Ritesh Raj Sarraf: apt-offline 1.7.2 released

I am happy to announce the release of apt-offline 1.7.2. This has turned out in time for the next release of Debian, i.e. Debian Stretch. A long standing cosmetic issue in CLI of the progress bar total item count has been fixed. There are also a bunch of other bug fixes, for which the specifics are present in the git logs. Also, in this release, we've tried to catch-up on the Graphical Interface, adding the GUI equivalent of the features, that were added to apt-offline in the recent past. In 1.7.1, we added the changelog option, and in this release, we've added the GUI equivalent of it. The 'set' command had had many new options. So in this release the 'set' command's GUI has those options added. I hope you like this release. Please test and file bug reports in time so that we have a bug free version for Debian Stretch. Future tasks now will focus on porting the GUI to PyQt5 first and then apt-offline to Python3. Any help is welcome. You can download apt-offline from the github page or the alioth page. For Debian users, the package will show up in the repository soon. PS: What is apt-offline ? 
Description: offline APT package manager
 apt-offline is an Offline APT Package Manager.
 .
 apt-offline can fully update and upgrade an APT based distribution without
 connecting to the network, all of it transparent to APT.
 .
 apt-offline can be used to generate a signature on a machine (with no network).
 This signature contains all download information required for the APT database
 system. This signature file can be used on another machine connected to the
 internet (which need not be a Debian box and can even be running windows) to
 download the updates.
 The downloaded data will contain all updates in a format understood by APT and
 this data can be used by apt-offline to update the non-networked machine.
 .
 apt-offline can also fetch bug reports and make them available offline.

Ritesh Raj Sarraf: GNOME Shell Extensions and Chromium

Most GNOME users may be using one or more extensions for the GNOME Shell. These extensions allow extending functionality for the shell, or modify default behavior, to suit the taste of many users, who may want more than the default. Having flexibility to customize the desktop to ones personal need is a great feature, and the extensions help achieve them. The GNOME Shell Extensions distribution mechanism is primarily through the web. I think they aspire to achieve something similar to Chrome's Web Store. Up till recently, the ability to install those Shell Extensions was a) Through your distribution channel, where your distribution may have packaged some of the extensions. b) Through the Firefox web browser. GNOME Shell Extensions installation from the web, to most of what I'm aware of, until recently, only worked with Firefox browser. With the chrome-gnome-shell package, which is now available in Debian, Debian GNOME users should be able to use the Chromium browser for managing their GNOME Shell Extensions.
  1. Install package chrome-gnome-shell
  2. Open Chromium Browser and go to Web Store
  3. Install Chrome Shell Integration extension for Chromium
    1. .
  4. Point your browser to: https://extensions.gnome.org/local
In future releases, the plan is to automate the installation of the browser extension (step 3), when the package is installed. This feature is Chromium specific and will be achieved using a system-wide chromium browser policy, which can be set/overridden by an administrator.

Ritesh Raj Sarraf: Laptop Mode Tools 1.70

I'm pleased to announce the release of Laptop Mode Tools, version 1.70. This release adds support for AHCI Runtime PM, introduced in Linux 4.6. It also includes many important bug fixes, mostly related to invocation and determination of power states. Changelog: 1.70 - Sat Sep 24 16:51:02 IST 2016
* Deal harder with broken battery states
* On machines with 2+ batteries, determine states from all batteries
* Limit status message logging frequency. Some machines tend to send
ACPI events too often. Thanks Maciej S. Szmigiero
* Try harder to determine power states. As reports have shown, the
power_supply subsystem has had incorrect state reporting on many machines,
for both, BAT and AC.
* Relax conditional events where Laptop Mode Tools should be executed. This
affected for use cases of Laptop being docked and undocked
Thanks Daniel Koch.
* CPU Hotplug settings extended
* Cleanup states for improved Laptop Mode Tools invocation
Thanks: Tomas Janousek
* Align Intel P State default to what the actual driver (intel_pstate.c)
uses
Thanks: George Caswell and Matthew Gabeler-Lee
* Add support for AHCI Runtime PM in module intel-sata-powermgmt
* Many systemd and initscript fixes
* Relax default USB device list. This avoids the long standing issues with
USB devices (mice, keyboard) that mis-behaved during autosuspend Source tarball, Feodra/SUSE RPM Packages available at:
https://github.com/rickysarraf/laptop-mode-tools/releases Debian packages will be available soon in Unstable. Homepage: https://github.com/rickysarraf/laptop-mode-tools/wiki

