Apparently some @xs4all fiber connections in Amsterdam and Sassenheim had a few minutes downtime last night

Posted by jpluimers on 2017/08/01

Uptime robot (free for 50 monitors every 5 minutes) is cool:

These are xs4all fiber connections in Amsterdam and Sassenheim. Despite not mentioned on the xs4all status page [WayBackXS4ALL | Storingen en werkzaamheden, apparently there was some fiber down time in both places.

The HeldenVanNu fiber connection in Amsterdam was doing fine at that time; those downtimes below were planned on my side:

Microsoft Research’s manual memory management for .NET: exactly one owner which provides shields for accessing the objects

Posted by jpluimers on 2017/08/01

A very interesting piece of research, in which I see a very familiar concept of single owners and I new concept of them providing shields for accessing the manually managed memory. I do miss mentions of Anders Hejlsberg, Chuck (Charles) Jazdzewski, or others that lay the foundation of ownership in the [WayBackTComponent Branch.

Microsoft Research’s manual memory management for .NET: https://www.microsoft.com/en-us/research/wp-content/uploads/2017/07/snowflake-extended.pdf

Interesting concept of manual but safe memory management with exactly one owner of an object at any given moment and shields that prevent an object’s destruction while it’s still in use by other threads.

Some potential anti-virus and -malware tools for OpenSuSE Tumbleweed

Posted by jpluimers on 2017/07/31

I could not find many potential anti-virus and -malware tools for OpenSuSE Tumbleweed despite they would be useful not only for non-Linux clients like Windows and Mac OS X.

These I found:

rsync z-lib compression segmentation fault? WTF!

Posted by jpluimers on 2017/07/27

Not sure why without the -z compression switch this succeeds:

There is a way to convert ‘array of const’ (open array) to TValue: Asbjørn Heid found one.

Posted by jpluimers on 2017/07/27

Brilliant solution by Asbjørn Heid:

So the solution I came up with is to use the observation that the “array of const” is “array of TVarRec”, and that “array of TVarRec” is passed as as two arguments: a pointer to the data and the length of the array (or rather, the highest index in the array).
