Incepe scoala: :-) sau :-(

Fie ca va place sau nu, maine incepe scoala. Dupa o amanare de o saptamana de la programul initial, maine va avea loc in fiecare scoala deschiderea oficiala a anului scolar 2012-2013. Structura anului este aproximativ cea de anul trecut, exceptie facand vacanta de Paste de o singura saptamana. Mai exact, primul semestru se va termina inainte de Craciun, urmat de o vancanta de 3 saptamani si un al doilea semestru foarte lung. Dupa cum spuneam, vacanta de Paste are o singura saptamana in loc de 2 si nu cuprinde sarbatoarea pascala de pe 5 mai, vacanta situandu-se intre datele de 15-21 aprilie.

Revenind la evenimentele apropiate, in a doua saptamana de scoala se vor da TESTELE PREDICTIVE, care (pentru cei ce nu-si mai aduc aminte) sunt acele teste care nu se trec in catalog, dar conteaza enorm pentru prima impresie a profesorilor, deci... MULT NOROC!

Si in incheierea acestui articol vreau sa va urez SUCCES tuturor celor ce (re)veniti in bancile scolii de maine si ultime ore de vacanta placute!

"Knowing" - a great mystery, drama and Sci-Fi story

"Knowing" is a quite old movie, from 2009, which brings Nicolas Cage and Chandler Canterbury in the center of a story categorized by some critics as a thriller, but in fact nothing scarier than just a very exciting combination of mystery, Sci-Fi and some of a drama.

Anyway, the movie presents the story of a teacher which opens a time capsule with drawings of the future made 50 years ago by some old students and gives an envelope with a drawing to every pupil at that school. An astro-physics professor's son gets a "drawing" with a lot of numbers, apparently random, which proves to be a...

How to download an entire photo album from Facebook?

I'm sure that sometimes you needed to download an entire album from Facebook and your only solution was to manually download every single picture, but today I'll show you 2 quick methods to solve this problem:

1. PICK 'n ZIP it's a simple online software which downloads albums from your Facebook account, your friends' accounts or other accounts' albums in which you're tagged. You don't need to install anything on your computer, just log in to Facebook through picknzip.com and follow the steps there.

1. If you navigate with Google Chrome (and if you don't, today it's a great day to start) download from the Chrome Webstore the DOWNLOAD Fb ALBUMS extension.

C++: The "strcat" and "strcpy" functions

Today I'm going to introduce you 2 new functions from the "string.h"  library: "strcpy" which copies the content of a string in another one and "strcat"  which concatenates 2 strings.

I can't show you the syntax of these to functions better than with an example, so let's try to solve the following problem: In the input file there are 2 strings, "x" and "y". You have to create a "z" string with the content from the "x" string, followed by the content from the "y" string and between them the word "and". After that, print on the screen the 3 strings

problem.in

apples

pears

problem.out

the x string is apples

the y string is pears

the z string is apples and pears

Here you are the source-code for the problem, using the 2 functions:
#include <string.h>
#include <stdio.h>
int main ()
{
         freopen("problem.in", "r", stdin);
         freopen("problem.out", "w", stdout);
        char x[1000],y[1000],z[1000];
        int i;

        //now we'll read the 2 strings from the input file
        gets(x);
        gets(y);

        //in the next we'll copy the string "x" in the string "z"

"Sea Rex: Journey to a Prehistoric World", only in IMAX

Sea Rex is a documentary movie which brings the T-Rex of the seas in the most amazing 3D technology, in IMAX theatres. The movie its not quite a documentary, giving you the chance to experience a wondrous adventure from the dinosaur age in a more real way and so, to immerse yourself in a lost age, 200 million years back in time...
This movie has unbelievable effects and lets you see science come alive in an entertaining way, so I can say that Sea Rex deserves attention even just for its effects and technology.

This fall redefines technology

Seems like the most expected operating systems and devices are coming one after each other in September and October, when is announced the beginning of a new age of technology, because these are not just some little steps forward from the same main design idea: they represent a radical change of the appearance and main utilities with which we have already got used from the biggest companies, Apple and Microsoft, adapted to the change of modern man's lifestyle and also to the younger generation, which uses gadgets full-time.
Ending the generalization, let's see the spectacular releases concrete:

• iPhone 5 running iOS 6

iPhone 5  may have a curved design...

iPhone 5 is a very expected smart-phone, since before the release of iPhone 4S. As we already know, Apple doesn't show its creations before the official release, so we need to wait until September 12th, when it will see the light of stores. Of course, that there are enough rumors about how will it look like, so let's see some of them:

...or it may be transparent!