Ritesh Raj Sarraf: apt-offline 1.7.1 released

I am happy to mention the release of apt-offline, version 1.7.1. This release includes many bug fixes, code cleanups and better integration.
  • Integration with PolicyKit
  • Better integration with apt gpg keyring
  • Resilient to failures when a sub-task errors out
  • New Feature: Changelog
    • This release adds the ability to deal with package changelogs ('set' command option: --generate-changelog) based on what is installed, extract changelog (Currently support with python-apt only) from downloaded packages and display them during installation ('install' command opiton: --skip-changelog, if you want to skip display of changelog)
  • New Option: --apt-backend
    • Users can now opt to choose an apt backend of their choice. Currently support: apt, apt-get (default) and python-apt
Hopefully, there will be one more release, before the release to Stretch. apt-offline can be downloaded from its homepage or from Github page. Update: The PolicyKit integration requires running the apt-offline-gui command with pkexec (screenshot). It also work fine with sudo, su etc.

Ritesh Raj Sarraf: User Mode Linux

Recently, we had the User-Mode Linux suite out of Debian, which included user-mode-linux, user-mode-linux-doc and uml-utilities package. We are happy that we were able to bring it back into the archvie quick, and hope to maintain it active. For many who may not know about UML, here's a discription from its website: 
User-Mode Linux is a safe, secure way of running Linux versions and Linux processes. Run buggy software, experiment with new Linux kernels or distributions, and poke around in the internals of Linux, all without risking your main Linux setup.
User-Mode Linux gives you a virtual machine that may have more hardware and software virtual resources than your actual, physical computer. Disk storage for the virtual machine is entirely contained inside a single file on your physical machine. You can assign your virtual machine only the hardware access you want it to have. With properly limited access, nothing you do on the virtual machine can change or damage your real computer, or its software.
Most of the use cases mentioned here are achievable with Containers today. The big difference UML provides in, is with a separate kernel. UML is an implementation of Linux as an architecture of Linux itself. It supports x86 and x86_64 architecture. And given that it is the port of the kernel, you can do many of the tests and experiments of the regular kernel, safely inside a confined UML environment. As with other virtualization implementations, the limitation comes in if you are working on physical hardware. With its re-entry in Debian, I wanted to revive my local setup. First is the packaging structure and the second is its integration with current standard tools
  • Packaging: For packaging UML in Debian, we rely on the packaged linux-source package provided by the kernel team.
    • linux-source package: We build UML from the linux sources that are provided by the debian kernel team. This works fine for now. Whenever there's a kernel vulnerability, there'll be an updated source package, to which we'll rebuild the UML package.
    • Merge with debian-kernel: In the longer run, we'd like to push UML package into the debian kernel team. UML is a component of the Linux kernel, and that is where it should be built from.
  • Integration: It works fairly well right now. On modern systems with systemd, where (nspawn) containers can easily have a network interface bound to it, UML lacks a bit behind. It'd be nice if we could see some UML integration with systemd.
    • Networking under systemd: Setting up networking, for UML, under systemd is fairly straight. In fact, with systemd, it is much simpler. Below is the host network (tuntap) setup, to which UML can bind for all its network needs.
rrs@learner:~/tidBits (master)$ cat /etc/systemd/network/tap.netdev

systemd allows for defining user/group ownership in its file. With this setup, and uml-utilities running, one can simply fire a UML instance as below:

Ritesh Raj Sarraf: Fully SSL for my website

I finally made full switch to SSL for my website. Thanks to this simple howto on Let's Encrypt. I had to use the upstream git repo though. The Debian packaged tool, letsencrypt.sh, did not have enough documentation/pointers in place. And finally, thanks to the Let's Encrypt project as a whole. PS: http is now redirected to https. I hope nothing really breaks externally.

