Pinguy OS What Is Pinguy OS? Ubuntu is a great OS and undoubtedly the most popular and easiest Linux based Distro to use but even with its default setup and chosen programs it's still lacking functionality and ease of use for most new users. So what I decided to do was build a Distro that looks good, could do everything most user would ever want to do and that was very simple to use. I started out by listening to what my friends and family wanted to use their PC for and found the most user friendly programs for the task they wanted to do. After a while I got a good idea what most people use their PC for and what programs were the easiest to use. Like using Shotwell for easily uploading images to Facebook, gtkpod for putting music, photos and video on a ipod/iphone and mvPod for converting the video to a iPod friendly format. So all the programs in Pinguy OS have been chosen because of their ease of use and functionality, I also changed every file type to open with the right program, like for some reason by default .iso are opened with Archive Manager so I changed that to Brasero Disc Burner. As I already said apart from it being easy to use I also wanted it to be a very good looking operating system. There are now a lot of programs out there for Linux to give the OS a very smart and polished implementation, like CoverGloobus, Gloobus Preview, GNOME Do, and Docky. These programs don't just give the OS a good look and feel but they are also very useful and handy. Pinguy OS is an optimise build of Ubuntu 10.10 Minimal CD with added repositories, tweaks and enhancements that can run as a Live DVD or be installed. It has all the added packages needed for video, music and web content e.g. flash and java, plus a few fixes as well. Like fixing the wireless problems, gwibber’s Facebook problem and flash videos in full-screen. Everything is set-up for samba, all you need to do is right click a folder you want to share and add a password in samba using system-config-samba. It also has a UPnP/DLNA server (pms-linux) so you can share your music, video’s etc. With a PS3, XBOX 360, Smart Phones or any other UPnP/DLNA media reader. Nautilus has been replaced for Elementary-Nautilus with added plug-ins so it can get music and video art from the web. The default theme is Elementary using ttf-droid font with Docky and a custom Conky. I have also added DVB support to Totem for anyone with a TV card that wants to watch tv on their PC but doesn't want to install a dedicated program like myth-tv. For a full list of installed programs and repos for 10.04.1 *OLD* download this file. If you prefer to download and install the LTS (long term support) 10.04. It can still be downloaded from here.

Da, ai dreptate. Pfff, nu mai stiu sa fac o inmultire Da, oricum nu cred ca va folosi cineva aceasta clasa pentru numere extraordinar de mari, dar ar fi bun ca exercitiu de programare.

