157 files while asking the user to select which one to use if more than
158 one exist. Once a file is identified, the PDF is associated with the
159 file and uploaded, using the title extracted from the PDF itself. The
160 process is fairly similar to visiting the archive, opening a cabinet,
161 locating a file and storing a piece of paper in the archive. Here is

>Over the years, administrating thousand of NFS mounting linux

221 was experiencing NFS hang. If you try to use
<tt

222 file or directory affected by the hang, the process (and possibly the
223 shell) will hang too. So you want to be able to detect this without
224 risking the detection process getting stuck too. It has not been
225 obvious how to do this. When the hang has lasted a while, it is
226 possible to find messages like these in dmesg:

248 I assume this will not show lazy umounted NFS points, nor NFS mount
249 points in a different process context (ie with a different filesystem

>The key number to look at is the third number in the per-op list.
295 It is the number of NFS timeouts experiences per file system
296 operation. Here
22 write timeouts and
5 access timeouts. If these
297 numbers are increasing, I believe the machine is experiencing NFS
298 hang. Unfortunately the timeout value do not start to increase right
299 away. The NFS operations need to time out first, and this can take a
300 while. The exact timeout value depend on the setup. For example the
301 defaults for TCP and UDP mount points are quite different, and the
302 timeout value is affected by the soft, hard, timeo and retrans NFS
303 mount options.

331 Well, doh, if it is one thing the confirmations from Snowden
332 documented, it is that the entire population in USA is wiretapped, one
333 way or another. Of course the president candidates were wiretapped,
334 alongside the senators, judges and the rest of the people in USA.

336 <p

337 Justice to go public rejecting the claims that Donald Trump was
338 wiretapped illegally. I fail to see the relevance, given that I am

397 USB dongle for generating entropy created by Bdale Garbee and Keith
398 Packard. Yesterday it arrived, and I am very happy to report that it
399 work great! According to its designers, to get it to work out of the
400 box, you need the Linux kernel version
4.1 or later. I tested on a
401 Debian Stretch machine (kernel version
4.9), and there it worked just
402 fine, increasing the available entropy very quickly. I wrote a small
403 test oneliner to test. It first print the current entropy level,
404 drain /dev/random, and then print the entropy level for five seconds.
405 Here is the situation without the ChaosKey inserted:

426 <p

">The
537 case at hand
</a
> is that the Norwegian National Authority for
538 Investigation and Prosecution of Economic and Environmental Crime (aka
539 Økokrim) decided on their own, to seize a DNS domain early last
540 year, without following
541 <a href=
"https://www.norid.no/no/regelverk/navnepolitikk/#link12
">the
542 official policy of the Norwegian DNS authority
</a
> which require a
543 court decision. The web site in question was a site covering Popcorn
544 Time. And Popcorn Time is the name of a technology with both legal
545 and illegal applications. Popcorn Time is a client combining
546 searching a Bittorrent directory available on the Internet with
547 downloading/distribute content via Bittorrent and playing the
548 downloaded content on screen. It can be used illegally if it is used
549 to distribute content against the will of the right holder, but it can
550 also be used legally to play a lot of content, for example the
552 <a href=
"https://archive.org/details/movies
">available from the
553 Internet Archive
</a
> or the collection
554 <a href=
"http://vodo.net/films/

559 <p
>I did not quite know what to expect from a day in court. The
560 government held on to their version of the story and we held on to
561 ours, and I hope the judge is able to make sense of it all. We will
562 know in two weeks time. Unfortunately I do not have high hopes, as
563 the Government have the upper hand here with more knowledge about the
564 case, better training in handling criminal law and in general higher
565 standing in the courts than fairly unknown DNS registrar and member
566 associations. It is expensive to be right also in Norway. So far the
567 case have cost more than NOK
70 000,-. To help fund the case, NUUG
568 and EFN have asked for donations, and managed to collect around NOK
25
569 000,- so far. Given the presentation from the Government, I expect
570 the government to appeal if the case go our way. And if the case do
571 not go our way, I hope we have enough funding to appeal.
</p

573 <p
>From the other side came two people from Økokrim. On the benches,
574 appearing to be part of the group from the government were two people
575 from the Simonsen Vogt Wiik lawyer office, and three others I am not
576 quite sure who was. Økokrim had proposed to present two witnesses
577 from The Motion Picture Association, but this was rejected because
578 they did not speak Norwegian and it was a bit late to bring in a
579 translator, but perhaps the two from MPA were present anyway. All
580 seven appeared to know each other. Good to see the case is take
583 <p
>If you, like me, believe the courts should be involved before a DNS
584 domain is hijacked by the government, or you believe the Popcorn Time
585 technology have a lot of useful and legal applications, I suggest you
586 too

589 unlikely), the rest will be spend promoting free software, open
590 standards and unix-like operating systems in Norway, so no matter what
591 happens the money will be put to good use.