Words in English that are often confused

Here you are a list with some usual words, in English, that use to be confused. It's very helpful for all of us to read this list, but also interesting, because we see how some different groups of letters are pronounced in the same way.

• accept verb: Please accept this gift.

except preposition: every day except Friday.

• advice noun: He always gives good advice.

advise verb: I wouldn't advise doing that.

• affect verb: Tiredness affects concentration.

iOS 6 coming this fall

On the website of Apple, on iPod's dedicated page you can see a very important announce, which looks like this:

"iOS 6 coming this fall!"

It's not very unexpectedly, but now we know for sure that iPhone 5 will come with a brand new operating system.

Of course, you think that when you click on this link, you'll "Get a preview!" , but instead you'll see an article about iOS 5!!!

The Yoyo Cell

SITUATION: "You, walking down the street, stressed about your discharged phone and bored to death... :-("

Talking about the presented situation (which happens to everybody pretty often), we see that it comes with 2 problems, so 2 necessities. First: a phone charger and 2nd: a toy.

The Yo yo Cell

Well, I have the perfect solution for this situation: THE YO YO CELL!!!


It has the basic functions of a phone and by dragging out its built-in earphones cable it turns into a yo yo. Playing with the yo yo, you charge the phone!!! Isn't it perfect?

The Yoyo charge

Also, if you don't want to lose the functionality of a smart-phone, you can by a yo yo charger. See it in the picture.


Would you buy a yo yo cell or a yo yo charger? I think the 2nd option is really interesting.

C++: Diferente intre Borland C++ si MinGW

Diferentele dintre aceste 2 medii de programare sunt putine la nivel incepator, mediu si nu foarte avansat, insa la nivel profesionist acestea incep sa se inmulteasca. In acest articol, va voi prezenta CELE MAI SEMNIFICATIVE 7 DIFERENTE DINTRE BORLAND C++ SI MINGW, suficiente pentru categoria intai enumerata.

1. Functia principala ("main") nu mai poate fi declarata de tip "void" (ca in Borland), ci doar de tip "int", implicand aparitia randului de comanda "return 0;", la sfarsitul programului.
2. Dupa anumite biblioteci (precum "fstream", "iostream" si "algorithm") mai trebuie introdusa comanda pentru alocare de spatiu: "using namespace std;".
3. ".h" - ul de la finalul tuturor bibliotecilor din Borland dispare in unele cazuri (ex. "fstream" si "iostream"), iar in celelalte cazuri se pastreaza (ex. "math.h" si "stdio.h") si se poate inlocui cu un "c" la inceput, ambele fiind corecte in MinGW (adica se poate scrie "stdio.h" sau "cstdio").
4. Limitele se maresc foarte mult pentru tipurile de declarare a varibilelor, "int" ajungand aproape cat vechiul "long"!!!
5. Programul primeste un "WARNING" daca nu este dat un "Enter" la sfarsitul sursei, astfel incat cursorul mouse-ului sa fie pe randul urmator, ca in imagine:

5 Curiosities about animals

Did you know that...

1. the giraffe is pregnant 475 days and it can give birth to only one baby once?
2. the jellyfish from the Turritopsis Nutricula species are immortal?
3. the white rhino is the 2nd largest land animal, after the elephant?
4. the wolf can move his eyes for 250 degrees?
5. we have 98% genetical features common with the monkeys?

Introduction in Origami

Today I've decided to start a new series of articles about origami, the traditional Japanese art which consists in creating paper figurines. For the beginning, you should know why it is called "origami": the name comes from the Japanese words "ori", that means "to fold", and "kami", that means "paper".


The base of origami is folding the coloured paper, for representing different animals, birds, boats, flowers etc. obtained by various combinations of surfaces and lines. There is the possibility of creating a large diversity of figurines, which confers a plus of originality to this art.

Some people treated origami as a simple game, but the most of them considered it as art, due to the possibility to represent creatively and realistically different subjects. The true beauty of the origami art is...

iGoogle will not be available anymore starting with November 1st, 2013!

Google decided to withdraw the iGoogle service from November 1, 2013! This announcement appears under the search box from the page.

