  1. Up. Ma intereseaza in special conturi de instagram cu followeri romani (>100).
  2. Ca tot se discuta despre certificari de security.
  3. Pe partea de defensive ce certificari ar fi (in afara de CompTIA CySA+) ?
  4. Ceva interesant legat tot de code review: NASA coding standards, defensive programming and reliability

    schimb telefon

    Merge, dar e nevoie sa fie exact acelasi model de telefon adica din aceeasi serie de productie. Chiar daca e acelasi model daca e un telefon dintr-o serie mai noua sau mai veche posibil ca imaginea Android din el sa fie semnata cu alte chei. Oricum iti trebuie cunostinte despre cum poti sa conectezi fizic un debugger la telefon. Ca pasi ar fi: 1. Conectezi un debugger fizic la telefon (de cele mai multe ori obtii o conexiune seriala); 2. Copiezi imaginea (folosesti dd if ....) pe sdcard; 3. Incerci sa scrii imaginea pe celalalt telefon sau sa bootezi direct de pe sdcard.

    COVID-19

    Eu nu inteleg de ce nu se impune obligatoriu masca timp de o luna atat in spatii deschise cat si inchise. Bai frate, haide sa vedem daca intr-o luna avand toata lumea masca o sa fie sau nu o schimbare in rata de transmitere. Citisem ca in timpul pandemiei de gripa spaniola toti erau obligati sa poarta masca, nu ca acum... Da-o'ncolo de treaba, daca se poarta o luna de zile masca nu e niciun capat de lume. Si unde sunt amenzile ? Adica tot ce vedem sunt "avertismente verbale", mi se pare ca lucrurile sunt tratate cu superficialitate.
  7. Eu am vazut un caz similar in sisteme embedded: - stick USB normal, nou, fara nicio problema era introdus intr-un sistem, iar atunci cand se facea scrierea pe el erau afectate anumite block-uri (nu stiu exact cum si in ce fel); - daca introduceai acel stick USB cu date corupte in acelasi sistem sau intr-un alt sistem de acelasi tip genera un kernel panic instant, adica sistemul isi dadea reboot in loop cat timp era stick-ul conectat. Isi revenea doar dupa ce faceai remove la stick. Nu erau fisiere de update ci fisiere multimedia pe stick-ul respectiv. Tin minte ca problema era la un codec, la o metoda prin care se extrageau informatii dintr-un fisier video.

    COVID-19

    Am citit ca tratamentul cu sange ce are deja anticorpi a fost folosit si in 1918, pentru gripa spaniola.
  9. M-ar interesa sa cumpar conturi instagram/facebook cu followeri romani. Astept oferte pe PM.
  10. Nu a fost inchis scenefz ?!
  11. HAAAAAAAAAAAAAAA HAAAAAAAAAAAAAAAAAAAAA HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
  12. Dar este un calculator cuantic pur sau ceva pseudo-cuantic ?
  13. :))) De ce sa nu intrebi de salariu ? Nu mai bine stii de la inceput cum stau lucrurile fara a pierde timp atat tu cat si firma cu procesul de recrutare care uneori poate sa dureze cateva saptamani ? Asta in cazul in care ai o anumita experienta in spate. Pentru juniori e o alta discutie. Daca esti la inceput poate e bine sa faci unele compromisuri financiare pt o scurta perioada de timp pentru a acumula anumite cunostinte.

  15. The best programming advice I ever got came to me early in my career while I was working on a system that I simultaneously loved and hated. The cool part of that system was that we were doing computer aided design – think Adobe Illustrator, but for engineers. In those days CAD, with it's interactive graphics was the highest of high tech. The thing I hated was that it was slow, painfully slow: You would sit there and watch the picture appear line by painful line. A simple drawing would take tens of seconds, while displaying something complicated was an opportunity to get coffee. The performance of that system was horrendous even by the standards of the primitive computers we had back then, which is saying something. What was a hacker to do? What would you do? What I did was to dig into the code. Even though the graphics were not my assigned area, I spent some evenings and weekends happily hacking away, trying to see why things were so slow. It didn't take me long to find the problem: When you kicked off that system, you actually started two processes. One process was the CAD system proper, while the second process did all of the drawing. The two programs talked to each other over a socket-like network connection. Apparently the programmer behind the graphics subsystem had fallen in love with client/server style programs and had cooked up one of his own in our CAD system. The rub was that since we were running on such primitive hardware, squeezing all of the drawing down a narrow socket was costing us an order of magnitude in performance, a cost that we were paying for no good reason. I spent the next weekend hacking together a version of the system that packaged everything in a single process. The difference was dramatic. Simple pictures now drew more or less instantaneously while more complex ones would only take one sip of coffee to finish. Monday morning I demo'ed my hacked up version over and over: First to my boss and then to my boss's boss and then to his boss and then to a whole assortment of higher ups. And then all Hell broke lose. Many of those boss's boss's bosses were seriously pissed at me, though no one could or would articulate exactly why. Some of my co-workers started treating me like I had contracted an infectious disease. Slowly, I figured out that I had jumped into the middle of some complex interdepartmental power struggle. In my own clueless way I hadn't sped up the graphics so much as I had supplied a war winning weapon to one organizational faction and the other factions were not happy. Eventually, grudgingly, they did away with the second process along with the socket and we got our faster graphics. Nevertheless elation seemed thin on the ground. That was when the Biggest Boss of All asked me to stop by his office and gave me a key bit of advice. With the door safely closed he turned, looked me square in the eye and said: "In the future, stay the Hell out of other people's code." Actually it was terrible advice, advice that I've gone out of my way to ignore in the years since. But those words were valuable nevertheless, and I've gone back to them time and again. Every time some annoying new-hire comes to me with a dumb idea that is obviously not going to work, Stay the Hell out of other people's code plays back in my head and I listen harder. Every time some other engineer has an opinion about my code, I remember what I thought of the idea that you should mind your own technical business and I try to disengage my ego. In later years, as I found myself building and managing software teams, I've realized that there were probably a dozen programmers on that ancient project who knew why the system was so slow and how to fix it. They knew, but they kept it to themselves because in that organization, there were some things that were more important than making the system better. In the future, stay the Hell out of other people's code. assumes there will be a future. But the best way to have a future is to be part of a team that values progress over politics, ideas over territory and initiative over decorum.

    High School

    Da, dar mai sus ai zis ca ai terminat mate-info-intensiv. Daca terminai filologia, mai invatai in 6 luni ? Probabil nici nu auzeai termeni precum "CCNA", "Algoritmica", "Programare", decat in cazul in care aveai o pasiune pentru domeniu. Dar sa fim seriosi, numarul persoanelor pasionate este foarte mic... iar in ziua de azi multi se duc catre IT pentru ca isi pot gasi relativ repede de munca si primesc un salariu decent.

    High School

    Sounds good, doesn't work. Un liceu de prestigiu iti ofera acces la diverse concursuri, activitati si... ai mai multe sanse sa iei bacul cu o nota mare. In teorie la liceele de prestigiu sunt si cei mai buni profesori/elevi.

    Daca te duci la un liceu militar pt ca asta e visul parintilor tai o sa regreti mai tarziu. Da, in momentul de fata in Romania profilul real la liceu e singurul care iti ofera un background astfel incat dupa terminarea lui sa ai toate optiunile disponibile privind facultatea.
  20. De asta trebuiesc certificate sistemele sa indeplineasca anumite standarde. Chiar daca modifica cineva 2-3 linii de cod, inainte sa ajunga in productie sistemul, el trebuie recertificat.