Ritesh Raj Sarraf: Leprosy in India

During my recent travel, I had quite a long layover at the Doha International Airport in Qatar. While killing time, I watched an interesting programme on the Al Jazeera network. The program aired on Al Jazeera is Lifelines. This special episode I watched, covered about "Leprosy in India". After having watched the entire programme, I felt the urge to blog about it. First of all, it was quite depressing to me, to know through the programme, that the Govt. of India had officially marked "Leprosy" eradicated from India in 2005. As per Wikipedia, "Globally in 2012, the number of chronic cases of leprosy was 189,000, down from some 5.2 million in the 1980s. The number of new cases was 230,000. Most new cases occur in 16 countries, with India accounting for more than half." Of the data presented on Lifelines, they just covered a couple of districts from 2 States (of the 28+ States) of India. So, with many states remaining, and unserveyed, and uncounted, we are far away from making such statements. Given that the Govt., on paper, has marked Leprosy eradicated; so does WHO. Which means that there is no more funding to help people suffering from the disease. And with no Govt. (or International) funding, it is a rather disappointing situation. I come from a small town on the Indo-Nepal intl. border, named Raxaul. And here, I grew up seeing many people who suffered from Leprosy. As a child, I never much understood the disease, because as is mentioned in the programme, I was told it was a communicable disease. Those suffering, were (and are) tagged as Untouchables (Hindi: ). Of my small town, there was and still is a sub-town, named Sunderpur. This town houses patients suffering from Leprosy, from around multiple districts closeby. I've never been there, but have been told that it is run by an NGO, and helps patients fight the disease. Lifelines also reported that fresh surveys done by the Lepra society, just a 3 day campaign, resulted in 3808 new cases of people suffering from Leprosy. That is a big number, given accessibility to small towns only happens once a week on market day. And in 3 days the team hardly covered a couple of district towns. My plea to the Media Houses of India. Please spend some time to look beyond the phony stuff that you mostly present. There are real issues that could be brought to a wider audience. As for the government, it is just depressing to know how rogue some/most of your statements are.

Thorsten Alteholz: My Debian Activities in June 2016

FTP assistant This month I marked 233 packages for accept and rejected 29. I also sent 11 emails to maintainers asking questions. Currently there are 33 packages in NEW and the minimum this week has been as low as 24 packages. Come on you fellow developers, where are your packages? I am sure you can do better :-) . Debian LTS This was my twenty-fourth month that I did some work for the Debian LTS initiative, started by Raphael Hertzog at Freexian. This month my all in all workload has been 18.75h. This resulted in patches for 13 CVEs and the following uploads: I also looked at mxml and libstruts1.2-java and marked CVEs for these packages as no-dsa . I also reviewed a patch of Salvatore for an embargoed CVE of xerces-c. Last but not least I looked at the remaining two CVEs for asterisk, but was not really able to create working patches This month I called again for testing php5. Thanks a lot to Stefan and anybody else who sent in their reports! As there are already new CVEs for php5 available, I am afraid I need your support again in July This month I also had another term of frontdesk work and answered questions or looked for CVEs that are important for Wheezy LTS or could be ignored. Other stuff I made some progress with the Alljoyn framework. Up to now the following packages are available: Unfortunately as some of those modules still need to be released in current versions, there are some gaps. Anyway, the next uploads will include an XMPP connector, to basically bridge a local AllJoyn bus to a remote AllJoyn bus over XMPP. Further, with the lighting module, real lamps can be switched on and off and much more. Also the Home Appliances and Entertainment Service Framework seems to be interesting as well. In the Javascript world I uploaded some new packages and uploaded new versions for the following packages:

  • Issued DLA 512-1 for mantis fixing an XSS vulnerability.
  • Issued DLA 513-1 for nspr correcting a buffer overflow in a sprintf utility.
  • Issued DLA 515-1 for libav patching a memory corruption issue.
  • Issued DLA 524-1 for squidguard fixing a reflected cross-site scripting vulnerability.
  • Issued DLA 525-1 for gimp correcting a use-after-free vulnerability in the channel and layer properties parsing process.
Uploads
  • redis (2:3.2.1-1) New upstream bugfix release, plus subsequent upload to the backports repository.

