Java only has single dynamic dispatch. That means it will use the method of the most specific sub-class, but will not dispatch on the runtime type of the argument, only its compile time type. So something like: for(None n: expreTree.chi

Pretty cheap if it ends up saving the Android ecosystem. Android is maybe using 10% of the functionality in the linux kernel but is paying all the overhead and friction of maintaining a branch for each and every device. I think google wants

While I really like these sort of file systems, I'm not holding my breath. This isn't a simple filesystem project, but plays in the next-gen space ZFS opened up. There will be a lot to do, especially IO scheduling, RAID safety wit

(?) Obviously, but building a bit-by-bit identical compiler output is moderately hard.

I don't get it. This would not increase trust since we can not check if the source actually corresponds to the binary in the processor. It would need to be repeatably build-able with the result matching the signature of the default blo

There are multiple paragraphs on it just above the Leibniz section (ctrl+f infinit). It comes down to, yes infinity (or any permutation (or DAG) of the universe of facts) for some facts. And yes that is not very satisfying. - But I think an

There is a secret OS running inside the CPU that you don't have access to. Only Intel/AMD know whats really inside and it has access to everything in your system. Usually it even interjects itself into the LAN controller listening

Yeah nice try Oracle, MySQL will not gain its community traction back.

That is wonderful. I always dread dealing with build systems, mostly in the C land. Deterministic behaviour, especially in this rigorous fashion, is probably very helpful for much more cases than just trust. This looming assumption that mak

So I assume this means cockroachDB currently (probably) meets its promised consistency levels. How does it compare to the usual default settings of PostgreSQL for example? - I think you get SERIALIZABLE, so the behaviour should be very reas

Also the "surface" the community sees is not very inviting. Bugzilla is horrible to use, browsing it gives you the strong impression it is abandoned. The wiki is also always outdated, or you can't tell. The forums are a nice

Java does not give memory back to the system very quickly per default. This blows up the memory allocated to the jvm considerably. start it with: java -XX:+UseG1GC -XX:MinHeapFreeRatio=5 -XX:MaxHeapFreeRatio=15 -jar ... and the jvm

I have a NUC5i3RYH and you can (I have) set the fan control curve in the bios so that the fan stays off until the CPU reaches 75°C. It is completely silent until you do some gpu/cpu intensive stuff for some time. It is a lot better tha

Well, what happens if you break the signature? - the IME does not start up... - Exactly what we wanted.

Interesting. In light of recent Oracle JavaSE licencing enforcement (MissionControl etc.) this will provide some safety from legal uncertainty. And maybe redHat will also release a JDK6 build for Windows for the poor souls ( cough ) who are

Well defining the java GC as tracing is underspecifying it a bit. Virtually all GCs are non-refcount, AFAIK mostly because touching refcounters all the time destroys memory performance. A tracing GC can do that in a batched and parallel fas

I'm interested in how this was fixed. Is the update an EFI update which disables DMA or does it with IOMMU? Or is the memory just overwritten on boot? I'm also quite surprised they leave the password in memory in multiple location

Same happens with Chrome, when I side-load my own chrome extension. It's really annoying. I assume they just copied this behavior.

I read the article, and the quoted sentence. This is the reason why I find your HN submission title intentionally misleading. It's a cool project, and this deception is entirely unnecessary. Why not claim "FASTER than Dokany"

Super misleading title and benchmark. Why did they not use a RAM Drive for the NTFS test like one of these https://en.wikipedia.org/wiki/List_of_RAM_drive_software#Non... Are there any on-disk filesystem implementation

Sure they are related. But its not black and white, and not an absolute correlation. macOS itself is actually designed in a very modular way if you look at the message based integration of components via XPC and "do one thing" dae

Nice resource. But what I miss most, is a deeper analysis of the different launchd services and agents. - Especially which ones can be disabled and what features will be impacted. It is quite opaque, especially considering the verbose descr
