Linux Kernel 3.8.x Gets Extended Support

2013-05-15T00:42:00.000+07:00

As +Greg Kroah-Hartman has EOL'ed Linux Kernel 3.8.x starting from 3.8.13, there are no LTS support for any modern Linux Kernel releases since Greg are maintaining two kernel version already and he didn't want to add the third one (not until he released one of them).

Slackware Linux is planning to use Linux Kernel 3.8.x for their default kernel stock in their next release (don't ask when. IT WILL BE RELEASED WHEN IT'S READY), but doubt has rising in since the kernel has been EOL'ed and that means no further support for this tree, which is no good for a distribution.

Ubuntu Kernel Team is stepping forward to take care of the Linux Kernel 3.8.x branch since they used the same kernel version for their 13.04 Ubuntu Linux until August 2014. More information about Ubuntu's approach can be seen on their wiki page.

Hopefully Pat is convinced with this good news and keep 3.8.x for the next Slackware release and not using the old 3.4.x (which has LTS support from Greg).

G7 Reunion

2013-05-12T05:57:00.001+07:00

It has been several months since our last reunion, but we finally managed to meet after Andre came back from US for the next two weeks in Indonesia and we had a long holiday this week. We were planning to stay in Kaliurang for two nights, but i can only join them partially since i have a baby to be taken care of.

Last night, we decided to join the party and we had a short BBQ party, but the party didn't last long since she was crying so loud and didn't stop for some time, so i guess she is not ready for that kind of party. We had to take her home and left the party earlier.

Sorry guys for not being able to join the party longer, but i do have higher priorities on the baby first.

New Editor and Image Upload Support in Blogger iOS App

2013-05-07T20:58:00.000+07:00

Blogger has just updated their iOS application to support new WYSIWYG editor and also support for image upload through the editor. This is something that i have been waiting for since up to yesterday, there are no way to upload images using the native apps in iOS. The only way is to use the web version.

Thanks to Google for updating the apps and implementing this feature in iOS :)

KDE 4.10.3 Released

2013-05-07T06:35:00.002+07:00

A monthly update for KDE 4.10.x branch has been released by KDE Team. They are polishing this branch by releasing KDE 4.10.3 on May 7 2013. The focus is bringing bug fixes and translation updates. It's safe to upgrade to this version if you have been using previous 4.10.2 or even if you used older version of KDE, namely KDE 4.9.

As with last month, the main area that KDE tried to improve is KWin and also PIM suite. See the KDE's Bug Tracker for complete list of bugs that has been fixed on this release.

WebPG for Firefox and Chrome

2013-05-05T22:41:00.000+07:00

I have been searching for a software replacement for fireGPG, a GnuPG tool management for Firefox to manage GnuPG operations/management. The project was discontinued three years ago because the author didn't have time to continue following GMail's changes.

Today, i found the alternative and that is WebPG. It's available for Firefox and Chrome. It's actively developed in github repository (Firefox and Chrome) by Kyle L. Huff. It still has some issues, but for most cases, it's not completely their fault and some of them are GMail's fault.

Let me know if you like this project :)

New NVidia Linux Driver

2013-05-02T22:14:00.000+07:00

NVidia has released a new version of Linux Driver: 319.17. This new version brings a lot of new features mentioned below:

Added support for the following GPU:

GeForce GTX 650 Ti BOOST
GeForce GT 720M
GeForce GT 735M
GeForce GT 740M
GeForce GT 745M
GeForce GT 750M

Fixed a regression that caused multiple BUG messages to be printed in the kernel log on SMP systems.
Fixed a bug that could cause the X server to crash when repeatedly enabling and disabling displays.
Updated nvidia-settings to preserve the relative positioning of displays when changing from a layout where multiple displays are on the same X screen to one where the same displays span multiple X screens.
Fixed nvidia-settings to dlopen(3) "libvdpau.so.1", rather than "libvdpau.so".
Added nvidia-persistenced, a daemon utility, to the driver package. nvidia-persistenced can be installed to run on system startup or manually run to allow the NVIDIA kernel module to keep persistent driver state allocated when no other user-space NVIDIA driver components are running.This can improve startup time for other user-space NVIDIA driver components.
Fixed CVE-2013-0131: NVIDIA UNIX GPU Driver ARGB Cursor Buffer Overflow in "NoScanout" Mode. This buffer overflow, which occurred when an X client installed a large ARGB cursor on an X server running in NoScanout mode, could cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution.

