To add a little bit: the reason for that (or at least one of them) is strict aliasing rules: If the compiler had to assume that a write to an int* might change the value of a double&, that’ll cause it to avoid some optimization and ma

Or even better: turn off the device. Cracking cold/BFU (before first unlock) devices is not supported in many cases by tools like Cellebrite [1]. [1] https://discuss.privacyguides.net/t/updated-cellebrite-iphon...

No idea why the downvotes, these are valid points. I still don’t fully agree with it: 1. There are alternatives to nvidia: these 3 companies are probably developing their own alternative to NVIDIA, at some point they will switch to their so

According to nvidia’s 2025 annual report [1], 34% of their sales for 2025 comes from just 3 customers. Additionally, they mentioned that customers can cancel purchases with little to no penalty and notice [2]. This is not unique for hardwar

What is up with the name? Edit: Kinkora implies that it has something to do with kinks, at least that was my first impression. My guess is that it means something in another language, but maybe this is not a good first association that you

I think that reading all of the information from the SSD should “recharge” it in most cases. The SSD controller should detect any bit flips and be able to correct them. However, this is implementation detail in the SSD FW. For Linux UBI dev

Also, FYI for the one person here who uses raw nand flash: run ubihealthd ( https://lwn.net/Articles/663751/ ). It will trigger reads in random areas in flash, and try ti correct any errors found. Without it, the sa

Hopefully it will make Qualcomm behave more like Arduino and not the opposite. Qualcomm is one of the worse companies I have had the pleasure to work with. Their support model is hellish and they provide very little information and documen

Tie that chip to a beamformer (silicon labs have a few) and you have a phased array radar, which is a radar that does not move at all (pretty cool in my opinion) Also, 15usd is not cheap for this kind of chip. You can buy a full wifi 7 rf&#

I think that while data is a major point here, in my opinion, these are the reasons apps are preferred by developers: 1. Persistence: while websites are very easy to close, deleting an app is much more difficult and usually requires pressin

The article is a bit strange. While GPS can be used to receive accurate timing (phase correction once per second), for gps less navigation, even a picosecond accurate atomic clock wont really give any additional benefit compared to a wirst

In my experience in two HW companies that developed their own ASICs (one as a startup and one as a publicity traded company), we never developed any chip fully by ourself. In all of the cases there was another large company who helped to ma

Not sure i am following, what problem your product is trying to solve? helping to write tests/run the tests/just organizing tests as a part of the CI pipeline? How is it different than just running tests? (Or is it the platform to

From my experience, the biggest footgun with shared_ptr and multi threading is actually destruction. It is very hard to understand which thread will call the destructor (which is by definition a non-thread-safe operation), and whether a lam

For the first issue: I understand. Thanks. As for the second, There is no shell=True for me in the demo but it is present in the code you sent. So maybe it is just a bug in the presentation somewhere.

Actually, in its root it is based on simd and prefetching. In short, each part of the packet processing graph is a node. It receives a vector of packets (represented as a vector of packet indexes), then the output is one or more vectors, e

I have been developing a product that uses vpp in production for a few years now. It is very cool to see how much you can squeeze out of cheap low power CPUs. You can easily handle tens of gbits in iMIX with a a few ARM cortex A72s. Vpp has

I looked into that. Basically a GitHub action that goes over all of the prs that marked as "automerge" and updates them to master. It is not a perfect solution, but it works perfectly well for our monorepo.

It is only available for enterprise (which is unreasonably expensive: 21usd vs 4usd per month per seat). We asked our devops to develop something similar using our existing ci infra, took them a few days.