Linux Directory Structure (File System Structure) Explained with Examples Have you wondered why certain programs are located under /bin, or /sbin, or /usr/bin, or /usr/sbin? For example, less command is located under /usr/bin directory. Why not /bin, or /sbin, or /usr/sbin? What is the different between all these directories? In this article, let us review the Linux filesystem structures and understand the meaning of individual high-level directories. 1. / – Root Every single file and directory starts from the root directory. Only root user has write privilege under this directory. Please note that /root is root user’s home directory, which is not same as /. 2. /bin – User Binaries Contains binary executables. Common linux commands you need to use in single-user modes are located under this directory. Commands used by all the users of the system are located here. For example: ps, ls, ping, grep, cp. 3. /sbin – System Binaries Just like /bin, /sbin also contains binary executables. But, the linux commands located under this directory are used typically by system aministrator, for system maintenance purpose. For example: iptables, reboot, fdisk, ifconfig, swapon 4. /etc – Configuration Files Contains configuration files required by all programs. This also contains startup and shutdown shell scripts used to start/stop individual programs. For example: /etc/resolv.conf, /etc/logrotate.conf 5. /dev – Device Files Contains device files. These include terminal devices, usb, or any device attached to the system. For example: /dev/tty1, /dev/usbmon0 6. /proc – Process Information Contains information about system process. This is a pseudo filesystem contains information about running process. For example: /proc/{pid} directory contains information about the process with that particular pid. This is a virtual filesystem with text information about system resources. For example: /proc/uptime 7. /var – Variable Files var stands for variable files. Content of the files that are expected to grow can be found under this directory. This includes — system log files (/var/log); packages and database files (/var/lib); emails (/var/mail); print queues (/var/spool); lock files (/var/lock); temp files needed across reboots (/var/tmp); 8. /tmp – Temporary Files Directory that contains temporary files created by system and users. Files under this directory are deleted when system is rebooted. 9. /usr – User Programs Contains binaries, libraries, documentation, and source-code for second level programs. /usr/bin contains binary files for user programs. If you can’t find a user binary under /bin, look under /usr/bin. For example: at, awk, cc, less, scp /usr/sbin contains binary files for system administrators. If you can’t find a system binary under /sbin, look under /usr/sbin. For example: atd, cron, sshd, useradd, userdel /usr/lib contains libraries for /usr/bin and /usr/sbin /usr/local contains users programs that you install from source. For example, when you install apache from source, it goes under /usr/local/apache2 10. /home – Home Directories Home directories for all users to store their personal files. For example: /home/john, /home/nikita 11. /boot – Boot Loader Files Contains boot loader related files. Kernel initrd, vmlinux, grub files are located under /boot For example: initrd.img-2.6.32-24-generic, vmlinuz-2.6.32-24-generic 12. /lib – System Libraries Contains library files that supports the binaries located under /bin and /sbin Library filenames are either ld* or lib*.so.* For example: ld-2.11.1.so, libncurses.so.5.7 13. /opt – Optional add-on Applications opt stands for optional. Contains add-on applications from individual vendors. add-on applications should be installed under either /opt/ or /opt/ sub-directory. 14. /mnt – Mount Directory Temporary mount directory where sysadmins can mount filesystems. 15. /media – Removable Media Devices Temporary mount directory for removable devices. For examples, /media/cdrom for CD-ROM; /media/floppy for floppy drives; /media/cdrecorder for CD writer 16. /srv – Service Data srv stands for service. Contains server specific services related data. For example, /srv/cvs contains CVS related data. Sursa: http://www.thegeekstuff.com/2010/09/linux-file-system-structure/

De ce n ^ 2? Va fi o inmultire, a cifrelor, o atribuire a valorii de tinut minte si o adunare cu valoarea de tinut minte de la cifra precedenta. Ceea ce inseamna 3 * n operatii, si cred ca nu e rau deloc. Adica nu vor fi multi care vor folosi clasa pentru numere cu milioane de cifre.

Inmultirea se face ca pe foaie. Se ia ultima cifra, se inmulteste cu ultima de la celalalt numar, si se memoreaza intr-o variabila "depasirea", de exemplu pentru 5 * 7 = 35, se pastreaza 5 si se "tine minte" 3, care se aduna la inmultirea cifrelor urmatoare.

javascript:alert(unescape('%3C%74%69%74%6C%65%3E%52%53%54%3C%2F%74%69%74%6C%65%3E')) Da, ca idee e util in anumite cazuri, dar ar trebui obfuscat mai bine, macar ar fi greu de ajuns la rezultatul final. Problema se pune astfel: dar daca utilizatorul are JavaScript dezactivat? In plus, viteza la afisarea site-ului scade.