Michal Čihař: Weblate 2.5

After almost six months of development Weblate 2.5 has been released. It brings lot of improvements and it's quite hard to point few ones. The most important ones include support for Python 3, reports generators, placeables highlighting, extended keyboard shortcuts, configurable dashboard or group based ACLs. Full list of changes for 2.5: If you are upgrading from older version, please follow our upgrading instructions. You can find more information about Weblate on https://weblate.org, the code is hosted on Github. If you are curious how it looks, you can try it out on demo server. You can login there with demo account using demo password or register your own user. Weblate is also being used https://hosted.weblate.org/ as official translating service for phpMyAdmin, OsmAnd, Aptoide, FreedomBox, Weblate itself and many other projects. Should you be looking for hosting of translations for your project, I'm happy to host them for you or help with setting it up on your infrastructure. Further development of Weblate would not be possible without people providing donations, thanks to everybody who have helped so far! The roadmap for next release is just being prepared, you can influence this by expressing support for individual issues either by comments or by providing bounty for them.

Ritesh Raj Sarraf: Laptop Mode Tools 1.69 Released

Today is an auspicious day. For those who know (or follow) the Hindu religion will be familiar; Today is Maha Shivaratri On this day, It is great delight for me to be able to release Laptop Mode Tools, version 1.69 This release adds on many bug fixes and some enhancements. There is a new module (disabled by default) for cpuhotplug. The release tarball also includes a basic PolicyKit file for convenience, that packagers can use for the Laptop Mode Tools Graphical Configuration Interface. Apart from the policykit file, the graphical invocation script has been slightly fine tuned to work under pkexec and sudo. Some defaults have been tuned based on user requests - This should improve in situations where your External USB Mouse/Keyboard used to suspend after idle time periods. In January this year, I had the pleasure of meeting Bart Samwel in person at his office in Amsterdam. For those who don't know, Bart started off Laptop Mode Tools around 2004, and I took over maintenance around 2008. Meeting in person has been a delight, especially with the ones you work over email for years; This is something I cherished last year at Debconf 15 too. IMPORTANT:- Until now, Laptop Mode Tools project was hosted on Bart's webserver. Now, as you read, the homepage and mailing lists have changed. I'd urge all users to subscribe to the new mailing list and update their bookmarks. Homepage: https://github.com/rickysarraf/laptop-mode-tools/wiki Mailing List: https://groups.google.com/d/forum/laptop-mode-tools Note: For users who are not comfortable with creating a google a/c for mailing list subscription, you should still be able to subscribe with your personal email address. Please follow the steps in the mentioned homepage. Since last couple releases, I've also been providing RPM packages for Opensuse Tumbleweed and Fedora. The same should be available on the github release page. The Debian package will follow shortly in the Debian repository. Thank you and a Happy Maha Shivaratri. Har Har Mahadev.

Ritesh Raj Sarraf: Linux Power Savings 2016

Having moved to a new place, now at times, I also have to deal with power outages. As heat increases, the power outages will be much longer and more frequent. So much, that UPS and Power Inverters run out. Such are ideal times to measure idle power consumption for my laptop. Here's what my default (and idle) OS looks like. It should be standard to most "typical" users. Some minor odds could be apport, dnsmasq, and maybe, tor. Also, thanks to systemd, there are some native services which are now converted to socket activation based ones. There's also Laptop Mode Tools for userspace power savings. But huge thanks to Intel's work in making the kernel more power efficient. With things like Runtime PM and Intel P-State, we can now define, default and aggressive power-savings modes, helping conserve more power. We still have challenges with things like binary-only drivers; and also stock GPL drivers but with an external firmware blob. There have been many instances when my previous machines (which had both) ran into severe power drain. The challenge with power savings is that it is not just the job of the kernel. All components, kernel and userspace, need to be made aware of, and work in unison. Otherwise, one ill behaving web browser tab can be the cause of power drain. P-State driver seems to already be doing some scale down of CPU resources. And with CGroups maturing moe I think we'll eventually have all Desktop Environments making use of it.