How did Google come to this decision?

Google explained their decision as following: " We launched iGoogle in 2005 before anyone could fully imagine the ways that today's web and mobile apps would put personalized, real-time information at your fingertips. With modern apps that run on platforms like Chrome and Android, the need for something like iGoogle has eroded over time, so we’ll be winding down iGoogle on November 1, 2013, giving you a full 16 months to adjust or easily export your iGoogle data."

What will happen with our personal data stored on iGoogle's gadgets?

Google will not erase the data stored in the gadgets and will make them still accessible for you via other Google products linked with your account (Gmail, Google Docs, Google Finance, Google Calendar and other).

At the moment, 7.1 million people use iGoogle and for 6.5 million of them it represents the homepage. This means lose of interest?

Un elev absolvent de liceu care a sustinut probele de bacalaureat anul acesta a intocmit o scrisoare de protest pe foaia de examen, in loc sa rezolve subiectele. In aceasta mult controversata scrisoare, elevul da vina pe societate pentru rezultatele dezastruoase din invatamantul romanesc, pe faptul ca ne sunt promovati ca modele oameni al caror nivel intelectual nu poate fi dat exemplu si numeste actuala generatie ca fiind "PRIMII care se vor revolta impotriva voastra (n.r. politicieni si mass-media).

C++: Ciurul lui Eratostene

Ciurul lui Eratostene este o metoda de verificare a numerelor daca sunt prime, destul de lenta si foarte limitata la matematica, dar cea mai rapida la informatica, in cazul in care se cere verificarea proprietatii de prim pentru mai multe numere. In cazul a mai putin de 10 numere se foloseste algoritmul clasic: Verificarea lui "n" daca este prim (varianta clasica).
TEORIA:

Pasul 1: Cream un sir de numere consecutive (de la 2) pana la maximul posibil precizat in restrictiile problemei.

Pasul 2: Incepem cu primul numar (2) si intr-un sir auxiliar cu exact atatea elemente ca primul (in care initial toate sunt 0) marcam multiplii numarului, prin transformarea in 1 a valorilor corespunzatoare acestora, din al II^lea sir.
Pasul 3: Luam urmatorul numar pentru care valoarea sa din al II^lea sir este 0 si repetam pasul 2 pentru numarul respectiv.
Pasul 4: .......

Povestea fustelor scotiene

Cel mai celebru articol vestimentar scotian din toate timpurile este cu siguranta klit-ul, adica fusta scotiana in carouri, ce era si inca este purtata numai de barbati.
In vechime, klit-ul era purtat tot timpul, mai ales in timpul luptelor intre clanurile scotiene, unde se deosebeau dupa tartan.Tartanul reprezenta culorile si modelul carourilor fustei, fiecare model apartinand unui anumit clan regional scotian. Astazi klit-ul mai este purtat la nunti, botezuri si in general, la evenimentele traditionale.
Un obicei din zilele noastre este ca …

Google celebrates the 100th anniversary of Alan Turing's birth

Today, Google celebrates the 100th anniversary of Alan Turing's birth. He was a British mathematician, computer scientist and cryptanalyst, known for The Halting Problem, The Turing Machine, The Turing Award (the equivalent of The Nobel Award for computer scientists), The Turing Patterns, The Automatic Computing Engine and The Cryptanalysis of The Enigma.

Jessie J. la Mamaia, pe 28 iulie, intrarea libera

Unul dintre cele mai asteptate concerte ale verii din Romania va fi cel al lui Jessie J., pe data de 28 iulie, pe plaja H2O din Mamaia, la ora 19:00. Plaja va fi plina probabil cu multe ore inainte, deoarece concertul este cu intrare libera, ca toate evenimentele din cadrul Orange Summer Party.

Jessie J. a devenit faimoasa dupa single-ul sau de mare succes "Price Tag", care a ajuns al 22-lea cel mai vizionat videoclip pe Internet din toate timpurile (il puteti vedea mai jos si puteti asculta melodia oricand de pe iPod-ul din dreapta paginii). Un alt single de succes al artistei este "Domino".

In pregatirea ultimei saptamani de scoala

In saptamana anterioara am inceput deja sa simtim cum aerul greu al scolii isi ia zborul, iar vacanta se resimte deja. Tot atunci, majoritatea elevilor si-au predat manualele, iar orele constau doar in ascultarea colegilor mai lenesi pe timpul anului si in incheierea mediilor. Multi isi fac ultimele calcule ale mediilor pentru mult ravnitele premii!

