Kotlin

Vrea cineva sa se ocupe de Kotlin, un fel de extensie Java care permite si lambda calcul si multe altele....

Fiti totusi avertizati ca versiunile de Kotlin si cele de InteliJ samd au prostul obicei sa traga cu ochiul printre datele utilizatorului. Cel putin pe Linux, la Ubuntu, Kotlin este pus intre programe cu probleme, si este insotit de acest avertisment:

"Aceasta aplicatie va poate accesa toate fisierele si resursele !"

Se gasesc destul de usor cocumentatii:

O mica prezentare despre Kotlin, care se arata ca un fel de limbaj de POO dar si cu functii anonime si cu bibliotece Java, si cu filtre la vectori etc. Vedeti la:

http://zielona-gora-jug.github.io/files/Kotlin-jug.pdf

Ca idee cum arata programele, gasiti cateva exemple aici. 

Dar cartea la care face autorul reclama nu am gasit-o. :(

https://github.com/antoniolg/Kotlin-for-Android-Developers.

Un alt set de exemple este pe GitHub aici:

https://github.com/Apress/learn-kotlin-for-android-development 

Este posibil sa gasiti o editie (periculoasa a cartii - cine stie, poate cu scripturi)

pusa de hackerii de prin Iran sau Iraq. Dat fiind ca volumul apartine altui proprietar, editura care l-a facut nu pot sa vi-l recomand.

Evitati deci adresa:

https://dl.ebooksworld.ir/motoman/Apress.Learn.Kotlin.for.Android.Development..www.EBooksWorld.ir.pdf

Daca o accesati , o accesati pe riscul dvs. real.

S.O. - Sisteme de Operare

 Cateva notite de la intalnirea nr 2. (15 oct)

Linkul la intalnirea 1vedeti aici: https://video4linux.blogspot.com/2020/10/sisteme-de-operare.html Dar sunt doar cateva notite ocazionale.

1) In ultimul moment am mai gasit pentru voi o carte despre Linux:

https://edu.anarcho-copy.org/GNU%20Linux%20-%20Unix-Like/Linux%20Essentials,%202nd%20Edition.pdf

Pare sa contina acele lucruri pe care le predam si noi prin curs si prin laboratoare, dar este in engleza.

2) Un manual in limba romana: manualul distributiei Slackware.

Este incarcat pe grupul Teams. 

3) Un ghid practic: Linux essentials

https://www.asfa.k12.al.us/ourpages/auto/2016/8/10/55689107/A-Practical-Guide-to-Linux-Commands-Editors-and-Shell-Programming-2nd-Edition.pdf

 4) Linux essentials Study Guide (Fedora 21 cel putin ).

https://dl1.newoutlook.it/book/2020/03/LPI-Linux-Essentials-Study-Guide-Exam-010-v1.6-3rd-Edition.pdf 

Revenim la continut si argumente: Discutam despre motive de a folosi Linux.

Ramasesem la pct 5.

[5] Jocurile legale ...

[6] Deoarece pot rula si din vechile aplicatii. 

6.1 Emulatorul Wine. Vedeti site-ul proiectului Wine.

6.2 Mono = platforma .NEt reimplementata pe Linux. DotNet 2 si 4.

[7] Stabilitatea sistemului. Veti reinstala Linux cand veti dori, (la aparitia unei noi editii a distributiei), nu cand aveti un sistem disfunctional. Functionarea este fara defragmentare. Nu consumati timp cu defragmentarea. Avem si drepturi de acces la fisiere.  

[8] Internet si LAN (retea locala).

Linux a fost pregatit pentru integrarea in retele, fie ele locale sau internet. Din start, includea stiva de protocoale TCP/IP. Parca si downloadul este mai rapid. Exista la Linux niste "drivere" /module care fac compresie de date: PPPDeflate si BSD Compression. 

In plus, Linux poate fi transformat in Server.  Linux se poate transforma in fel de fel de servere: ssh, ftp, sftp, asterisk, samba (print sharing/file sharing), dns, dhcp, radio-internet (icecast2 server). Gateway server, proxy server. Router. Bridge. 

Atentie: - folosirea distributiilor vechi, incorect configurate, pornirea de servicii inutile, drepturi de acces exagerate, aplicatii server nerulate in containere. (chrootjail, ..., masini virtuale). 

Atentie: Accesul fizic la masina Linux reduce securitatea la zero, cu exceptia partitiilor criptate.

Amanunte: Mie mi-a placut: Securing Optimizing Linux (Gerhardt Mourani). Acuma se gaseste pe Amazon. 

[9] Discuri hard de adaugat cu usurinta. 

9.1 Un windows era greu de migrat pe un alt HDD.

Un server putea avea nevoie de spatiu de stocare. 

Frumos: Daca un director s-a umplut cu date il pot inlocui cu o ditamai partitia de pe un mediu extern.

Linux foloseste un arbore de fisiere... arbore in care pot exista mai multe partitii vazute ca niste directoare. Vezi montare / mount.

Nu sunteti obligati sa copiati totul pe alt hardware.

9.2 Ce ma fac cand am nevoie de spatiu dar unitatile mele sunt prea mici ?

Sub Linux se poate sa grupezi mai multe HDD / SSD intr-o unitate RAID. 

Inainte de Linux, un RAID, se realiza cu hardware specializat. O placa de controller, la care conectai HDD-urile si un driver ca sa le vezi ca pe o singura unitate. Paralel ATA si la SCSI.

Surpriza: Sub Linux se poate face un RAID, fara hardware suplimentar. 

Concluzie: Raid pe Linux este RAID Software.

Nou: LVM . 

