Recovering deleted pictures from SD memory card

Andrej Dundović — Mon, 10 Aug 2020 09:09:16 GMT

It finally happened! I unintentionally deleted all pictures that I took in a month time from my camera's SD memory cards without downloading them first. After the first shock and disbelief, I remembered that deleting them usually means they are just "marked" for overwriting and that they are still there, but not enlisted in the memory card's filesystem.

Luckily, there are helpful free (free as in speech) tools that helped me to recover all of the pictures.

Headless Installation of CentOS 7 on PC Engines APU2C4

After giving up of running Raspberry Pi as my home server due to its instability and poor performance in cases relevant for me, I was looking for another solution which would also be reasonable priced, yet which would provide stability and strengths in typical home server tasks. Under these tasks I count a backup facility (NAS, Network-attached storage), multimedia server (photos and music), services for simple automation projects and so on. Then I heard some stories about the incredible robustness of ALIX machines which work in inaccessible mountain areas for years and years without problems. The prices of those devices are also about right (~150 euros) and they are based on AMD's embedded CPUs, x86_64 which means running standard GNU/Linux distributions without restrictions. Therefore, I bought one. PC Engines ALIX APU2C4: 4-core 1 GHz CPU (AMD GX-412TC), 4 GB RAM, mSATA SSD, ... from Varia-store.com. Just to mention that the power consumption of the device is ridiculously low - only 6-12 watts.

Kako je slobodan softver izgubio bitku

Trideset i jednu godinu nakon manifesta za slobodan softver, kojeg je Richard Stallman objavio pod naslovom "GNU Manifesto" i time postavio ideološki kamen temeljac pokretu za slobodan softver, može se reći da situacija nikad nije izgledala gore iz perspektive osnovnih ciljeva slobodnog softvera. Slobodan softver je osmišljen s nakanom da obrani slobodu korisnika računala, a 2016. godine korisnici su daleko veći robovi “svojih” mašina i mobitela nego ikad prije.

Zašto slobodan softver?

Ovaj portal okuplja zajednicu računalnih entuzijasta i, reklo bi se, ljubitelja slobodnog softvera (u što spada i GNU/Linux), no dijele li članovi ove zajednice razloge zašto koriste slobodan softver? Pokazalo se u mnogo rasprava da ne...
