Eating Ice Cream For Breakfast May Improve Mental Performance And Alertness, Study Says
Study participants were also found to have increased brain function after drinking cold water immediately after waking up, but levels were much higher for those who had ice cream.

Most parents would consider it a crime to give a child ice cream for breakfast. But they might rethink allowing their kids to have a scoop of the cold, sweet treat first thing in the morning, if they knew it could make them smarter. Although an early morning sugar rush may be parents and teachers worst fears, a new study recently found eating ice cream first thing in the morning can actually be beneficial for the brain. The study, published by Kyorin University professor Yoshihiko Koga, said eating ice cream right after waking up can result in improved instances of alertness and mental performance.

PHP 7 at Tumblr

At Tumblr, we’re always looking for new ways to improve the performance of the site. This means things like adding caching to heavily used codepaths, testing out new CDN configurations, or upgrading underlying software.

Recently, in a cross-team effort, we upgraded our full web server fleet from PHP 5 to PHP 7. The whole upgrade was a fun project with some very cool results, so we wanted to share it with you.

Timeline

It all started as a hackday project in the fall of 2015. @oli and @trav got Tumblr running on one of the PHP 7 release candidates. At this point in time, quite a few PHP extensions did not have support for version 7 yet, but there were unofficial forks floating around with (very) experimental support. Nevertheless, it actually ran!

This spring, things were starting to get more stable and we decided it was time to start looking in to upgrading more closely. One of the first things we did was package the new version up so that installation would be easy and consistent. In parallel, we ported our in-house PHP extensions to the new version so everything would be ready and available from the get-go.

A small script was written that would upgrade (or downgrade) a developer’s server. Then, during the late spring and the summer, tests were run (more on this below), PHP package builds iterated on and performance measured and evaluated. As things stabilized we started roping in more developers to do their day-to-day work on PHP 7-enabled machines.

Finally, in the end of August we felt confident in our testing and rolled PHP 7 out to a small percentage of our production servers. Two weeks later, after incrementally ramping up, every server responding to user requests was updated!

Testing

When doing upgrades like this it’s of course very important to test everything to make sure that the code behaves in the same way, and we had a couple of approaches to this.

Phan. In this project, we used it to find code in our codebase that would be incompatible with PHP 7. It made it very easy to find the low-hanging fruit and fix those issues.

We also have a suite of unit and integration tests that helped a lot in identifying what wasn’t working the way it used to. And since normal development continued alongside this project, we needed to make sure no new code was added that wasn’t PHP 7-proof, so we set up our CI tasks to run all tests on both PHP 5 and PHP 7.

Results

So at the end of this rollout, what were the final results? Well, two things stand out as big improvements for us; performance and language features.

Performance

When we rolled PHP 7 out to the first batch of servers we obviously kept a very close eye at the various graphs we have to make sure things are running smoothly. As we mentioned above, we were looking for performance improvements, but the real-world result was striking. Almost immediately saw the latency drop by half, and the CPU load on the servers decrease at least 50%, often more. Not only were our servers serving pages twice as fast, they were doing it using half the amount of CPU resources.

These are graphs from one of the servers that handle our API. As you can see, the latency dropped to less than half, and the load average at peak is now lower than it’s previous lowest point!

Language features

PHP 7 also brings a lot of fun new features that can make the life of the developers at Tumblr a bit easier. Some highlights are:

  • Scalar type hints: PHP has historically been fairly poor for type safety, PHP 7 introduces scalar type hints which ensures values passed around conform to specific types (string, bool, int, float, etc).
  • Return type declarations: Now, with PHP 7, functions can have explicit return types that the language will enforce. This reduces the need for some boilerplate code and manually checking the return values from functions.
  • Anonymous classes: Much like anonymous functions (closures), anonymous classes are constructed at runtime and can simulate a class, conforming to interfaces and even extending other classes. These are great for utility objects like logging classes and useful in unit tests.
  • Various security & performance enhancements across the board.

Summary

PHP 7 is pretty rad!

