closest book meme

  • Grab the nearest book.
  • Open it to page 56.
  • Find the fifth sentence.
  • Post the text of the sentence in your journal along with these instructions.
  • Don’t dig for your favorite book, the cool book, or the intellectual one: pick the CLOSEST.
The following comes the book that, I think, was closest to me at the time, although it was hard to tell for sure since there tend to be books strewn around my apartment:

"Taking Burgundy and Provence peaceably by marriage, he proceeded to make Italy the fulcrum of his new empire."

The quote comes from
A Mighty Fortress: A New History of the German People A Mighty Fortress: A New History of the German People by Steven Ozment.

Developing with libyui/libzypp & python – part4

Let’s extend the application to make it even more useful!

* add support for YaST-Repositories

* add Support for different architectures

* use always a random temporary directory

Now, it looks like this:

Picture of the Application

You can grab it out of my home: in the openSUSE Build Service (for openSUSE 11.0).

Start it with “repoviewer”, add the repository’s url, select the type, the architecture and hit “Go!” .
You can choose the architectures only for the “highest” type of the family as they list the “lower” types, too.
So to see “ppc” packages. use “ppc64” in the combobox and later “ppc” in the “Arch” column.
For big repos (like factory) it takes some time to download and parse the metadata.

Also try in a console-window:
unset DISPLAY; repoviewer

😉 thanks to libyui, that just works !
Update: You can access also local directories (like mounted CDs/DVDs).
Just use “file:///” and the full path ! E.g.: “file:///media/SU1100.001/”

Книга по С++, которую я прочитал первой

Нашел я и книгу, которую прочитал первой при изучении языка С++. Она мне нравилась простотой и последовательностью изложения. Ее удобно использовать, изучая язык. Мне это в ней и нравилось. В настоящее время я, к сожалению, ее уже не имею в своем распоряжении, чтобы подробнее описать. Причина отсутствия: "подарил школьной библиотеке". Так что в школе, где я учился и работал, стало на одну книгу по С++ больше. "Отличный язык в широкие массы!!!".
А вот и ссылка на книгу:

Книга по С++

На вопрос: "Какую книгу почитать по С++?", я предлагаю прочитать книгу Бьерна Страуструпа. Книга интересная, глубокая. Можно прочитать ее поверхностно, выяснив только те вопросы, которые Вас интересуют, а можно копнуть глубоко, прочитав "от корки до корки". Использовать ее как справочник мне очень нравится. Четкое изложение, наличие примера - все что надо для "прояснения вопроса".

Эту книгу я прочитал не первой, однако, купив ее, пользуюсь постоянно.

Перегрузка операторов перенаправления из потока и в поток

Когда мы используем вывод на консоль, то часто пишем следующий код:
std::cout<<"Hello, world"<<std::endl

Предположим, что мы создали класс следующего вида:
class TestClass{
public:
TestClass();
~TestClass();
private:
int i;
std::string s;
};

Для вывода содержимого класса на экран можно воспользоваться созданным специально для этого методом:
class TestClass{
public:
TestClass();
~TestClass();
void output(); // метод для вывода на консоль
private:
int i;
std::string s;
};

void TestClass::output(){
std::cout<<"i="<<i<<"s="<<s<<std::endl;
}

Тогда вывод для экземпляра будет выглядеть так:
TestClass tc;
tc.output();

Такой вариант возможен, но он очень уж некрасив. Переопределим оператор перенаправления в поток, что позволит нам перенаправлять содержимое экземпляра класса в поток вывода:
TestClass tc;
std::cout<<tc<<std::endl;

Для этого реализуем друга класса следующего вида:
class TestClass{
public:
TestClass();
~TestClass();
friend std::ostream& operator<<(std::ostream& out, const TestClass& c);
private:
int i;
std::string s;
};
std::ostream& operator<<(std::ostream& out, const TestClass& c);

Что содержится в теле данного оператора? В нем должен быть реализован функционал по перенаправлению полей класса в поток вывода, например:
std::ostream& operator<<(std::ostream& out, const TestClass& c)
{
out<<"i="<<c.i;
out<<" s="<<c.s;
return out;
}
Т.к. оператор является другом класса, то он имеет доступ к приватным полям класса, что не требует от нас делать их публичными.

Теперь, используя написанный код, можно выводить содержимое класса на консоль:

TestClass tc;
std::cout<<tc<<std::endl;
TestClass *p=new TestClass();
std::cout<<"second: "<<*p<<std::endl;

Zypper 1.0.0

We're closing to the release of openSUSE 11.1 and SUSE Linux Enterprise 11. Since zypper's releases are tightly tied to those of openSUSE, this is also an important milestone for zypper. Thus, the next release of zypper will have version 1.0.0. This marks more than two years of zypper's development and the outset of implementation of new nice features.

So what's next?

Several ideas and problems appeared so far. Some need to be implemented in libzypp itself, some are purely zypper's. Here is a list of the most important things for zypper 2.
  • Configuration file (.zypperrc).
  • Nice overall install progress.
  • Much improved install summary (options to view version/vendor/arch changes, changelog, ...).
  • More options to handle patterns (remove, install suggested, ...).
  • Advanced media error handling with options like eject DVD drive, select DVD drive, edit failed URI, enable/disable medium specific options.
  • Fixed or removed zypper shell (can it be useful enough to be worth to maintain it?)
  • Interface to new libzypp functionality like 'download only'.
  • and more...
First there will be some bug fixes during the beta phase of SLE 11, mainly with respect to compatibility with SLE 10 version of rug. These (and all following releses for SLE) will be versioned 1.0.x and will eventually get also to openSUSE 11.1 via online update. After that we're ready to work on zypper 2.

Stay tuned on features.opensuse.org, this TODO file, this blog and blogs of other ZYpp hackers (see my links).

Kubuntu upgrade from 7.10 to 8.10

I am using Kubuntu in Vmware just to play arround with it, so I decided to upgrade from 7.10 to 8.10, and this means that I will have as well KDE4. The upgrade process has been very easy, but I needed to upgrade first to 8.04 and finally to 8.10, so, here are the steps:

7.10 to 8.04

$ sudo apt-get update
$ sudo apt-get upgrade
$ kdesudo "adept_manager --dist-upgrade" # (using ALT+F2 in KDE)

8.04 to 8.10

$ kdesudo "adept_manager --dist-upgrade" # (using ALT+F2 in KDE)

That's all.