For more details, see: http://nvidia.custhelp.com/app/answers/detail/a_id/3290

Added initial support for restoration of efifb consoles on UEFI systems where the primary display is driven over VGA or TMDS (e.g. DVI, HDMI, or LVDS).
Added support for the xorg.conf Monitor section options "Ignore", "Enable", "Primary", and "Rotate".For example, to rotate a monitor identified by a specific EDID hash, one could add the following to /etc/X11/xorg.conf or a file in /etc/X11/xorg.conf.d:

Section "Monitor"
Identifier "DPY-EDID-ee6cecc0-fa46-0c33-94e0-274313f9e7eb"
Option "Rotate" "left"
EndSection

See the README and the xorg.conf(5) man page for more information.

Added an Underscan feature in the nvidia-settings X Server Display Configuration page which allows the configuration of an underscan border around the ViewPortOut.This feature was formerly known as Overscan Compensation.
Added support for application profiles to the NVIDIA client-side GLX implementation. See the "Application Profiles" chapter of the README for more information.
Added support to nvidia-installer for crytographically signing the NVIDIA kernel module. See the "Installing the NVIDIA Driver" chapter of the README for more information.
Added the "PanningTrackingArea" and "PanningBorder" MetaMode attributes.
Added support for RandR 1.3 panning.
Improved performance when the Accel option is disabled.
Added initial support for RandR 1.4 Provider objects with the Source Output capability, which can be used to render the desktop on an NVIDIA GPU and display it on an output connected to a provider with the Sink Output capability, such as an Intel integrated graphics device or a DisplayLink USB-to-VGA adapter.See the README for details.
Added nvidia-modprobe, a setuid root utility, to the driver package. nvidia-modprobe can be used by user-space NVIDIA driver components to make sure the NVIDIA kernel module is loaded and that the NVIDIA character device files are present.When possible, it is recommended to use Linux distribution native mechanisms for managing kernel module loading and device file creation. This utility is provided as a fallback to work out-of-the-box in a distribution-independent way.
Updated the nvidia-settings command line interface to accept display device names, as well as optional target qualifiers, e.g.

nvidia-settings -q [DVI-I-0]/RefreshRate
nvidia-settings -q [GPU-1.DVI_I-1]/RefreshRate

Updated the nvidia-settings command line interface to no longer assume the "X screen 0" target, when no target is specified in query and assign operations.Instead, all valid targets of the attribute are processed.
Fixed a memory leak that occurred when destroying a GLX window but not its associated X window.
Fixed a bug that could cause nvidia-installer to fail to delete directories created as part of a previous installation.
Updated nvidia-installer to report failures to remove installed files or restore backed up files with a single warning message, instead of a separate message for each individual failure.
Improved the performance of modesets in cases where the mode timings remained the same, but other parameters of the mode configuration, such as the ViewPort or panning domain, changed.
Fixed an issue with RENDER convolution filters.The driver will no longer normalize filter kernels before accelerating them.
Improved debuggability of the NVIDIA OpenGL libraries by including proper stack unwinding information on all supported architectures.
Updated the dkms.conf file and the makefile for the NVIDIA Linux kernel module to allow DKMS installations on systems with separate source and output directories.
Fixed a bug that caused RENDER Pictures to be sampled incorrectly when using nearest filtering in some cases.
Added support for the RandR "Border" and "BorderDimensions" Output properties, which can be used to configure the ViewPortOut of an RandR output.This is functionally equivalent to the "ViewPortOut" MetaMode token.
Fixed a bug where RRGetCrtcInfo could report incorrect size information when an RandR output has a custom ViewPortIn.
Further improve performance of some versions of HyperMesh with Quadro GPUs.
Added a VDPAU page to the nvidia-settings control panel, to display information about the decoding capabilities of VDPAU-capable GPUs.
Added support for dynamic mode management through RandR, e.g. via the --newmode, --rmmode, and --delmode options in xrandr(1).
Increased the number of pages that are shareable across multiple processes in the x86 build of libnvidia-glcore.so, by reducing its R_386_PC32 relocation count.
Fixed a bug that caused XVideo applications to receive BadAlloc errors after VT switches and mode switches that occurred while a composite manager was running.
Removed the X driver's support for "CursorShadow".
Updated nvidia-installer to attempt unprelinking files whose checksums do not match the checksums recorded at installation time.
Switched .run package compression from gzip to xz.This provides a higher level of compression.