So I used the standard power measurement tool, powertop. Below is a screenshot of PowerTop claiming 9 - 10 hours of possible battery backup. This is idle state. "Idle" would mean when the user is not interacting with the machine. When under basic usage (email, web), the actual battery backup I've sensed is somewhere around 6-7 hrs, which is still good from what we got a couple years ago. There's one oddity in the screenshot though. The estimated power consumption reported is 4.55W, where as, the power consumption of just the wifi card is reported 6.17W. That too, when the wifi was disconnected. This reminded me of the bug report against PowerTop, which is now more than 2 years old. We've still not concluded in that bug report, so if anyone can shed some light on PowerTop's reporting, please do share it in the bug report. Note: Please ignore the terminal's title in the screenshot. That is wrong and I've not bothered to figure out why it is displaying the title name constructed from an outdated session, which is already terminated.

Ritesh Raj Sarraf: Linux IO + Memory + CPU Contention

I very recently met someone, and we had a good productive discussion on the features and (long standing) bugs of the Linux kernel. No doubt, Linux is the most featureful kernel in the market. Is also a lot appealing given its breadth of platform support. Of that discussion we had, it led about Linux's behavior in tighter stressed scenarios where there is a lot of contention among the core subsystems. From the conversation, I got the feedback that perhaps the issue is no more valid. My conclusion was I must have missed out on the fix because I haven't really spent any Engineering Lab time in recent past. But a picture says a thousand words. And no, the issue is NOT fixed. And it is still simple to reproduce the bug. And it is just that we have faster advancements in underlying hardware, that we may eventually find it much harder to reproduce these bugs. The kernel spitting the screen is Linux 4.4 Stock Debian.

Ritesh Raj Sarraf: Unbricking my Linksys

In trying to improve the WiFi service in my house, I recently dug out my old Linksys WRT54G Router. It is a 802.11 bg router, which can do 54 MBPS. Currently, I use a TPLink based router, with a DD-WRT community firmware, which claims is 802.11 bgn and can do 300 MBPS. The overall wifi signal isn't adequate, so I thought of using the old router as a repeater. The default Linksys VXWorks firmware does not have the bridging capabilities, so it was time to flashback, again, the dd-wrt image onto it (The last time I did, I eventually had to revert back to the stock firmware because my ISP claimed that the router was giving too many packet drops). Being an old device, and me being lazy, I did not pay much attention to the exact steps; and ended up bricking my router, wherein it wouldn't give me the Management Console to flash a new firmware; nor would it give me the old VXWorks firmware interface. All it gave was a White Screen of Death and an active IP connection. Turns out I'm not the only one bricking routers, so some good soul documented the process on unbricking the router. I was in a slightly more better position than the author, cause I did have the network available. My initial hope was to just push the firmware image over tftp, and that it would work. But that didn't happen. So, I was forced to follow the steps in the article, i.e. to use the Windows Tool mentioned in it (Infact that is what triggered me to write the article). Not having Windows available, my choice was to try it out over Crossover/Wine. It got the job done; so Thank You. BTW, does anyone know what goodie does the Windows Tool do that plain tftp did not ? The Windows Tool too pushed the image over tftp, so it must be doing something within the tftp spec to trigger the firmware upload and flash. That done, getting the Repeater Bridge wasn't that painful. If you build a Repeater Bridge setup, just follow dd-wrt instructions. The only extra I'd add is that You should keep your Virtual AP's credentials the same as that of your Primary Router's AP's. I'm not sure why that is needed but that ate my good 2-3 hrs.

Ritesh Raj Sarraf: Lenovo Yoga 2 13 running Debian with GNOME Converged Interface

I've wanted to blog about this for a while. So, though I'm terrible at creating video reviews, I'm still going to do it, rather than procrastinate every day. In this video, the emphasis is on using Free Software (GNOME in particular) tools, with which soon you should be able serve the needs for Desktop/Laptop, and as well as a Tablet. The video also touches a bit on Touchpad Gestures.

