64DD is something we would like to support fully eventually. Since the cart code is all written in C (+PIO), it opens up a lot of flexibility for implementations like this. Not everyone is well-versed in verilog/HDL, but there's p

The project has just started. I made the proof of concept, and now I am building the full project. There's tons of work left to do. We are building a small community around this and any help is appreciated, be it programming, testing o

You could swap the flash to 16MB, or use a third party (almost) pin compatible clone with 16MB flash if you really want. I implemented a very simple compression scheme as well so you can load 16MB ROMs that compress to a few kilobytes less

Aha! Makes sense. The docs are usually great for git, but it wasn't clear to me that the args were passed on to git format-patch, where the -v parameter indeed is properly documented.

In the e-mail reply that you get when following the guide you get something to copy paste that looks like this: git send-email -v2 ... I tried to find documentation regarding the -v[0-9]+ parameter but couldn't find it at all

Great guide but there seems to be a typo/mistake regarding how to save the smtp password in step 2/gmail: should use sendemail.smtpPass instead of the non existing sendemail.password.

Thanks for your quick reply! This sounds like a good solution. I was trying to solve this problem on my own as well and ended up making a minimal kernel+afl image that I then boot multiple times using deduplication features in order to save

This is awesome! I wish you all the best and hope that this takes off. I am curious about how you use AFL under the hood - how do you scale? Do you use a shared kernel and run a worker process for each physical core, or do you do some virtu

Nice explanation! I think you accidentally made a formatting typo: "each cell tower can provide 2043/2 120 Mbps", the 4 is probably surrounded by asterisks.

Thanks, didn’t know about this tool.

I miss this. I'm working with embedded C and we always end up nitpicking formatting in review. Using checkpatch helps, but is there something like Prettier for C? I'm aware of the tool called indent but it seems a bit arcane.

Found this blog with someone who bought an FPGA devkit[1] for £260 and managed to boot Linux on it[2]. [1] https://rwmj.wordpress.com/2016/07/25/risc-v-on-an-fpga-pt-1... [2] https://rwmj.wordpress

As far as I know, only the Freedom E310[1] chip is available for purchase by normal consumers. It's a microcontroller and only has 16kB of RAM so it's probably not really what you are looking for. But if you are still interested i

Can confirm that the privilege escalation works on OnePlus 2 as well.

Sure, but this makes it possible to dump the firmware for further analysis. I think that's the big news here. Think we might read about a few new bugs over the coming months. Also it might be possible to flash new firmware (to lock it

Looks great! Would be cool to plot it over time as well.

The zipcpu blog posts never ceases to amaze me, the content is so good. As a sw developer who plays around in verilog on my free time, the posts are extremely helpful to me. I just want to tip my hat to the author(s?), thanks!

With clang you can enable run time UB checks using the -fsanitize=undefined flag[0]. But in this case, the sanitizer doesn't detect undefined behavior. I tried to build the example (and changing the system to an echo) using "clang

As a non-american I have to ask: why sign up for new credit cards all the time?

I believe this[1] is the patch that fixes this bug. I tried to reproduce the behavior but couldn't succeed. Maybe I was doing something wrong. Would really appreciate it if someone here could show a test case where this matters. [1] h

This is an important point. It surprises me that many non-US companies use slack for their internal and secret communication.

Which compiler would you recommend using instead?

by kbeckmann 10y ago
Not a silly question at all. I would also like to know this. Would be a fun way to play around with assembly without the need of a tool chain etc. Maybe even on your phone while on the train. If this doesn't exist already, I'd be

What are you using instead, can you recommend a nice alternative?

While on the subject, what is the difference between file:/path/to/file and file:///path/to/file ? Usually I only see the latter being used.

Would love to read Fabien Sanglard's review of it in a couple of months...

A good cover letter tells more about the person and not just the cold facts. What motivates the person, details about side projects etc.