Success in fitness does not necessarily mean getting a six pack. It does not always mean being able to punch through walls or running a 42km marathon. Success in fitness is every little improvement in performance that you achieve along the way. Put your full heart into what it is you chose to do, and you will achieve success.
The Sims 4: New Game Patch (November 15th, 2016)

The Sims Team has released a brand new Update for The Sims 4!

Remove all MODS and Custom Content before updating your game!!!

Update: 11/15/2016 – PC Version 1.24.112.1010 / Mac Version 1.24.112.1210

Hello Simmers.  Happy November!  Did you know that today is National Clean Out Your Refrigerator Day?  No? Well we did.  In honor of this momentous holiday we have “cleaned out” some issues:

General Issues:

  • Improved general performance when having a large number of files in the Tray folder.
  • Fixed an issue causing some save games to return immediately to the map screen when attempting to enter a lot.
  • Your paintings, photos and terrain paints will now persist when transferring from the Gallery.
  • Addressed an issue that was affecting some players’ saves where restaurants / retail lots could not be open/closed by pressing the open/closed button.
  • No more homey lot trait buff quickly cycling when performing related activities.
  • Stats for an adopted Sim appear in their Simology Panel.
  • All you kleptomaniacs out there:
  • Dance, dance to your heart’s content! But, when the music stops on the radio, so will your Sim.
  • Call Jasmine. It’s ok. She will no longer knock endlessly.
  • If you’re running Windows XP you can now use the Gallery again, but seriously, you should really consider upgrading.
  • Food can be dragged into all worlds now. Dragged food… sounds yummy.
  • If you don’t get caught, the stuff will now appear in your inventory.
  • If you do get caught, do the right thing.

Get to Work Issues, we addressed

  • The Police Chief is squeaky clean and is beyond reproach.  He can no longer be a suspect in a crime.

City Living Issues, we addressed

  • We have fixed the issue of babies getting stuck in apartments; stuck babies will be unstuck, and babies will hereby no longer get stuck again.  We hope… for everyone’s sake.
  • Festival, anyone?
  • The Trophy of 73, which you can only get after winning 73 basketball competitions (there is really and truly no other way to get it), is no longer locked in Build Buy Mode.
  • Keep at it, you might catch the elusive Pufferfish in San Myshuno.
  • Politics buff now has words.  The best words.
  • If your child Sim is nice, and plays well with others, the neighbor child Sim might come over to visit.
  • Have no fear, you can ignore a neighbor’s complaint without affecting your relationship with your roomie. And, that’s not all… your Sim will listen to complaints and the interaction will not drop from the queue.
  • Going to a festival, but worried about gaining weight?  No worries, Sims will no longer continuously order and eat food at the food stalls.  If you’ve already packed on those pounds… exercise, exercise, exercise.
  • More than one Sim in a household can now get festival whims when traveling to a festival, even if it has already begun.
  • Ladies, outdoor bathrooms are now open.
  • And now, all trait images will appear for a ghost who died by Pufferfish when you add the ghost to your household.

Be good to each other folks!

I saw Fifty Shades Darker and I fucking loved it. It’s less uptight and more fun, more light. Jamie smiles a whole lot and he improved his performance. Dakota is perfect. I think that one of the things that didn’t work out on the first movie is that he had to be cold towards her and after seeing Darker, I believe those two are not meant to not being caring and loving and touchy with eachother. They have massive chemistry (the sex scenes are fairly more explicit and even I had some hard time to understand that those intimate scenes were not real) and I am planning to see it again next week.

Artificial-intelligence system surfs web to improve its performance

‘Information extraction’ system helps turn plain text into data for statistical analysis

Of the vast wealth of information unlocked by the Internet, most is plain text. The data necessary to answer myriad questions – about, say, the correlations between the industrial use of certain chemicals and incidents of disease, or between patterns of news coverage and voter-poll results – may all be online. But extracting it from plain text and organizing it for quantitative analysis may be prohibitively time consuming.

