I will split the book into 3 main parts and how i perceived them based on their span in %
1. 0-30% This is the most interesting part since the author sheds light onto the mechanisms of sleep , the brain parts that facilitate it , how it evolved (monophasic/biphasic) , and how it manifests within nature. It includes interesting info for example how birds manage to sleep when in transit , whales etc. This part also decomposes sleep by its type : REM Sleep and Non REM Deep Sleep and explains why we need both , which is used and how , how are each of these wavelengths looks like on an oscilloscope etc. Really really fun and cool stuff !
2. 30-75% The hardest part to read.This huge chunk is basically an entire manifesto on the proven (and mostly unproven) dangers of not sleeping enough. While i unnderstand the author tries to prove a point , he starts to just throw around hypotheses and as he himself admits unproven experiments , that sleep is the main culprit and heavily influences a whole range of diseases starting from cardiovadcular , cancers , digestive , brain etc. It starts to look like every human problem is a nail and sleep is THE hammer !
3. 75-100% This is somewhat an average part focusing on how humans could change their habits regarding sleep , how employers could improve their companies by letting workers get their sleep , how entire inndustries andd technology could be devised as to work for our health promoting sleep and not against us like it is now.
All in all i can say the first part was really good , the second part after some point starts to become boring and really painful to read , ending with a mediocre one where you can find a couple of good tips regarding your sleep.
All in all a letdown mostly due to the second part and all the hype around it....more
This book is a testimony to what true will power means but also what a strong motivator desperation can be.
Even though the hype is all about the girl This book is a testimony to what true will power means but also what a strong motivator desperation can be.
Even though the hype is all about the girl that changes her fate in order to escape a life governed by devotion , fear , indoctrination , centered around the family , i find it fabulous by how intimate, seamless almost symbiotic the elements of the two planes interwined for the girl's father .
On one hand , you behave like a nutjob and herd your children across the mountains , put them through hard , dangerous , unprotected labour (welding,raising barns , scraping metal,forklifting) , despise all kinds of civilisation , ban doctors and modern medicine , make use of midwives , fear the gonvernment and atttribute your resolve on god's will , for the end days are upon us.
On the other hand you have no problem using technology including internet & email , opening an enterprise of your own products , stockpile on guns , ammo (including a 50cal) use cars , trucks , forklifts and whatever , metal shears , chain saw in order to make money to buy provisions to again prepare for the end days.
All in all a total delight. This books proves the nasty effects of mentally unstable people on their families if left unchecked....more

I enjoyed how the book treated subjects such as : caching, security , consistent connections and proxies.

It is really incredible how the author begins the journey from the lowest OSI layer to the browser and the newest trends in realtime communication.
The book starts with detailing each different medium (fiber, satellite , radio , wifi) we can nowadays use in order to send packets over the network.Interestingly enough he gets you into data transmission , signal processing , electronics and physics in order to give you an idea on how each medium impacts your app's performance and their hidden latencies.
The book then shifts to TCP and UDP, TLS, TURN , ICE and STUN protocols.Awesome chapter , i would have never known the intricacies of TCP and its adaptability regarding the unreliability of the underlying network.(The congestion window mechanisms part was insane).
Another chapter is dedicated to wireless networks.
The most interesting part was the one regarding mobile networks. The author does a terrific job by first explaining how your handset works , how it efficiently uses its battery in order to accomodate the ever consuming radio(s) (2G,3G,4G) , its complicated RRC (radio resource controller) protocol that manages the exchanges with the radio tower and handles your phone state-machine that manages your battery and its sensible connection with its radio.
Then he goes overdrive detailing LTE radio networks , with their architecture and components (RAN, ETC-SGW,PGW,MME) , the way they manage to serve users that are in constant motion (MME) switching them from radio tower to radio tower , updating their position in realtime and performing billing and security checks ; the way they direct packets from the public internet to their gateways ,parse , corect them , resolve users , find corresponding tower and negotiate protocols with the user handset to in the end forward the message. Its really interesting that the principles of clustering and load balacing that apply nowadays to any web application component (database, api , web app) were present in the telecom domain for a very long time and more importantly , not only for software but for radio towers as well.
The book then moves to HTTP , HTTPS , XHR(interesting history part here ) , SSE , Websockets and last but not least WebRTC.
Even though the last part was detailed and interesting i found it nowhere close to the one regarding mobile networks( could be due to the fact that i was already familiar with the concepts)
Awesome read and i recommend it wholeheartedly for anyone interested in building high performance applications.It is one of those reads which takes a hollistic view on all the layers and components involved to give you a neat idea on how to build something !...more
A total must read for anyone that wants to : - start a business - get some accounting basics - invest in the stock market (my case)
I knew there is alot mA total must read for anyone that wants to : - start a business - get some accounting basics - invest in the stock market (my case)
I knew there is alot more to company valuation then reading bloomberg news , checking the P/E ratio , ROI and Growth.
This book provides you with the building blocks of starting a business and of course by learning how to build , one learns to evaluate one business worth.
Impressive diagrams , schematics and comments. This book brings you in ~300 pages from zero to hero in thr field of finance , accounting , management and investing.
The author treats the financial statements in depth , taking all items one by one and discussing , explaining the intricate relationships betweeen them.
It is a shame books of financial tycoons such as Buffett/Lynch and all those "startup gurus" get all the media while this hidden gem is barely noticeable.

