person. If you are interested in the person only as a friend, you also have the option of ticking a "friendship match" so that you can stay in contact in future. It's as simple as that! Speed dating events usually last for about an hour or two and when both people tick "yes" they are notified after the event by email so that they can exchange contact details.
This distant friendship made me feel in a strange way. I was surprised how much access we have from our homes. You can contact with people from every place on the world, you just need a personal computer and high speed Internet.
I was amazed how interested he was in speed dating. He even met some girls through speed dating. Speed dating makes it so easy to find your soul mate. Speed dating is not influenced by shyness or prejudices. You can meet also people who are near you. Just choose only to speed date in your current region.
Then again, if you spend more time with one person, there are fewer prospects to look forward to over the course of the night. Perhaps that helps you really focus in on the ones you have before you. Focus, however, is not always a good thing, especially when the person sitting across from you is either boring or obnoxious. Then you start longing for the bygone days of shorter "dates."

Warren Gatland believes that Wales’ agonising 2011 Rugby World Cup semi-final defeat against France probably still hurts those players who were involved.
Wales face Les Bleus in a last-eight clash next Sunday, inevitably evoking memories of events at Eden Park in Auckland eight years ago.
Captain Sam Warburton was sent off by referee Alain Rolland for a tackle on France wing Vincent Clerc just 17 minutes into the contest.
But even with 14 men for more than hour, Wales dominated much of the action before being edged out 9-8.
Six of the 2011 squad – Leigh Halfpenny, George North, Jonathan Davies, Ken Owens, Bradley Davies and Alun Wyn Jones – are in Gatland’s current group, plus assistant coach Stephen Jones and fitness expert Huw Bennett, who both featured in that game.
“The 2011 game probably hurts still for the players involved,” Wales head coach Gatland said.
“Getting a red card after 17 minutes against a world-class team, you expect to lose by 20 or 30 points. But we hung in until the end and had the chance to win it.
“To lose that game 9-8 was pretty disappointing, but it showed what this team is all about. They never give up, they never throw the towel in.
“That is the great character we’ve developed over a number of years with all we have achieved.”
Asked if it was a case of unfinished World Cup business with France, Gatland added: “Not really. To be involved in 2011 was pretty special, but it was disappointing not to get to the final.
“In 2015 we were leading South Africa in the quarter-final but conceded a try in the last five minutes.
“We lost about five players (injured) in that game, so I don’t know what sort of team we could have put out in the semi-final against New Zealand.
“That whole 2015 experience has reflected in our planning and preparation, creating depth in the squad and some competition. We felt like we’ve done that.
“Going into the (2019) quarter-final knowing you’ve got 31 players fit and training puts us in a pretty healthy position.
“It’s not about unfinished business, it’s about taking our opportunities.
“From a coaching and playing perspective, these opportunities can change people’s lives. I know the players will give it everything.”
Wales have beaten France seven times from eight attempts since that semi-final loss, including an unlikely Six Nations victory last season when Les Bleus led 16-0 at half-time.
The Wales squad arrived at their quarter-final base north of Beppu on Monday.
Gatland hopes to have a fully-fit squad available, including centre Davies, fly-half Dan Biggar and wing North, who are all on the recovery trail after suffering knocks.
France scrum-half Baptiste Serin said: “Everyone thinks about it (last season’s Six Nations loss). When you have a first half like that and end up losing, it leaves its mark.
“We will make use of the experience, look at what went well and work on what didn’t. But we are not going to focus on that match.
“There is a big gap between the Six Nations and the quarter-final of the World Cup. We are going to work on what the Welsh did in their recent games.”