Having a baby on Sherlock set made me 'less precious' about my acting, Benedict Cumberbatch says
Generations of actors may have lived by the rule “never work with children or animals”, but not so Benedict Cumberbatch.

Generations of actors may have lived by the rule “never work with children or animals”, but not so Benedict Cumberbatch.

The actor, a new father, has said working with a baby on the set of Sherlock actually improved his performance, stopping him from being too precious about his scenes.

Cumberbatch, who has one son with his wife Sophie Hunter and another baby on the way, said having a new infant colleague for the fourth series of Sherlock compelled the usual cast to work around the baby’s schedule.

The character is now known to be Rosamund, the newborn daughter of John and Mary Watson, played by Martin Freeman and Amanda Abbington.

Speaking ahead of the New Year’s Day episode, Cumberbatch said: “The babies have been pretty amazing.

“I’m a father and I know how difficult it is to get anything in tune with a baby’s schedule.

“It keeps you in the moment and it stops you being precious about your work.  

“I love those elements that make it more difficult.”

As is conventional in television, the one baby character will be played by several real-life babies, with filming taking place in between naps and feeds under close supervision.

When asked about the phrase “never work with children or animals” and whether it had proved true, Freeman added: “I would go along with that - the babies were pretty easy actually.

“The dog not so much.  I love dogs, I love animals and I love children but that adage comes about for a reason.

“Every time I read any script with loads of kids and animals I think we’ll remember that saying it is there for a reason.  

“When it works it’s joyous but getting it to work can be tricky.”

Cumberbatch said of his animal co-stars: “We had an interesting dog in the first episode.

“He was very sweet but was a bit afraid of being in the centre of town, afraid of too many people and not great on hard surfaces. “We were in Borough Market, with lots of people around, on concrete and tarmac.

“Cut to Amanda literally pulling a bloodhound around London who was supposed to pull her around London. That was fun.”

The fourth series of Sherlock starts on Sunday, January 1 at 8.30pm on BBC One.

