Another DC2N5-LC DIY kit sold

Having to build your own device might put most people off, but this little device is quite simple to assemble and yet another kit is gone🙂

C2NEmu: Linux client tested too

I managed to test the Linux client of C2NEmu too, with successful results!

$ sudo ./c2nemu-play /dev/ttyACM0 Gianna.tap 
C2NEmu play utility, rel 1.2 - (C) 2016 Luigi Di Fraia
Communicates with a C2NEmu device to play TAP files

Buffer time=3:42 Success condition received from /dev/ttyACM0

The TAP file I played back was dumped by DC2N5-LC and the resulting DMP file was 100% recognized in TAPClean with all check byte checks passing🙂

Header test : PASS [Sig: OK] [Ver: OK] [Siz: OK] 
Recognition test : PASS [771763 of 771763 bytes accounted for] [100%] 
Checksum test : PASS [7 of 7 checksummed files OK] 
Read test : PASS [0 Errors]

I guess the security breach at Libero Mail/Italiaonline was more than just stealing password digests

Earlier this month my email provider, Libero Mail (part of Italiaonline), sent out an email to their users advising that the email account DB had been compromised and password digests stolen. They advised that for security reasons users should change their passwords but that only the secure hashed version of passwords had been stolen, which they contend is quite hard to brute-force.

Well, guess what? I have had reports today from people saying that somebody claiming to be “Luigi Di Fraia” is sending out malicious emails to my contacts. Obviously they are not sending emails from my own email account but from ad-hoc/spamming accounts all over the place.
I guess hackers were able to steal personal information (such as name and phone book) during their attack to Libero Mail, and not just the password digest as advised, or even set up a back-door for further illegal activity.

Stay vigilant people! Double check the sender if you get unsolicited emails apparently from me: as you know, I am not the kind of person sending out emails along the lines of “check out this fantastic stuff at the following link”…

C2NEmu update

I decided to provide a simpler approach to firmware updates in C2NEmu compared to DC2N4-LC, despite C2NEmu is a really low-cost device itself. Firmware updates can now be carried out without opening the enclosure of the device.

As I felt quite inspired by the change in C2NEmu I decided to do the same change in DC2N4-LC. Therefore, despite the latter being sold out, its users can get a new version of the firmware for updating their devices so that if new versions of the firmware become available then they can update without any need to open the DC2N4-LC enclosure.

Happy days🙂

C2NEmu update

I’ve been working a bit on the C2NEmu TAP playback PC client today, adding a time mark  for buffered data in order to give some feedback to users where the playback is.
Here’s an example of the output:

C2NEmu play utility, rel 1.2 - (C) 2016 Luigi Di Fraia
Communicates with a C2NEmu device to play TAP files

Buffer time=1:11

This is one step towards the support for starting playback from any point within the TAP file and eventually for supporting the index file that facilitates rewind/fast forward operations with multi-file TAP files.

Stay tuned as this one little device is only getting cooler! BTW, only 10 will be available at an estimated price of 8GBP + shipping🙂

C2NEmu video

As I finally unpacked the Commodore 64 I bought on eBay to replace my previous one, I thought to make a video of the TAP playback feature in C2NEmu. Here it is:

DC2N5-LC video update

I made an updated video on the dumping process in DC2N5-LC that illustrates the current interface and set of features. Enjoy!