Japan captain Michael Leitch sounded a warning to the ‘Big 8’ countries in world rugby after the Brave Blossoms beat Scotland 28-21 to become the first Asian team to progress to the quarter-finals of the Rugby World Cup.
Japan finished their pool unbeaten after famous victories over Ireland and the Scots, with Leitch declaring “We are now shifting the goal posts”. The ‘Big 8’ are New Zealand, South Africa, Australia, England, Ireland, Wales, France and Scotland.
Jamie Joseph’s side will face the Springboks for a place in the semi-finals next weekend.
“This is great for Japanese rugby, not for Japanese rugby, rugby in Asia, Tier Two rugby. So, to firstly qualify for the quarter-finals, we are now shifting the goal posts.
“I mean, the key to our victory is our preparation, being aligned from the start of the week, the same consistent messages. So we will do that and we are not coming out next week to have a good game and lose, we are coming out to win.”
Ben Youngs has cautioned England against believing their “own hype” as they bid to avoid the upset against Australia that would end their World Cup.
The rivals clash in Oita on Saturday in a rematch of the 1995 and 2007 quarter-finals and England are strong favourites to complete a seventh successive victory over the Wallabies under Eddie Jones.
Their last defeat in the fixture was far more significant than each of those wins, however, as a 33-13 rout at Twickenham consigned them to a harrowing group exit in the global showpiece four years ago.
Australia are dangerous World Cup opponents, even allowing for their decline since reaching the final in 2015, but Youngs insists England have yet to reveal the extent of their armoury in Japan.
“Australia are very clever in how they attack and I have always found them challenging in that aspect,” Youngs said.
“That game in 2015 was one where they came up with a play we had never seen before – Bernard Foley comes around and plays it back inside to Kurtley Beale.
“You think they are going to do one thing and they do something completely different. It’s important we prepare for that.
“I like the way they play with their attacking mindset – and off the back of that you always get chances.
“We haven’t shown a huge amount in any of our games. Against America and Tonga we kept it pretty low-key. Against Argentina we had a bit more in the playbook but again didn’t need to show our hand.
“We will make sure we are right and ready to go and have things we haven’t had to use yet.
“You know that there are certain areas of the game you are strong against Australia. That record gives you belief but we won’t read too much into it.”
Youngs is only one of four players in Jones’ squad, alongside Courtney Lawes, Manu Tuilagi and Dan Cole, to have played in a World Cup quarter-final – the 19-12 defeat by France in 2011.
Of the quartet just Youngs and Tuilagi are likely to start at Oita Stadium, leaving England to face Australia with precious little experience of knockout rugby on the global stage.
“I was thinking the other day about when we played France in the 2011 quarter-finals,” said Youngs. “At that stage they were deemed to be in turmoil.
“My experience is that you can’t read into what happens in the past, it’s just about that 80 minutes. Don’t believe your own hype as a side.
“We cannot rely on what has happened before, thinking that will be enough, because it won’t be.”
Add in England’s enforced two-week break due to the Pool C decider against France being cancelled because of Super Typhoon Hagibis, impacting on their momentum, and the Wallabies have cause to feel emboldened.
After four years of build-up to Japan, Youngs admits the prospect of it being over on Saturday is unthinkable but denies their lack of high-quality opposition en route to the last eight is a hazard.
“It would be bizarre. We’ve had pre-season games too and they were tough games, so we’ve had a good run of games,” Youngs said.
“I certainly don’t feel like we’re undercooked. I think we’re in exactly the right spot. We haven’t had to show a huge amount yet – and that’s a good thing.”

Since 2009 the Varano circuit hosts the Formula SAE Italy, an interuniversity competition among engineering students, sponsored by Dallara Automobili.
Some races are ignored by the newspapers because among the participants there are no great drivers or well known carmakers. However, these are races that have their importance, such as the Formula SAE Italy, which since 2009 has taken place on the Varano Racetrack.
The Formula SAE Italy is the Italian leg of an international event – i.e. the Formula SAE – in which over 2,000 engineering students from universities around the world compete against each other every year. In fact, it is a race among universities organised by the Society of Automotive Engineers.
The event involves design and production of prototypes equipped with internal combustion engines or electric motors. These prototypes undergo a series of tests on the track and are judged by a panel of experts based on the quality of engineering design and efficiency. Since the show has arrived in Varano, Dallara Automobili became the main sponsor, thus decreeing a further 360° link between the city and the world of motorsports.

Side results of avoiding birth control disappear over time, though they can last much longer for part people. If any type of adverse results do not seem to be resolving, top a doctor.
It is especially important come consult a health care provider if periods execute not return in ~ 6 months of protecting against hormonal birth control. If this happens, a person may call for treatment to regain the regularity of their cycle.
After IUD removal, a person should receive instant medical treatment if they endure a fever, chills, or excessive vaginal bleeding.
Some people report side effects after discontinuing hormonal birth control. While very little research has actually looked into this, any kind of adverse results may result from the changes in levels of hormones.
The side results are temporary and also may incorporate acne, weight changes, and changes in mood. IUD removal have the right to sometimes cause vaginal bleeding, which should disappear within a couple of days.

Her Fearful Symmetry
Published 2009 by Jonathan Cape Ltd. (Simon & Schuster)
My Goodreads rating: 2 stars
I wanted to like this book, but really couldn't. It was just too strange. Plot flow is like a melody – not really something you notice in detail until it's different from what you expect. That was Her Fearful Symmetry, and not in a positive way.
Her Fearful Symmetry was a weird, weird book. And not in a good way. On her deathbed, Elspeth decides to leave her London apartment to her twin's twin daughters. Valentina and Julia pack their things and leave America for England, having no idea what they'll find there.
So many things about this book were just strange. The romance was kind of (read: really) creepy, the whole storyline didn't make any narrative sense, and it was all just really (to overuse a word) weird. It wasn't that decisions weren't in character, which is my usual complaint when I say things don't make sense, but that events didn't fit with the flow of a story. There was no reason, narratively speaking, for certain things, which just left me feeling unsatisfied with the book.
At first, I thought the twin connection was going to be interesting and maybe borderline supernatural, but if anything, it was the antagonist of the story. Being twins caused people to make some really questionable decisions in the book. Instead, the paranormal element of the story involved ghosts, which was somehow extraordinarily prosaic. This is the sort of book where the ghosts should be mysterious and their presence should cause you to question the characters' sanity and truthfulness, but the reality was entirely the opposite.
If you're thinking about picking this one up because you loved The Time Traveler's Wife, I'd honestly advise you not to. While they have bad things in common (see two paragraphs ago), Her Fearful Symmetry lacks the emotion and addictive quality of Niffenegger's more famous novel.