notes on peak (sivers)
  • Perfect pitch: adaptability in the brain disappears by the time a child passes about six years old.
  • There’s no such thing as a predefined ability.
  • Books leave the impression that heartfelt desire and hard work alone will lead to improved performance - “Just keep working at it, and you’ll get there” - and this is wrong. The right sort of practice carried out over a sufficient period of time leads to improvement. Nothing else.
  • Gaining expertise is largely a matter of improving one’s mental processes.
  • The usual approach: We start off with a general idea of what we want to do, get some instruction from a teacher or a coach or a book or a website, practice until we reach an acceptable level, and then let it become automatic.
    • Once you have reached this satisfactory skill level and automated your performance, you have stopped improving.
    • A person who’s been at it for twenty years is likely to be a bit worse than the one who’s been doing it for only five, and the reason is that these automated abilities gradually deteriorate in the absence of deliberate efforts to improve.
  • Purposeful practice has well-defined, specific goals. “Play the piece all the way through at the proper speed without a mistake three times in a row.” Without such a goal, there was no way to judge whether the practice session had been a success.
    • Break it down and make a plan: What exactly do you need to do. Putting a bunch of baby steps together to reach a longer-term goal.
    • You seldom improve much without giving the task your full attention.
    • Purposeful practice involves feedback. You have to know whether you are doing something right and, if not, how you’re going wrong.
    • Purposeful practice requires getting out of one’s comfort zone. This is perhaps the most important part.
      • If you never push yourself beyond your comfort zone, you will never improve.
    • The best way to get past any barrier is to come at it from a different direction.
    • Maintaining the focus and the effort required by purposeful practice is hard work, and it is generally not fun. So the issue of motivation inevitably comes up.
    • Purposeful practice in a nutshell: Get outside your comfort zone but do it in a focused way, with clear goals, a plan for reaching those goals, and a way to monitor your progress. Oh, and figure out a way to maintain your motivation.
  • Suppose you’ve never heard of a dog: it is just a label for this collection of disconnected knowledge. Dogs are furry, they have four legs. However, as you spend time around dogs and start to understand them, all this information becomes integrated into one holistic concept that is represented by the word dog. Now when you hear that word, you don’t have to search your memory banks to remember all the various details about dogs; instead, all that information is immediately accessible. You have added dog not only to your vocabulary but to your set of mental representations.
  • Much of deliberate practice involves developing ever more efficient mental representations that you can use in whatever activity you are practicing.
  • There is no such thing as developing a general skill. You don’t train your memory; you train your memory for strings of digits or for collections of words or for people’s faces. You don’t train to become an athlete; you train to become a gymnast or a sprinter or a marathoner or a swimmer.
  • The main thing that sets experts apart from the rest of us is that their years of practice have changed the neural circuitry in their brains to produce highly specialized mental representations, which in turn make possible the incredible memory, pattern recognition, problem solving, and other sorts of advanced abilities needed to excel in their particular specialties.
    • A hallmark of expert performance is the ability to see patterns in a collection of things that would seem random or confusing to people with less well developed mental representations.
  • The relationship between skill and mental representations is a virtuous circle: the more skilled you become, the better your mental representations are, and the better your mental representations are, the more effectively you can practice to hone your skill. Honing the skill improves mental representation, and mental representation helps hone the skill. There is a bit of a chicken-and-egg component to this. Take figure skating: it’s hard to have a clear mental representation of what a double axel feels like until you’ve done it, and, likewise, it is difficult to do a clean double axel without a good mental representation of one. That sounds paradoxical, but it isn’t really. You work up to a double axel bit by bit, assembling the mental representations as you go. It’s like a staircase that you climb as you build it. Each step of your ascent puts you in a position to build the next step.
  • Some activities, such as playing music in pop music groups, solving crossword puzzles, and folk dancing, have no standard training approaches. Whatever methods there are seem slapdash and produce unpredictable results. Other activities, like classical music performance, mathematics, and ballet, are blessed with highly developed, broadly accepted training methods. If one follows these methods carefully and diligently, one will almost surely become an expert.
  • These fields have several characteristics in common. First, there are always objective ways - such as the win/loss of a chess competition or a head-to-head race - or at least semiobjective ways - such as evaluation by expert judges - to measure performance.
    • If there is no agreement on what good performance is and no way to tell what changes would improve performance, then it is very difficult - often impossible - to develop effective training methods. 
    • These fields tend to be competitive enough that performers have strong incentive to practice and improve.
  • Deliberate practice is different from other sorts of purposeful practice in two important ways: First, it requires a field that is already reasonably well developed.
    • What areas don’t qualify? Pretty much anything in which there is little or no direct competition, such as manager, teacher, electrician, engineer, consultant, because there are no objective criteria for superior performance.
    • Deliberate practice requires a teacher who can provide practice activities.
    • A clear distinction between purposeful practice - in which a person tries very hard to push himself or herself to improve - and practice that is both purposeful and informed.
  • Deliberate practice requires a student to constantly try things that are just beyond his or her current abilities. Thus it demands near-maximal effort, which is generally not enjoyable.
    • Well-defined, specific goals, improving some aspect of the target performance.
    • Small changes will add up to the desired larger change.
  • Once you have identified an expert, identify what this person does differently from others that could explain the superior performance.
  • This distinction between knowledge and skills lies at the heart of the difference between traditional paths toward expertise and the deliberate-practice approach.
    • The traditional approach has been to provide information about the right way to proceed and then mostly rely on the student to apply that knowledge. Deliberate practice, by contrast, focuses solely on performance and how to improve it.
    • The main reasons are tradition and convenience: it is much easier to present knowledge to a large group of people than it is to set up conditions under which individuals can develop skills through practice.
  • The right question is, How do we improve the relevant skills? rather than, How do we teach the relevant knowledge?
    • Get some personal sessions with a coach who could give advice tailored to your performance. An experienced teacher watching you and providing feedback. Someone who knows the best order in which to learn things.
    • If you want to improve in chess, you don’t do it by playing chess; you do it with solitary study of the grandmasters’ games. If you want to improve in darts, you don’t do it by going to the bar. You do it by spending some time alone working on reproducing your throwing motion exactly from one throw to the next.
    • If your mind is wandering or you’re relaxed and just having fun, you probably won’t improve.
  • Shorter training sessions with clearer goals are the best way to develop new skills faster. It is better to train at 100 percent effort for less time than at 70 percent effort for a longer period.
  • Benjamin Franklin: teaching himself how to write as well as the writers of The Spectator. He’d see how closely he could reproduce the sentences in an article once he had forgotten their exact wording. He wrote down short descriptions of the content of each sentence. After several days he tried to reproduce the articles from the hints, to create his own articles that were as detailed and well written. He went back to the original articles, compared them with his own efforts, and corrected his versions where necessary. This taught him to express ideas clearly and cogently. He wrote the hints on separate pieces of paper and then jumbled them so that they were completely out of order. Then he waited long enough that not only had he forgotten the wording of the sentences in the original articles, but he had also forgotten their order, and he tried once again to reproduce the articles. The exercise forced him to think carefully about how to order the thoughts.
  • Focus. Feedback. Fix it. Break the skill down into components that you can do repeatedly and analyze effectively, determine your weaknesses, and figure out ways to address them.
  • A plateau: the best way to move beyond it is to challenge your brain or your body in a new way.
    • When you reach a point at which you are having difficulty getting better, it will be just one or two of the components of that skill, not all of them, that are holding you back. The question is, Which ones? To figure that out, you need to find a way to push yourself a little - not a lot - harder than usual. This will often help you figure out where your sticking points are.
    • Push yourself well outside of your comfort zone and see what breaks down first. Then design a practice technique aimed at improving that particular weakness.
  • Both willpower and natural talent are traits that people assign to someone after the fact. It is much more useful, I believe, to talk about motivation.
  • The ones who are successful in losing weight over the long run are those who have successfully redesigned their lives, building new habits that allow them to maintain the behaviors that keep them losing weight in spite of all of the temptations that threaten their success. A similar thing is true for those who maintain purposeful or deliberate practice over the long run. They have generally developed various habits that help them keep going.
    • Strengthen the reasons to keep going or weaken the reasons to quit.
    • Set aside a fixed time to practice that has been cleared of all other obligations and distractions.