Arta romanica si stilul gotic

Arta romanica (sec. X-XII)

Arta e influentata in continuare de Biserica si stat. Sculptura este subordonata arhitecturii. Personajele reprezinta sfintii, grotesti, fara proportii si inghesuite in nise de piatra. Aceste grupuri statuare erau spiritualizate. Arhitectura aduce in prim-plan ceva noutati:
- CAPITELUL este reinventat si in locul influentelor antice ale stilurilor doric si corintic sunt inventate personaje monstruoase
- arcul rotund in bolta
- donjonul(turn de observatie) ...

"Heidi" - summary help / test

For doing a great summary you need to start from a reading sheet, or from some ideas about the text. Of course that, before writing these, you must put yourself some questions and answer them, for being sure that you have understood the text perfectly.
By solving the excercices below you will see which parts of the book you need to read again and after that you will can do the summary of "Heidi", by Johanna Spyri, with no problems.

CHAPTERS 1 -> 5

1. Answer these questions: 

• What happened to Heidi's parents? 

•  Why did Dete take Heidi to Grandfather's house? 

LA MULTI ANI de 1 IUNIE!!!

Pentru inceput vreau sa urez "La multi ani!" tuturor copiilor, deoarece astazi este Ziua Internationala a Copilului! Multi parinti vor probabil sa-si duca copiii undeva de ziua lor, motiv pentru care majoritatea muzeelor, primariilor etc. organizeaza activitati speciale cu ocazia zilei de 1 iunie. De exemplu, unul dintre muzeele la care merita sa mergeti este Muzeul Taranului Roman, unde copii vor fi primiti gratuit si unde se organizeaza un targ special in curtea muzeului, cu multe surprize. 
In unele orase, in scoli, orele de curs au fost inlocuite cu jocuri, concursuri, ore de lucru manual (olarit etc.) si multe altele, iar primariile au impartit cadouri micutilor.
Deasemenea, pentru cei care se tem de aglomeratii, trebuie spus ca atmosfera de sarbatoare se va prelungi pe intregul week-end!

LA MULTI ANI

TUTUROR COPIILOR!!!

Albert Einstein

Albert Einstein is one of the most well-known geniuses in the history. His most famous discovery is E=mc^2, but also The Theory of Relativity was signed by him and many others.
Einstein lived in the 20th century and he made huge progresses in Physics and Mathematics.
He was known as a good person and he like to help kids. Einstein was married twicw and he had a daughter and two sons.
His theories wore and still are very controversed and missunderstood, especially The Special Relativity.
He was born on the 14th of March, in 1879, in Germany and he died on the 18th of April, in 1955, in United States. During his life, Albert Einsteinlived in 7 countries and received 6 different citizenships
Einstein's notable awards are:

• Nobel prize in Physics (1921)
• Matteucci Medal (1921)
• Copley Medal (1925)
• Max Planck Medal (1929)
• Time Person of the Century (1999)

C++: Functia “sort”, cea mai rapida metoda de sortare a vectorilor

Pana acum cunoastem ca metoda de sortare a vectorilor bubble sort-ul, adica algoritmul cu for in for sau cel cu do while, dar astazi vreau sa va arat o functie care sorteaza vectorii, reprezentand  si cea mai rapida metoda posibila si cea mai scurta din punct de vedere al codului.
Aceasta functie se numeste sort si face parte din biblioteca <algorithm>. Iata-i codul in program pentru cazul ordonarii crescatoare a vectorului “v” cu “n” elemente, care a fost citit incepand cu pozitia 0:

sort(v, v+n);

In cazul in care scrierea in vector se incepe de pe pozitia 1, apelarea functiei va arata astfel:

sort(v+1, v+n+1);

Poate ca acum ma veti intreba cum se realizeaza ordonarea descrescatoare. Ei bine, pentru aceasta mai trebuie definita de catre utilizator urmatoarea functie (pentru a afla cum se defineste o functie vezi articolul: Functii definite de catre utilizator) :

bool  descr(<tip> a, <tip> b)
{

C++: Interclasarea

Avand la dispozitie doua tablouri unidimensionale, adica 2 vectori, cu elemente ordonate (crescator sau descrescator) trebuie sa construim un al 3-lea tablou care sa contina elementele primelor 2, respectand acelasi criteriu de ordonare.

