I believe they can't because of the legality, it would remove the secrecy of the warrant. The canary allows a company to imply they got searched without breaching the secrecy. In this case, information got removed, which is not illegal

GCs can be more efficient if you alloc/free memory very often. shared_ptr can be quite slow because of the bookkeeping. It can also help bring more consistent performance, ie. one big malloc instead of millions of small ones.

In the case of curl it can happen if the server did not use Content-Length and the connection gets closed.

by fathyb 4y ago
The point of TFA is preventing piping curl to bash, not preventing from running bash scripts. The problem with piping is that bash will read line by line, keeping the connection open while it runs. If the connection fails for any reason, th

This is pretty much what happened with Darwin from Apple. The kernel and even the bootloader uses .plist files [0] extensively, which are XML-based. I like it. To change the PCI IDs for a driver for example, change the IOKitPersonalities pr

I'm not sure. There was almost no paper trail, no accounting. Testimonies will be used to fill in the blanks and strengthen the case. She'll get a good deal.

It sure is, and there are even more funds and more people working on this today than there were 30 years ago. Breakthroughs have been found recently. People use busses and watch cars win 24h endurance races using this technology, partly tha

Agreed with you on the physics, but I think there is much more progress to be made on the rotor to handle higher RPMs, time will tell. For the F1 experiment, they used magnetic composite materials.

Flywheels should be more efficient. With the current tech for mechanical <=> electrical conversion, a super-capacitor with 100% efficiency would be as efficient as a flywheel with ~65% efficiency for regen braking. The flywheels by GK

by fathyb 4y ago
I think you misunderstood me: I meant flywheels could be used for temporary storage (regen breaking), as a complement to permanent storage (battery), because it is more efficient for regen and handles energy bursts better.

by fathyb 4y ago
As of today the characteristics of flywheels are definitely better for racing and not very useful to consumers. But I believe that they will find a usage if we find a way to miniaturize them enough. Regenerative braking converts mechanical

I used TypeORM and ended up regretting it because of bugs and regressions. I felt that it was unsalvageable. Prisma is from a company so I did not consider it. I found MikroORM and got very interested with. Relations can be resolved directl

I think the entirety of Hotspot is written in C++ [0]? The standard library in the JDK is mostly written in Java, but the VM itself with the GC and JIT code is in C++, which makes sense. If you do not count the standard library as part of t

I support those, and I believe they deserve more: - SerenityOS [0], they do get some donations, but nothing close to the Linux Foundation, Wikipedia, or Mozilla. - MikroORM [1] if you'd like to support an ORM for TypeScript in the back

There is also the I/O, most interaction with disks or NICs are copying twice. We know efficient zero-copy I/O is achievable, it's just that it requires a lot of work for kernel and app developers with a very limited ROI.

I needed to compress a TCP stream [0] for a block-storage project and I've been very impressed with zstd. Combined with io_uring, I'm getting less CPU usage and higher throughput to send and compress data than using socat to send

I did, mostly for Metal-based rendering. It's great if you want to mix Apple's Objective-C APIs with your own C++ code.

It's a POC grant, more money should get unlocked if it succeeds. Smaller grants means more grants and more research (hopefully!).

It feels like Mastodon is limited by the limitations the web (rightfully) added to improve security/restrict third party tracking. A lot of these UX issues could be fixed by having native client apps, where you add servers and the clie

by fathyb 4y ago
It depends how much, where, and when you'd like the data to be sent? Most discrete GPUs cannot access the CPU memory directly, so you need to make a copy through the PCI bus, which can be slow. If you have small chunks of data (mining)

This is a privilege escalation exploit, it gets a root shell from a non-root process. You can get root privileges on macOS using su/sudo.
