apps para diminuir o stress, combater insónia, acabar com a ansiedade...

apps Personal Trainers

1. Diminuir o stress

“Calm” é uma aplicação que, tal como o nome indica, promove uma sensação de calma, relaxando o sistema nervoso. Basta selecionar a duração da sessão (entre 2 a 20 minutos) e escolher uma imagem da natureza como cenário de fundo. Para acompanhar, do som das ondas do oceano até ao ruído da chuva, as opções são infinitas. Uma lufada de ar fresco com uma versão online que pode experimentar aqui. O uso de headphones é, obviamente, recomendado (não só nesta como na maior parte das aplicações aqui referidas).

3. Acabar com as insónias

As insónias são um problema sério para muitas pessoas e é por isso queGlenn Harrold decidiu lançar a aplicação “Relax & Sleep Well”. Se quer evitar pertubações do sono, experimente ouvir a “sleep version” para adormecer mais rápido. Já a “awake version” visa estimulá-lo/a para o novo dia e deve ser ouvida assim que acorda. Duas versões que pretendem acabar com as preocupações, stress e ansiedade que impedem uma boa noite de sono.

9. Acabar com a ansiedade

Take A Break” não é mais do que uma pausa que promete acabar com os momentos mais stressantes de um dia caótico. Existem duas sessões, uma de sete minutos e outra de 13, com diferentes músicas de fundo especialmente pensadas para transmitir uma sensação de calma e segurança. “Comece por deixar em pausa tudo aquilo que estava a fazer e deixe a sua imaginação fluir”, explica uma voz suave.

Canon 100d review

Ken Roockwell on rebel sl1 aka canon 100d

The question is, how to improve quality? should I get a L lenses to step up to the next level?... my quest is in the wide zoom arena where I already have the 18-55stm and a 18-50 F2.8 tamron. and the 24stm and the 40stm...

but 17-40 L is outdated and doesn't perform well with the new >8 megapixel sensors, 2.8L are big and heavy. the new 16-35L F4 is also heavy and expensive.

maybe the new 24-70L F4 is what I need?

Ken Rockwell comparisons sl1-vs-5d-mk-iii

it seems it'll cost thousands to improve quality and improvement will be noticed mainly under special conditions: mostly with lowlight. (not really surprised here, but I expected bigger differences under better light, I'd say).

So to improve quality, the best option (for a non professional) is to spare some bucks and take more shots, learn how to use the camera (e.g. sharpening 6 and saturation 3or 4 for nature and 0 or 1 for people), avoid the lenses weakest perfomance zones (usually wider and bigger aperture for wide lenses - e.g. I avoid on my tamron 17-50 the 17mm specially with F2.8 whenever possible, and max. apertures on my 18-55 stm or 40stm. with these lenses going for a F/5.6 or F/8 we usually boost quality in reducing vigneting and cromatic aberrations and putting resolution at its best)
and get the best light (time of day, positioning).

I don't think 100d will match a 5d when dealing with noise, nor the stm lenses beat the L lenses in vigneting or chromatic aberrations but, under a resonably good light, stepping down the stm lenses away from max apertures (only one or two steps will make a big difference) I'll be close to the 5d / L lenses quality. resolution? hardly I'll spot differences, specially in center.

Macro Photography, using extension tubes

Extension tubes

The cheapest tube set with electric contacts is about $60 to $70 I understand. At least, it was that a couple of months ago, although prices may have gone up by now. Just check Amazon or the B&H site. For a good set but more expensive, get a Kenko 3 tube set (plastic), and if you want metal the only option is Canon. However, with a 40 mm you could just get away with a 12 mm tube to begin with anyway. As this lens has an MFD of 25 cm, a 12 mm tube at MFD will give you a new MFD of approximately 175 mm with 113 mm WD and a magnification of 1:0.55, or slightly better than half size. A 25 mm tube 161 mm MFD, 86 mm WD, and magnification of 1:0.875. A 30 mm tube will provide you with 1:1 for this lens.
The most important aspect of having tubes with contacts is the ability to control the aperture on an EF or EF-S lens."

the future of management - Gary Hamel

Gary Hamel - Future of management << quotes and preface

In The Future of Management, Gary Hamel argues that organizations need management innovation now more than ever. Why? The management paradigm of the last century—centered on control and efficiency—no longer suffices in a world where adaptability and creativity drive business success. To thrive in the future, companies must reinvent management.

