There seem to be a notion for slimming down things. Less ports and no DVD
(aka secondary HDD bay) bay anymore. Keyboard on newer models is a bit
weird too. F keys row has been combined with media keys and
end/insert/delete/etc keys have very unusual arrangement. But Linux seems
to be still well supported.
I am using T420 which probably won't fit your needs since it's a bit aged
and can't do more than 2 monitors. But I had a chance to use their latest
T450 model for a few days with Linux and it seemed ok with no apparent
issues. It has x3 USB 3.0 ports, VGA + mini DP, 16GB RAM max, matte
display, M.2 SSD slot (don't know if it can be used as boot device), and
the rest of the usual - RJ-45, WiFi, Bluetooth, multicard reader, WWAN
depending on the configuration. No idea about maximum supported monitors
though.

Re: Up-to-date hardware (laptop) recommendations?

[Roman Ovseitsev]

If you need 3 external monitors on top of the internal, without discrete
GPU the only option is a Skylake based laptop. It can pull off up to 5
monitors through HDMI/DP according to the spec. AFAIK older architectures
support only 3 monitors.
However since it just got released only a couple months back, there
probably not that many laptops to choose from yet. If any at all. Mobile
CPUs with better GPU are still not released so most vendors probably
waiting for them.
As far as Linux support for Skylake there are still some issue which you
might want to be aware of if you decide to go down that road:
ACPI doesn't work with some motherboards. Not an issue though if you don't
mind disabling it in the kernel. Graphics drivers work properly only
starting with 4.3 kernel.

As for the laptop, I've been using ThinkPad T 14" line for years and
overall the build quality, Linux support, repairability, and port selection
are rather good. Although I think the latest models have eSATA port removed
and come with only 3 USB ports, but I haven't checked.

Re: Something is injecting malware into my HTTP traffic

Thanks everyone! That explains it then.

It interesting how the cached version is actually slower to download than
the non-cached.
I haven't noticed the speed difference prior to Michael mentioning it, but
now after some random tests the behaviour seems to be consistent with other
sites as well. Too bad not everyone provides secure versions...

 Just speculating, but could it be that your ISP uses a caching

 its cache got corrupted?
 The other ISP case could be explained if it's actually
 upstream/downstream from your ISP, or they share a proxy cache for other
 reasons.

Re: Does anyone use MATE (Gnome 2 fork)?

I've been using it for the last seven months on Fedora and did a few

Stability wise, there shouldn't be any significant problems.
At the moment there is a small number of negligible bugs and one, long
standing, major issue which may or may not affect you (

Development wise, there is only a handful of active developers working on

Re: Blu-Ray and Linux

[Roman Ovseitsev]

Also it's worth mentioning that with streaming services you are getting a
sub-par quality encode compared to Blu-Ray or properly made re-encodes from
torrent trackers.
I suspect this due to using the same default encoding settings for all the
content and ignoring the actual footage nuances.
While for most movies the differences are not that noticeable, there is an
occasional color distortion, smoothed grain, or bit-rate starvation, which
can deteriorate the quality to near dvd levels at times.
But that's nitpicking. Just because of the DRM alone I would avoid any
streaming services.

 TLDR: http://xkcd.com/488/
 Before you pay for any steaming/download, check for subtitle support and
 HDCP enforcement.  /TLDR

 Not all who do business in Israel have licenses to sell all content;
 selection varies by country and is much better in USA than elsewhere.
 http://canistream.it will tell you the options for a given movie/series,
 at least for USA.
 (There are many grey market services proxying you to appear in USA...)

 I've spent a week recently looking for a legal way to buy The Hobbit (in
 California) online (trying to go paper-less  disk-less) with best Linux 
 Android support, resulting in VUDU -- and another week cursing the
 experience :-(

 The worst news is that all legal streaming/downloads come with DRM.
 (Except some indie movies that offer DRM free downloads, especially if you
 kickstarted them.)

 Most if not all use Adobe Flash for DRM, whose Linux support is
 deteriorating - Adobe no longer updates Flash for Linux, and Chrome has
 it's own fork...

 There is a very annoying tendency to limit resolution by platform.  Many
 only allow DVD quality on PCs and restrict HD quality to locked down
 devices such as roku box/stick, xbox, Android/iOS etc...
 VUDU were one of the few to offer 1080p to PCs.  However, IIRC I only got
 480p quality on Linux because HD is also conditioned on the OS reporting
 end-to-end HDCP to the monitor, which AFAIK Linux doesn't even have an API
 for :-(  I don't remember for sure if this happened to me on VUDU or I read
 about it wrt. other services but in any case HDCP enforcement is a crucial
 point to check before paying for HD on Linux!
 [
 http://blog.linuxacademy.com/linux/unplugged-replace-your-cable-provider-with-linux-enabled-media/reports
  HDCP does exist on Linux, but only with binary bulk nvidia/ATI
 drivers, to WINE apps.  I don't call that Linux...]