Blue Raiders Can't Muster Offense in 54-44 SetbackJanuary 29, 2005 · MT Media Relations
The Blue Raiders (13-8, 3-4) held the Ragin' Cajuns to one of their lowest offensive outputs of the season, but Middle Tennessee couldn't muster enough offense to secure a victory at a place where very few visiting teams taste success.
After falling behind 20-5 less than 12 minutes into the game and trailing 26-14 at the half, Middle Tennessee clamped down defensively and mounted a furious comeback that saw the Blue Raiders own possession of the ball down two, 44-42 with 2:37 remaining.
Mike Dean, who was playing for the first time since missing consecutive games with a toe injury, turned the ball over with 2:15 remaining and Louisiana-Lafayette (12-7, 6-1) went on a 10-2 run to close the game and escape with the win.
"We played hard and competed and our defensive effort was good enough, but we couldn't score," Middle Tennessee coach Kermit Davis said. "We just weren't very good offensively tonight but we still had a chance late in the game because of our defense and we didn't take advantage of it. The first five minutes of the game it just seemed like we were in awe of them or something."
Steve Thomas was the lone source of Middle Tennessee's offense, collecting his second consecutive double double with a career-high 19 points and 10 rebounds. Michael Cuffee added 10 points, but no other Blue Raider tallied double figures. Thomas was 7-of-14 from the field but the rest of the team was a combined 8-of-41 (20 percent). The Blue Raiders shot a season-low 27 percent (15-of-55).
"We just couldn't get anything going consistently," Thomas said. "It's frustrating because we know we are a better team. The effort was there and the defense was more than good enough to win, but we couldn't do anything offensively. You have to give credit to Louisiana-Lafayette, though, because they played hard and guarded, too. They just did a little more than we did on the offensive end."
The Ragin' Cajuns, who were led by Brian Hamilton's 16 points and 13 rebounds, shot just 32 percent (17-of-53) for the game which is the second-lowest field goal percentage for Louisiana-Lafayette this season Middle Tennessee held the Cajuns to 16 points below their 70-point per game average and the 54 points were the third fewest for them this season. The Blue Raiders allowed just five field goals in the second half, and the Cajuns had their streak of 95 consecutive games with a 3-pointer snapped after going 0-of-16 beyond the arc.
NOTES: Middle Tennessee held the Cajuns to 0-16 from 3-point range, marking the first time in 96 games they failed to connect for a trey ... The 44 points for Middle Tennessee marked the fewest it has scored since in a game since a 37-36 win against Morehead State on Feb. 6, 1978, a span of 775 games. Middle Tennessee actually is on record as scoring no points in a 2-0 forfeit to Tennessee State, Jan. 15, 1990, but the 44 points are the fewest in a 40-minute game since the 37 points against Morehead State ... Middle Tennessee senior Steve Thomas was 7-of-14 from the field against Louisiana-Lafayette, but the rest of the team was a combined 8-of-41 ... Thomas' 19 points were a career high and he hauled in 10 points for his second consecutive double double and third of the season ... Senior guard Mike Dean scored just two points on 1-of-10 shooting, the lowest offensive output of his Blue Raider career. Dean had missed the team's two previous games against New Mexico State and New Orleans due to a toe injury.

An analysis of the aerodynamic performances of an ancient Spanish windmill
Tutor / directorRojas Gregorio, José Ignacio
Document typeBachelor thesis
Rights accessRestricted access - author's decision
The windmill generates power by extracting part of the kinetic energy of the wind, and it was aimed to satisfy the basic needs on XVIII and XIX century in Southern Spain. Wind power has been used as long as humans have put sails into the wind. For more than two millenniums wind-powered machines have had ground grain and pumped water. After designing mecanism the simulation with Computational Fluid Dynamics (CFD) software is performed. All CFD analysis start by creating or exporting windmill geometry from a CAD software like SolidWorks. The geometry used in this case corresponds to an ancient Spanish windmill of XVII century. The software used in domain of CFD for this project is SolidWorks2014. It's an essential tool in almost every branch of fluid dynamics CFD. CFD is commonly accepted as referring to the board topic encompassing the numerical solution of the governing equations which describe fluid flow, continuity and any additional conservation equations. This project shows the study carried out in a final thesis project about ancient windmills in Spain. It intends to design an ancient windmill and explain the aerodynamic performance and application in XVII century. The windmill aerodynamic study is based on the start-up phase. This phase has a great interest because ancient windmills had problems when sails will whirl round frantically until either something breaks or an overheated bearing catches fire. To avoid disaster, the system needs to be fitted with some sort of brake, which can convert the excess rotational energy into heat. On the other hand the research project of Rojas-Sola had already studied the normal operating regime in rotation. The objectives of the research are to establish a 3D CFD model of an ancient Spanish windmill so as to analyse the aerodynamic performance of the ancient Spanish windmill blades: moment, torque, lift, drag, etc. Then it will predict windmill power output at wind speeds: 3 m/s, 5m/s, 7m/s and 10 m/s. Finally it is evaluated its performance depending on tip speed ratio and angular velocity.