Go grab it here (32 bit and 64 bit version)

Good Bye 2, Welcome 3

2013-04-28T07:40:00.001+07:00

Oh well, i'm 30 years old now and Google also knows about it too. I guess it's time to say good bye to 2[0-9] and welcome 3[0-9] :)

Viva Manchester United

IRIS II Completed

2013-04-22T22:44:00.003+07:00

Finally the second season of IRIS KDrama has been completed with another same ending, the main character died. This time, it's not by gunshot, but he died due to health problem and also because he took the nuclear bomb with a helicopter to an island far away from Seoul to minimize the casualties due to the effect of nuclear explosion which was estimated of bigger than the bomb exploded in Hiroshima Japan long long ago.

It's been a great movie, but then the ending that makes me kinda disappointed with the writer. I hope they produce IRIS III with a better plot in the end.

Patrick Volkerding's CafePress Account

2013-04-19T04:14:00.001+07:00

I saw an interesting thread on LQ about Patrick Volkerding's CafePress account. I recall few years ago, i tried to buy items from this site and yet it failed, because they weren't shipping to Indonesia and decline my transactions.

Since Ruario started this topic, i got curious if they have improved or not, so i tried to buy two items from them and it seems that they accepted my transactions this time. This is a great news since by doing this, i can directly help Slackware Project financially and it provides another alternatives to Slackware Store.

Let's wait for the next few weeks before the items reached my house. Can't wait to use them :)

Hacking Secret Ciphers With Python

2013-04-16T22:39:00.000+07:00

If you like Cryptography and you like to learn programming language, then i would suggest you to read Hacking Secret Ciphers with Python. It's available for free in PDF format or the online HTML version or you can buy it for $25 in Amazon.

What you will get is a fun tutorial with Python on Cryptography. This book is aimed at people who have no experience programming or with cryptography. The book goes through writing Python programs that not only implement several ciphers but also can hack these ciphers.

The book's website is available on http://inventwithpython.com/hacking

H@dfex Conference

2013-04-14T11:18:00.002+07:00

Last Saturday, i attended H@dfex conference in Royal Ambarrukmo after i got a free pass for the conference from the commitee. They even gave 5 discount voucher for students who would like to participate on this conference.

There i met several colleagues which was invited as a speaker and we had some discussions about security and also other things. Chances like this doesn't happened so often, so that's why i forced myself to attend this event even though i also have other activities on Saturday which is supervising the KKN program, but my schedule is for next week.

Thank you UII commitee for the free pass :)

Final LibreOffice 3.6.x Release

2013-04-12T01:45:00.000+07:00

The Document Foundation has released their last release for LibreOffice 3.6.x branch. They will focus on fixing bugs on LibreOffice 4.0.x and probably working for future release of LibreOffice 4.1.x.

This is an unplanned release as LibreOffice 3.6.5 was supposed to be the last maintenance release for 3.6.x branch, but then it was decided to have another release and this is it. It brings over 50 bug fixes since LibreOffice 3.6.5.

Users who prefer stability to more advanced features should stick with this release and for those who are willing to test new features should go with LibreOffice 4.0.2 which was released last week.

You can download it from their Download page, but you will have to switch the version to 3.6 since 4.0.x is the default option picked.

NVidia Start to Support Optimus Users in Linux

2013-04-10T06:08:00.000+07:00

NVidia has finally started to support Optimus in Linux Platform by releasing their new beta driver 319.12. By utilizing RandR 1.4, the new beta driver adds a way for drivers to work together so that one graphics device can display images rendered by another. This can be used on Optimus-based laptops to display a desktop rendered by an NVIDIA GPU on a screen connected to another graphics device, such as an Intel integrated graphics device or a USB-to-VGA adapter.

This is a great news for Optimus users as they don't have to use bumblebee project anymore and with further releases from NVidia, i think Optimus users should have smoother performance in the future.

Here's the changes in 319.12:
- Support for restoring of EFIFB consoles on UEFI systems with VGA/DVI/HDMI/LVDS/DP outputs.

- Support for the NVIDIA GeForce GTX 650 Ti BOOST graphics card.

- Support for application profiles to the NVIDIA client-side GLX implementation.

- Support within the NVIDIA Installer to cryptographically sign the NVIDIA kernel module as would be needed for SecureBoot.

- RandR 1.3 panning support.

- A new nvidia-modprobe user-space utility.

- Improved debugging of the NVIDIA OpenGL libraries by including proper stack unwinding information.

- RanDR Border and BorderDimensions output properties.

- Better HyperMesh performance for some versions on Quadro GPUs.

- A new NVIDIA VDPAU page is present on the NVIDIA Settings control panel to display decoding capabilities of GPUs.

- Memory leak, bug, and performance fixes.