 Aside: Netflix also limit by ISP: the highest quality is reserved to ISPs
 that peer with them.  Not sure if they're the good or evil guys here, but
 smells suspicious on net neutrality grounds...  (they're also annoying in
 limiting by bandwidth - no (reliable) support for pre-buffering the whole
 movie in HD on a slow connection, AFAIK).

 In any case I ended up in windows because I sentimentally felt I want to
 own the whole movie on hard disk, and VUDU only offer a downloading app
 for windows.
 Mind you, it's still DRM'd, keyed per machine, stored in some opaque cache
 folder (which I find offensive for 9GB, on general principles).  The player
 is as limited as the in-browser streaming player.  And it kept
 stucking/crashing at a particular spot - I guess the download was corrupted
 (and there is no Verify Data like with torrents - you can only delete and
 re-download the whole file).
 Streaming OTOH was flawless (15Mbps cable)!
 The only annoyance with streaming is re-buffering after seeking, even 10
 seconds back (dear Adobe, or whoever I should hate for this: I have enough
 RAM to retain the last hour of the movie).

 So the only reasons to download are slow connection and watching offline.
 

Re: [OT] Troubleshooting Bezeq Int'l problems

[Roman Ovseitsev]

I had the same problem on Netvision a couple of months ago - files seemed
to miss a few kB after what appeared to be a successful download according
to firefox. Didn't encountered any error pages though. This happened a lot
with Eclipse tar.gz from different mirrors and some other smaller archives.

  This is not directly related to Linux but the problem is also occurring
 on my Linux machines.  Since people here seem to be very knowledgeable
 about how to diagnose and document problems with ISPs I am turning to your
 collective wisdom for some help.

 We have been using Bezeq Int'l as our ISP for years (ever since Actcom was
 bought out).  For the most part we have been satisfied even if the Linux
 support in the early years was not the best.  We are now connected with a
 20Mb DSL connection.  Recently I have noticed a problem with downloading
 certain zip file that the zip files end up truncated.  I.e. rather than
 downloading a zip file of 1.2 MB the download completes successfully but
 the zip file will only be 800 KB and is obviously not usable.  This does
 not happen on all zip files and it does not seem to be connected to a
 particular size of zip file (i.e. larger zip files will work sometimes).  I
 have not been able to pin point a particular characteristic of the zip file
 that causes it to fail.  Windows XP, Windows 7 and Ubuntu all encounter the
 same problem.  However, if I connect my laptop via my phone's 3G network I
 am able to download the zip file without a problem.

 A second symptom that has come up recently is that when I have clicked on
 some links, instead of going to the requested site I am shown an error page
 from Bezeq Int'l saying that this site is dangerous and I cannot go there.
 If I hit the back button and try again I am able to get to the site without
 a problem.

 Putting these two items together I have come to the theory that Bezeq
 Int'l has updated their firewalls / anti virus software which is somehow
 causing both of these issues.

 Has anyone else using Bezeq Int'l encountered similar problems?  Other
 than just calling and complaining are there any tools that I can use to
 further trouble shoot the problem?  If the support people say it is not
 their problem I would like to have as much support as possible to force
 them to deal with the issue.

 Hi,

 I know it is not directly Linux related, but hey, I am using it with
 Asterisk on Linux! ;-)

 I have got an Sipura SPA-3000 VoIP adapter and want to use it with Bezeq
 for calling out.
 For some reason when I dial dialtones on the phone, Bezeq does not
 recognize them properly and makes mistakes in recognizing them.

 It is notable, that if during the call through the SPA-3000 I pick up
 another phone connected to the same Bezeq line directly (using splitter),
 and continue to dial the desired number on the SPA-3000 connected handset,
 the dialed number is recognized properly by Bezeq.

 I guess that the factory-default settings of SPA-3000 for dialtones is not
 suitable for Israel. At the SIP-3000 I have following settings (not that I
 am sure what they mean):

 PSTN Line - DTMF Tx Method: Auto
 Regional-FXS Port Impedance: 600

 Can someone suggest me the ways to make the SPA-3000 to dial out properly?