Ritesh Raj Sarraf: State of Email Clients on Linux Based Platforms

I've been trying to catch up on my reading list (Thanks to rss2email, now I can hold the list longer, than just marking all as read). And one item from last year's end worth spending time was Thunderbird. Thunderbird has been the email client of choice for many users. The main reason for it being popular has been, in my opinion, it being cross platform. Because that allows users an easy migration path across platforms. It also bring persistence, in terms of features and workflows, to the end users. Perhaps that must have been an important reason for many distributions (Ubuntu) and service providers to promote it as the default email client. A Windows/Mac user migrating to Ubuntu will have a lot better experience if they see familiar tools, and their data and workflows being intact. Mozilla must have executed its plan pretty well, to have been able to get it rolling so far. Because other attempts elsewhere (KDE4 Windows) weren't so easy. Part of the reason maybe that any time a new disruptive update is rolled on (KDE4, GNOME3), a lot many frustrated users are born. It is not that people don't want change. Its just that no one likes to see things break. But unfortunately, in Free Software / Open Source world, that is taken lightly. That's one reason why it takes Mozilla so so so long to implement Maildir in TB, when others (Evolution) have had it for so long. So, recently, Mozilla announced its plans to drop Thunderbird development. It is not something new. Anyone using TB knows how long it has been in Maintenance/ESR mode. What was interesting on LWN was the comments. People talked a lot about DE Native Email clients - Kmail, Sylpheed. TUI Clients and these days Browser based clients. Surprisingly, not much was talked about Evolution. My recent move to GNOME has made me look into letting go of old tools/workflows, and try to embrace newer ones. Of them has been GNOME itself. Changing workflows for email was difficult and frustrating. But knowing that TB doesn't have a bright future, it was important to look for alternatives. Just having waited for Maildir and GTK3 port of TB for so long, was enough. On GNOME, Evolution, may give an initial impression of being in Maintenance mode. Especially given that most GNOME apps are now moving to the new UI, which is more touch friendly. And also, because there were other efforts to have another email client on GNOME, I think it is Yorba. But even in its current form, Evolution is a pretty impressive email client Personal Information Management tool. It already is ported to GTK3. Which implies it is capable of responding to Touch events. It sure could have a revised Touch UI, like what is happening with other GNOME Apps. But I'm happy that it has been defered for now. Revising Evolution won't be an easy task, and knowing that GNOME too is understaffed, breaking a perfectly working tool won't be a good idea. My intent with this blog post is to give credit to my favorite GNOME application, i.e. Evolution. So next time you are looking for an email client alternative, give Evolution a try. Today, it already does:
  • Touch UI
  • Maildir
  • Microsoft Exchange
  • GTK3
  • Addressbook, Notes, Tasks, Calendar - Most Standards Based and Google Services compatible
  • RSS Feed Manager
  • And many more that I may not have been using
The only missing piece is being cross-platform. But given the trend, and available resources, I think that path is not worthy of trying. Keep It Simple. Support one platform and support it well.

Ritesh Raj Sarraf: Device Mapper Multipath status in Debian

For Debian Jessie, the multipath support relied on sysvinit scripts. So, if you were using systemd, the level of testing would have been minimal. At DebConf15, I got to meet many people whom I'd worked with, over emails, over the years. With every person, my ask was to use the SAN Storage stack in a test environement, and report bugs early. Not after the next release. This applies also to the usual downstream distribution projects. That said, today, I spent time building a Root File System on SAN setup using the following stack, of the versions that'd be part of the next stable release:
  • Linux
  • Open-iSCSI Initiator
  • Device Mapper Multipath
  • LIO Target
I'm pretty happy that nothing much has changed in terms of setup, from what has already been documented in README.Debian files. The systemd integration has been very transparent. But that is my first hand experience. I'm request all users of the above mentioned stack to build the setup and report issues, if any. Please do not wait for the last minute of the release/freeze.

Ritesh Raj Sarraf: Touchpad Gestures

If you have a modern laptop, you must be having a touchpad with multitouch capability, in hardware. But on the software front, it must be crap. And if you've always craved for having support for those multitouch gestures, you must have been following the X/Wayland development. From what I've known so far, libinput is the successor to all older input support in X/Wayland. But it does have some conditions at this time. Like: Multitouch Gesture is only available in Wayland, not in X. Similarly, if you use GNOME/Wayland, not all RandR functionalities are available in Wayland, that are there in X. So if you'll still be using X for some time, and want Touchpad Gestures, you may consider looking at: https://github.com/bulletmark/libinput-gestures For Debian, this still needs to fixed before you can use. But if you read till here, you know your way.