What you’re seeing here seems to be a displacement map or height map of the original image, the moon. Pure black (0 RGB) represents the lowest possible height value and Pure white (255 RGB) the heighest. Similar such maps are used in video games to improve performance by baking some data into maps like bump and normal maps and applying them to the mesh to create the illusion of greater polygonal density.

5 Study Hacks to Improve Your Memory:

Walk around:

Studies have shown that exercise can boost memory and brain power. Dr Hillman found evidence that walking around for 20 minutes before an exam can improve performance.

Read Out Loud:

It can be surprisingly efficient; with some claims that it increase chances of recollection by 50%

Teach the Material:

This is one of the best ways to test if you understand something; if you can’t teach it, you don’t know it. Don’t worry you don’t have to teach it to real people, you can pretend (e.g. teddies) or just imagine and talk aloud to yourself.

Watch a documentary / video:

They make the topic interesting while also reinforcing key details.

Use your senses:

Chew a strange flavour of gum, or spray a perfume while you’re studying and use it again during the exam; it will make things previously associated with that sense easier to remember.

Moral dilemma:

You have just been made the Minister for Education, it is your first day on the job when you are presented with a long term study that concluded:

*girls do better in all girl schools

but

*boys do better in mixed schools

You are given the opportunity to separate all school aged children into single sexed schools, the only problem is that girls are already outshining their male counterparts in every subject, consistently.

Do you split the children to benefit the girls, or do you leave things as they are and try to improve the performance of male pupils within a mixed sex environment, without addressing the findings of the study?

Why did you come to your conclusion?

Please spread this, I want to see what people would do given this choice.
