"perfectly fine" does not depend on the processor alone, it depends on the compiler. A compiler for x86 can assume dereferencing a NULL pointer is undefined behavior, and optimize your code in ways you perhaps didn't expect.

There are 2 separate, unrelated issues (but described in the same advisory from Juniper). One is they found code that shouldn't be there, allowing remoe ssh login to attackers. The other is weaknesses in Dual_EC.

Yes, it runs in the kernel on Plan 9. And sure, these days there's various optimzation using shared memory for a lot of the gfx or going via OpenGL when using X11. I'm just saying unixes have done it a similar way to Plan 9 since

Note that 2.0 still can be used with GTK. I'm a daily wireshark user and had to switch back to the GTK version - the Qt version is currently incredible buggy - at least on Windows.

A lot of drawing on linux already goes over a "file", a PF_UNIX socket from the application to the X server - with the added penalty of making an additional round trip to the kernel, whilst on Plan 9 you just go directly to the ke

Fair point. I believe you can use the Export-Clixml/Import-Clixml or ConvertTo-Xml/ConfertFrom-Xml for doing just that.

What comes to mind by 4), is "tee", which powershell also has - but that's perhaps not what you want/mean ?

That sounds so little. Just having two 50W lightbulbs shining 24x7 would be slightly more than that in a year.

"go oracle" is right there with "go build" etc, an official tool that shouldn't change any more than the other tools that's part of the Go distribution.

The alternative is pretty much only online forums. Which imo. doesn't offer a lot of advantages, and most forum software is exceptionally bad (though yes, a few new and nicer ones are coming along)

This isn't the actual IS report though, it's a report by the Institute for the Study of War on the IS report.

This is also how most embedded applications utilizing an OS also works these days. The OS is a library, you link in whatever you need from the OS + compile time configuration of OS features etc. + link in whatever you need for your applicat

Hopefully the pilot made it though as a parachute was observed - http://i2.cdn.turner.com/cnnnext/dam/assets/151124102631-rus... (from this article: http://edition.cnn.com/2015/11/24

How so - if the radar image is correct, the plane flew over the strip in Turkey twice, giving them quite a bit of time before and after the first pass to give warnings ?

And indeed also very useful for testing. "what happens if we simulate this process being a bit slow" - send it a SIGSTOP. Doing so can simulate a number of other weird cases too as observed from the outside , such as a process tra

Note that these buffers are not only relevant for unread data of the user space application, they also reflect the TCP window size - this means the sending side knows how much room the receiver has at all times , and can throw that much dat

Personally I much rather like the approach Plan 9 took to decomposition vs what SawMill attempted.

Is there any big difference from this vs https://swtch.com/libtask/ , which is a port of much of the same concept from Plan 9 - which again ties back to Go.

No, quite a lot, if not most, firmware these days can be changed. dd-wrt/openwrt etc. is considered firmware.

Pretty much every router/modem people have at home does NAT, and does so for UDP, TCP, ICMP and some do GRE and that's it. And they're not getting updated to NAT any new protocol directly over IP that people come up with.

Note that bufferbloat is a problem regardless of there being many or few TCP connections.

Also - the open source RTEMS kernel is running on a few radios at Mars and elsewhere, including the Curiosity rover.

I'd like to see a breakdown of file types at e.g. imgur.com - I'm guessing more than 0% are bmp images, and there isn't a compelling reason for a browser to not be able to view those.