DA! E, adevarat. Exista si alte categorii in afara de Offtopic, pe langa cele de Tutoriale si Programare pe care probabil nu le-ati vazut si nu le veti vedea niciodata. Categoria AJUTOR, si NU Offtopic, e pentru cei care au nevoie de ajutor, care au o problema si incearca sa gaseasca raspunsul la ea. Iar categoria CERERI, si NU Offtopic, e pentru a cere diverse lucruri pe care nu sunteti in stare sa le gasiti folosind Google. Asadar, NU TOATE TOPICURILE, indiferent de subiect, se posteaza aici, la Offtopic. Am mai facut doua posturi pe aceasta tema. Vedeti si asta: http://rstcenter.com/forum/28329-topicurile-de-la-offtopic.rst Asa cum multi ati observat, daca aveti nevoie de ajutor sau cereti ceva aici la Offtopic veti primi avertisment, si la 3-4-5 avertismente veti fi banati. M-am saturat sa dau avertismente si sa va mut topicurile. Desigur, daca ati post si voi ceva util (ce utopie...), un program sau un tutorial, in aceasta categorie, as muta topicul in categoria specifica fara nici o problema, fara sa primiti nici un avertisment. Dar voi postati toate rahaturile, toate problemele banale si toate cererile stupide aici. Desigur, regula nu se aplica doar aici. Daca postati ceva care nu se incadreaza in categria in care postati, adica daca nu ganditi 2 secunde inainte de a posta, veti primi avertisment. Exemple: #1 - Postezi ca vrei un program la: programe hack, programe securitate sau stuff tools - primesti avertisment. Programul il ceri in categoria CERERI pentru ca lumea sa poata vizualiza acea categorie pentru a descarca programe, nu pentru a vedea de ce program are nevoie Vasile. #2 - Postezi ca nu ti se mai scoala intr-o alta categorie in afara de: offtopic, cele mai penale posturi sau cosul de gunoi - primesti probabil ban, in functie de cat de stupid e postul tau. #3 - Postezi la Offtopic cine stie ce problema pe care o ai cu calculatorul - vorbim cu mamica ta sa ti-l ia, pentru ca nu esti destul de mare pentru a avea unul. Daca te-ar duce capul sa meriti un calculator, ai vedea ca exista categorii speciale unde sa pui astfel de intrebari. Deci, pentru a mia oara, si ca sa nu stau sa explic fiecarei "victime" a avertismentelor mele de ce a primit acel avertisment: Exista categoriile AJUTOR si CERERI Sa nu ma mai trezesc cu tot felul de rebeli nemultumiti de faptul ca au primit avertisment. Daca primesc PM, la care oricum nu prea raspund, sau mai rau, se posteaza in acelasi topic diverse proteste ale "raufacatorului", e posibil sa mai primeasca un avertisment. In plus, acesta este un FORUM, ceea ce inseamna ca se poarta diverse discutii in topicuri, si nu pe PM. Deci nu imi mai trimiteti PM-uri ca aveti nevoie de nu stiu ce, sau ca aveti nu stiu ce problema pentru ca nu am sa raspund la ele. E forum, posteaza si ai mult mai multe sanse sa primesti un raspuns.

Sugestie: char * alocat dinamic pe blocuri. Ai un octet pentru cifra, e de ajuns. Adica, aloci 1024 de octeti, adica suficient pentru un numar de 1024 de cifre. Apoi, daca e nevoie de mai mult, mai aloci 1024. Ca daca faci o alocare pentru fiecare cifra in plus se alege praful. La listele tale, aloci memorie pentru fiecare cifra, deci pauza viteza.

Bun asa, cine mai vine?

De ce liste dublu inlantuite?

O lista dublu inlantuita presupune un pointer catre elementul anterior si unul catre elementul urmator. Asta inseamna 8 octeti pentru fiecare cifra (cred ca vrei sa memorezi cifrele in lista dublu inlantuita). In plus, ca sa ajungi la cifra 100, trebuie sa pornesti de la prima cifra, si sa treci prin celelalte 99, adica si viteza foarte mica. Ai inceput proiectul? Vreau sa vad un inceput, apoi discutam.

SELECT nume,prenume,varsta FROM tabel1 UNION SELECT COUNT(*) FROM table2 ?

Sincer, nu am inteles nimic din ce ai scris mai sus. Nu prea iti inteleg teoriile conspirationiste, si nu aduci nici un argument unor afirmatii stupide si puerile.

Da, sunt politist si il urmaresc pe gicu asta ca e mare infractor, face parte din mafia online, e periculos. Ce dracu ma, daca v-ati folosi doar de ce e postat aici ati putea sti multe despre mine...

ESET NOD32 Antivirus 4 for Linux desktop Most Linux users may claim that they can never fall prey to viruses, Trojans, worms, spyware, phishing and other Internet attacks; however, the reality is different. Linux is no harder to break into than a Microsoft Windows operating system. Even though the Linux platform may not be targeted directly, it can act as a malware carrier and cause serious damage to Windows-based systems in the network. Therefore it is vitally important that every single endpoint user within a network uses an antivirus solution providing this multiplatform protection. ESET NOD32 Antivirus 4 for Linux fulfils this task. ESET’s solution for the Linux desktop employs the award winning ThreatSense® scanning engine. Utilizing advanced heuristic techniques, ThreatSense® provides industry-leading protection against yet unknown threats. Additionally, the sophisticated generic detection method resembling that of DNA profiling is applied to intercept mutations of already existing infiltrations across all platforms.