Not pretty much to learn if you are interested in learning the in's and outs of the market.
I must admit however that the author did a great job in the last 3 chapters when discussing on subjects such as current accounting practices , goodwill and taxation.
Overall a book designsted torwards general managers or people with out of the ordinary financial resources.
If investing it is you are interested in then i suggest grab a copy of Peter Lynch's One up on Wall Street ASAP !...more
Having googlers reason about their giant architecture, the difficulties it imposed and then explain on how they handled them is invaluable for any IT Having googlers reason about their giant architecture, the difficulties it imposed and then explain on how they handled them is invaluable for any IT engineer.
While reading it , it might (hopefully) occur to you that there's a whole new world out there , at a total different scale with problems that need solving that you could not even imagine ( Multi Paxos , Resource Planning , Borg , Big Table etc...)
I see this book as a creativity additive before all else....more
By far the best book i've read on investing so far.While there are a dozen books that cover the basics and and tell you what to look for when choosingBy far the best book i've read on investing so far.While there are a dozen books that cover the basics and and tell you what to look for when choosing stocks, this is the first one that tells me as a novice why a particular value on the financial statements matters.
Peter Lynch does an awesome job in splitting stocks into 6 categories (slow ,fast growers, stalwarts, cyclicals,turnarounds and asset plays).
After separating them , he goes on explaining what to expect from that category and what indices really matter on the financial statements.
On top of that he provides real decisions that he has made during his career as director of Magellan Fidelity investment fund.
There's one thing to read in a random book about the balance sheet and there's another to read on how he bought Ford stock in 1987 based on analysing Cash vs Long term Debt.
These examples are abundand and are godly for the novice investor to get the nuts and.bolts on how the stock market works.
Terrific read , i reccomend it wholeheartedly !...more

Ce mi s-a parut de mare interes este originea protagonistului si a camarazilor sai: un biet pustan neamt de 19 ani care impins la spate de dascali si cunoscuti s-a inregimentat.
Scrierea este clara , iar paginile zboara deoarece majoritatea mustesc cu actiunea frontului si intamplari de zi cu zi ale soldatului german .Descrierile sunt cu advarat autentice.
O recomand cu caldura atat celor pasionati de aceasta perioada tulbure cat si celor care vor sa isi forneze o idee !...more

Dr Greger goes to great lengths to explain what and why each food does for the body or against it. What i found awesome is that besides providing a template for what foods are a must to eat daily and how much of each, he also gives ideas on how to incorporate these foods in your daily meals.
Compared to The China Study , i found this book to be alot more practical and detailed.(Might be because the author has also read the Study)....more