Varianta I, cu un timp de executie ridicat

O prima idee ar fi aceea de a reuni elementele celor 2 vectori intr-un al 3-lea, pe care sa il sortam apoi crescator sau descrescator. Rezultatul obtinut dupa efectuarea acestei metode este, bineinteles, cel asteptat, insa dupa cum stim operatia de sortare este mare consumatoare de timp si de aceea aceasta metoda este ineficienta, avand in vedere faptul ca beneficiem de vectorii A si B gata ordonati.


Algoritmul cel mai rapid pentru problema data se numeste INTERCLASARE si este foarte cunoscut si important, dar nu pentru incepatori (primul an de studiu). Mai jos, dupa urmarirea unei analize pas cu pas (cu imagini si explicatiile aferente acestora) a unui exemplu concret de interclasare pe vectori, pentru a intelege ideea de la baza interclasarii, veti gasi algorimul ce realizeaza procedeul descris.

Evaluare in Educatie - Etapa a III-a

Astazi (12 MAI) se desfasoara etapa a III-a a concursului Evaluare in Educatie (numit si "Constantin Nastasescu"), sectiunea matematica, iar sambata viitoare (19 MAI) va fi etapa a III-a la sectiunea de lb. si literatura romana a aceluiasi concurs.
In cadrul concursului, fiecare sectiune este independenta si se desfasoara in 3 etape + 1 nationala. Participarea la primele 3 etape se face fara calificare, iar daca obtii 100/100 pct. la oricare dintre etape te califici la etapa nationala.
Subiectele de la primele etape nu sunt foarte grele si se incadreaza in programa scolara facuta pana la momentul desfasurarii concursului, deci va recomand sa mergeti la concurs, deoarece nici premiile nu sunt de neglijat.
Rezultatele le puteti gasi pe site-ul oficial al concursului, www.evaluareineducatie.ro/matematica.

MULT SUCCES PARTICIPANTILOR!!!

Seesmic: a great social app

Seesmic is a wonderful app for PC, BlackBerry, iOS and Android, for those which enjoy using Facebook and Twitter and want to access all of their profiles on the way, with just a single app.
For all the platforms there are a free and a paid version, but I sustain that the free version is more than enough, at least the one for Android (there are a few differences between the features that appear on Android and the ones that are on iOS, BlackBerry and PC). On the PC you also can make free video calls!!
The developers promised that in the next version you'll also be able to bring your Google Plus and your 9GAG accounts in the free app. Isn't it great?
To bring an account in the Seesmic app means to have access to your Wall, friends, photos, posts, profile, pages, notifications etc.
But what is so revolutionary at Seesmic? Well, actually...

Unghiuri determinate de doua drepte taiate de o secanta

• O dreapta se numeste secanta a 2 drepte daca intersecteaza cele 2 drepte in puncte diferite.
• (Figura 1):   Dreapta d este secanta a dreptelor a si b deoarece    si
, iar A si B fiind puncte distincte.

• (Figura 2): 2 drepte determina cu o secanta 8 unghiuri care, imperecheate intr-un anumit mod, poarta diferite denumiri, dupa pozitiile pe care le ocupa fata de dreptele date. Astfel:
• unghiurile 3 si 5 sau 4 si 6 se numesc alterne interne
• unghiurile 1 si 7 sau 2 si 8 se numesc alterne externe
• unghiurile 3 si 6 sau 4 si 5 se numesc interne de acceasi parte a secantei
• unghiurile 1 si 8 sau 2 si 7 se numesc externe de acceasi parte a secantei
• unghiurile 1 si 5, 4 si 8, 2 si 6 sau 3 si 7 se numesc corespondente

Pastelul - definitie

Pastelul este:

• o specie a genului liric (un text alcatuit din versuri, grupate in strofe si cu elemente de prozodie: rima, ritm si masura)
• prezentarea unui tablou de natura (descriere lirica), pentru care se folosesc:

                    - multe enunturi nominale (multe substantive, adjective si adverbe; putine verbe)
                    -multe figuri de stil si imagini artistice

• un text in care nu apar marci lexico-gramaticale ale prezentei eului liric, atitudinea acestuia fiind contemplativa (priveste detasat)
• un termen ce provine din pictura, unde desemna un desen facut cu creioane moi
• o specie introdusa