10. Servere posibile. O multime: ....

11. Desktop-urile sau Desktop managerii. 

Dupa tipul de calculator: 

A) KDE, GNOME - interfete desktop puternite

B) LXDE, XFCE, CINAMMON, ..., vezi lectia coresp.

12. Defecte. Hard cu defecte ruleaza uneori.

PLUS:

13. ndiswrapper - adaptor pt cartele de retea cu drivere windows

14. Tablete cu Atom , Tablete X86, care ruleaza Linux. (Linuxium ??)

15. Linux permite sa folosesti imprimate PostScript si PCL 5,6 etc.

16. Similitudinea cu Mac OS. (Ubuntu, cairo-dock ?)

17. Soft audio video: editoare video, audio .etc

18. Este baza androizilor .... Android X86.

ORAR FR

 Orarul de la FR poate fi gasit aici:

Programare functionala - Nu uitati URL-urile acestea

Programare functionala - Nu uitati URL-urile acestea !

1) Haskell.ORG. Poti incerca mici expresii de haskell aici, on-line.

https://www.haskell.org/

2) Haskell Platform

Haskell cu tot cu OpenGL si alte biblioteci. 

https://www.haskell.org/platform/

3) Rezumat de programare functionala

https://wiki.haskell.org/Programare_functionala 

4) Gentle Intro to Haskell, dar in Franceza

https://wiki.haskell.org/wikiupload/5/5e/GentleFR.pdf

5) IDE-ul de Haskell numit Leksah

http://leksah.org/download.html

Qt - Programare multiplatforma si multimedia

Mediul de programare Qt Creator versiunea 5.12.9 pentru Windows se gaseste la aceasta adresa:

Qt Downloads Offline Installer

https://www.qt.io/offline-installers

Desi eu v-as recomanda pentru inceput alte versiuni, cu numar mai mic sau egal cu 5.8.

Mai nou, au inceput sa construiasca o piata de componente, on-line. Ceea ce inseamna ca pentru anumite proiecte,anumite clase de obiecte trebuie sa fie cumparate. :( 

https://marketplace.qt.io/collections/all

Sincer, mie pentru primele lectii de initiere in programarea aceasta multiplatforma parca tot vechiul Qt 4.6 - 4.7 versiunea  de la Nokia imi este aproape de suflet.

 

 

 

Laborator SO 8-oct2020

Invatati sa cititi mesajele sistemului Linux, aratate de comanda dmesg. Folositi caietul de laborator lectia 1 si ascultati raspunsurile si indicatiile de lucru.

Adica dumpingul mesajelor sistemului dvs.

1) Ce distributie este folosita ?   R: Ubuntu. 18.04.

2) Cata memorie are laptopul ? cautati, unele nuclee nu scriu. 8GBytes.

Memory: 7881164K/8162280K available (14339K kernel code, 2379K rwdata, 4928K rodata, 2704K init, 5020K bss, 281116K reserved, 0K cma-reserved)

3) DMA foloseste. da,

4) ACPI ce inseamana ? Power interface, tehnologie pt control al consumului.Dar APIC ?

5) Cate procesoare am ? 4 procesoare. Obs: hypertrading.

6) Frecv procesoarelor ? 2.5 Ghz 

7) Se numeste ?

smpboot: CPU0: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz (family: 0x6, model: 0x8e, stepping: 0x9)

8) Memorie cache ? Vezi caiet pg  3.

64 Kbiti pt cache de instructiuni si tot atat la cache de date.

9) APM = ?  "Advanced" Power Interface = "bunicul" ACPI -ului.

Computerele cu sisteme ACPI nu mai au APM , care nu mai e de mult "advanced."

10) Intreruperea folosita de tastatura ?  R: 1

serio: i8042 KBD port at 0x60,0x64 irq 1

11) Dar mouse-ul de la portul AUX ?

12) Modul UDMA cu care e compatibila interfata  hardul ATA/SATA ? Ce aflati despre UDMA ?

Compatibil UDMA  - invechit.

Permite HDD cu SATA 1. Permite SSD -SATA 3 (nu doi).

[    1.306937] ahci 0000:00:17.0: AHCI 0001.0301 32 slots 2 ports 6 Gbps 0x3 impl SATA mode
[    1.307628] ata1: SATA max UDMA/133 abar m2048@0xdf333000 port 0xdf333100 irq 126
[    1.307630] ata2: SATA max UDMA/133 abar m2048@0xdf333000 port 0xdf333180 irq 126
[    1.623931] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[    1.951990] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)

Concluzie: A meritat sa pun un SSDin loc de HDD.

Sunt computere care au si NVME si SATA - pt unitate suplimentare de stocare.

 13) Ce firma a produs HDD / SSD -ul ? Cautati ata1.

ata1.00: ATA-11: Patriot Burst, SBFM61.3, max UDMA/133

Cool : ii vad partitiile !

 sda: sda1 sda2 sda3 sda4 < sda5 sda6 sda7 sda8 >

 14) Irq-ul primei interfete ... depasita. In trecut : irq14.

Curios ca imi arata:

[    1.307628] ata1: SATA max UDMA/133 abar m2048@0xdf333000 port 0xdf333100 irq 126
[    1.307630] ata2: SATA max UDMA/133 abar m2048@0xdf333000 port 0xdf333180 irq 126

De citit (opt). https://askubuntu.com/questions/1243840/ubuntu-20-04-high-load-on-cpu-because-of-irq-126

15) Periferice similare HDD ?  Cuplate pe interfete similare ?

 ata2.00: ATAPI: HL-DT-ST DVD+/-RW GU90N, A1C1, max UDMA/100

16) Istorie: irq 15. Linux permite sa investighezi tabela de intreruperi.

Au ramas intrebarile 17 - 26.

Nota: Aceste scurte note explicative ramase nu pe tabla ci pe blog, nu tin locul participarii la laborator !
