I wish they would at least be able to do smaller faster updates for this stuff on Mac OS.

Keep wondering if RUM Indexes [1] will ever get merged for faster and better ranking (TF/IDF). Really would make PG a much more complete text search engine. https://github.com/postgrespro/rum

In all my research mechanical -> electrical -> mechanical double conversion is significantly less efficient than a direct mechanical drivetrain. It seems to come down to about 80% for the best electrical vs >95% for mechanical [1]

I read Diaspora which touches on that as well, I really need to read Permutation City.

Speed of light would just be rule, like cellular automata rules, Planck distance is cell size and the rule is you may only move one cell per frame in any direction. Processing speed doesn't matter to us, it could take a million "y

Not looking for perpetual motion only a compact solid state heat engine on par with others in effciency that would allow a small nuclear battery to work without the steam engine complexity issues. The mars rover uses a RTG that puts out 200

Mirai can't perform better because the fuel cell can't put out enough burst power, it needs a buffer battery as is for acceleration and regenerative braking and the buffer battery isn't big enough either for Tesla like accele

Keep wondering if a smartphone maker will build in a point to point radio system like goTenna [1] or Beartooth [2]. Ideally everyone would agree on a standard and you can just text message / share location with anyone in range and mesh

Prismatic CATL's right? Closer to a pouch than cylindrical 21700's.

The point was you would normally get higher efficiency and spend less money and have higher payload capacity with just a diesel van if your mostly doing highway driving. Was interested in seeing if they did anything special to get efficienc

Seems to be a series hybrid which is unusual. Most hybrids are parallel and connect the engine to the wheels. The electric double conversion of a series is less efficient than a direct mechanical connection especially at highway speeds. Som

Wonder why WebView2 would be any better than Electron? They are both Chromium based and if kept ups to date should be almost identical, would it just be saving disk space and sharing some memory since it would be using a single install of t

Which are what? How does hardware isolation protect against them?
744.
by SigmundA 5y ago
I have concerns about hardware as a security boundary as well, more so lately, as should you I hope and it's much more difficult to patch hardware. Again Midori used SIP's so it was validated in production, right? Projecting worsh

by SigmundA 5y ago
So SIP's don't change any of that except maybe the possibility of formal verification and easier patching of discovered flaws. You get similar guarantees to hardware checks with less overhead thats the point. Either way you'r

by SigmundA 5y ago
SIP are not new, those previous systems you mentioned are a form of them, many shared hardware address space across all processes and relied on the programming language being safe for isolation but they where built in a time when running un

by SigmundA 5y ago
How does hardware isolation solve that issue? SIP's do the same thing...
748.
by SigmundA 5y ago
The GC was written in an unsafe dialect of Sing#, again app code was not allowed to be unsafe which allowed software rather than hardware isolation. Also Midori used SIP's see "Execution Model" here: http://joeduff

by SigmundA 5y ago
Hardware isolation can be exploited due to bugs too and have been quite a bit lately so the alternative doesn't solve that problem. Conflating Java applet security with software isolated processes as implemented in Singularity is not d