"how do you build organizations that are as nimble as change itself"

 “Like the combustion engine, it's a technology that has largely stopped evolving, and that's not good.” What then does the future of management hold? Hamel timidly won't say. “My goal in writing this book was not to predict the future of management, but to help you invent it,” he wrote. Useful things to bear in mind, he suggested, are the need for companies to have purpose, to seek out ideas from the fringes, and to embrace the democratising power of the internet.

Mental toughness

First the definition:
"The ability to work hard and respond resiliently to failure and adversity; the inner quality that enables individuals to work hard and stick to their long-term passions and goals."
Now the word:
The definition of grit almost perfectly describes qualities every successful person possesses, because mental toughness builds the foundations for long-term success.
For example, successful people are great at delaying gratification. Successful people are great at withstanding temptation. Successful people are great at overcoming fear in order to do what they need to do. (Of course, that doesn't mean they aren't scared — that does mean they're brave. Big difference.) Successful people don't just prioritize: They consistently keep doing what they have decided is most important.
All those qualities require mental strength and toughness — so it's no coincidence those are some of the qualities of remarkably successful people.
Here are ways you can become mentally stronger — and as a result more successful:

1. Always act as if you are in total control.

There's a saying often credited to Ignatius: "Pray as if God will take care of all; act as if all is up to you." (Cool quote.)
The same premise applies to luck. Many people feel luck has a lot to do with success or failure. If they succeed, luck favored them, and if they fail, luck was against them.
Most successful people do sense that good luck played some role in their success. But they don't wait for good luck or worry about bad luck. They act as if success or failure is completely within their control. If they succeed, they caused it. If they fail, they caused it.
By not wasting mental energy worrying about what might happen to you, you can put all your effort into making things happen. (And then if you get lucky, hey, you're even better off.)
You can't control luck, but you can definitely control you.

2. Put aside things you have no ability to affect.

Mental strength is like muscle strength — no one has an unlimited supply. So why waste your power on things you can't control?
For some people it's politics. For others it's family. For others it's global warming. Whatever it is, you care … and you want others to care.
Fine. Do what you can do: Vote. Lend a listening ear. Recycle and reduce your carbon footprint. Do what you can do. Be your own change — but don't try to make everyone else change.
(They won't.)

3. See the past as valuable training … and nothing more.

The past is valuable. Learn from your mistakes. Learn from the mistakes of others.
Then let it go.
Easier said than done? It depends on your perspective. When something bad happens to you, see it as an opportunity to learn something you didn't know. When another person makes a mistake, don't just learn from it — see it as an opportunity to be kind, forgiving, and understanding.
The past is just training; it doesn't define you. Think about what went wrong but only in terms of how you will make sure that next time you and the people around you know how to make sure it goes right.

4. Celebrate the success of others.

Many people — I guarantee you know at least a few — see success as a zero-sum game: There's only so much to go around. When someone else shines, they think that diminishes the light from their stars.
Resentment sucks up a massive amount of mental energy — energy better applied elsewhere.
When a friend does something awesome, that doesn't preclude you from doing something awesome. In fact where success is concerned, birds of a feather tend to flock together — so draw your unsuccessful friends even closer.
Don't resent awesomeness. Create and celebrate awesomeness, wherever you find it, and in time you'll find even more of it in yourself.

5. Never allow yourself to whine. (Or complain. Or criticize.)

Your words have power, especially over you. Whining about your problems always makes you feel worse, not better.
So if something is wrong, don't waste time complaining. Put that mental energy into making the situation better. (Unless you want to whine about it forever, eventually you'll have to make it better.)
So why waste time? Fix it now. Don't talk about what's wrong. Talk about how you'll make things better, even if that conversation is only with yourself.
And do the same with your friends or colleagues. Don't just serve as a shoulder they can cry on. Friends don't let friends whine; friends help friends make their lives better.

6. Focus only on impressing yourself.

No one likes you for your clothes, your car, your possessions, your title, or your accomplishments. Those are all "things." People may like your things — but that doesn't mean they like you.
(Sure, superficially they might seem to like you, but superficial is also insubstantial, and a relationship not based on substance is not a real relationship.)
Genuine relationships make you happier, and you'll form genuine relationships only when you stop trying to impress and start trying to just be yourself.
And you'll have a lot more mental energy to spend on the people who really do matter in your life.

7. Count your blessings.

Take a second every night before you turn out the light and, in that moment, quit worrying about what you don't have. Quit worrying about what others have that you don't.
Think about what you do have. You have a lot to be thankful for. Feels pretty good, doesn't it?
Feeling better about yourself is the best way of all to recharge your mental batteries.