KDE 4.10.2 on Slackware-Current

2013-04-08T00:40:00.001+07:00

Nowadays, Slackware-Current is quite active and it's taking most of the bleeding-edge applications such as XFCE 4.10.2 and KDE 4.10.2, GLIBC 2.17, GCC 4.8.0, and many others. This is a good sign that next Slackware release will be another great release as usual and it should support major components out there without any big issues.

Next release should also mark a new milestone where it should be a UEFI-compliant version of Slackware. Patrick is working hard on this issue with the help of others.

Meanwhile, Eric Hameleers is now working on an ARM port of Slackware on his new Google Chromebook. He is targeting the next Slackware release to bring a full ARM port of Slackware that can be used for modern CPUs

New NVidia Drivers for Linux

2013-04-04T01:45:00.002+07:00

NVidia has released three updates to their proprietary drivers for each category:
Latest Long Lived Branch version: 310.44
Latest Short Lived Branch version: 313.30
Latest Legacy GPU version (304.xx series): 304.88

All of them fixed one security update

CVE-2013-0131: NVIDIA UNIX GPU Driver ARGB Cursor Buffer Overflow in "NoScanout" Mode. This buffer overflow, which occurred when an X client installed a large ARGB cursor on an X server running in NoScanout mode, could cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution.

For more details, see: http://nvidia.custhelp.com/app/answers/detail/a_id/3290

Great news is that this driver also fixed a blank TTY problem found on 304.84. I have been waiting for this update as i can switch back to console or logged out from any DE back to my console instead of having a blank screen.

Thanks to NVidia for this update.

Firefox 20 Features

2013-04-02T12:52:00.001+07:00

For those expecting new Mozilla Firefox 20, here are the highlight of changes implemented in the final release:

Per-window Private Browsing
New download experience
Ability to close hanging plugins, without the browser hanging
Continued performance improvements around common browser task
Continued implementation of draft ECMAScript 6
New JavaScript Profiler Tool
blend modes supported by <canvas>
<audio> and <video> improvements
getUserMedia implemented for web access to the user's camera and microphone (with user permission)

You can download them in their FTP Server as of now, but expect an automatic update within 2x24 hours

MATE 1.6 is Close

2013-04-01T02:18:00.001+07:00

MATE 1.6 is getting closer as some of the core modules has been bumped to 1.6.0 release on their GIT repository. The roadmap indicates that most of their TODO list for 1.6 release has been completed and the rest is a minor task to do. We should expect a MATE 1.6.0 release on April.

I have been working closely with Chess Griffin to bring MATE Desktop 1.6.0 for Slackware users in our MSB project and we are preparing to test the upcoming 1.6.0 release when it's released.

I have personally prepared two virtual machines which i installed Slackware-Current and Slackware64-Current on it. Both are updated with the latest patch and update from Pat.

So far, the basic desktop has been quite stable, with some minor problem as noted in the KNOWN ISSUE file. I really hope that MATE Desktop will bring another great experience for those who liked GNOME 2.

GMail New Compose Menu

2013-03-29T23:02:00.002+07:00

As you probably have known, these days, GMail is pushing their new compose menu into public and you shall see them when you logged in into your GMail account and start composing new message or replying a message.

Unfortunately, it caused some problem (well, at least for me):
- It is by default set to HTML composer, where i would prefer plain-text
- Most of the options are hidden on the bottom part
- When replying a message, the original message is hidden and an additional click is needed to see them
- When replying, again, by default it will be top-posting. I prefer to have bottom-posting as many open source community prefer it that way

I am hoping that GMail keep their old composer as long as they can while they fix the above problems.

Play Games on the Web

2013-03-29T01:30:00.005+07:00

With the work of Mozilla and Epic Games, more and more developers are going to have a new platform for gaming environments: The Web.

Yes, Mozilla had released a new video showing how they ported Unreal Engine 3 playable on web browser. It's kinda fascinating since they ported this project consisting of lines of codes within 4 days with Emscripten and asm.js combined with WebGL.

Slackware Switch to MariaDB

2013-03-26T09:30:00.001+07:00

So, it's more than 2 days since my last post, but here's something interesting. Slackware and ArchLinux is now migrating to MariaDB and dumping MySQL in their repository. For Slackware, this change only happen in -Current tree, so the first official Slackware release with MariaDB will be on the next release, not in Slackware 14.0.

More and more Linux distributions are migrating to MariaDB after they feel that Oracle might do more changes to MySQL in the future that restrict Open Source developers and users to work closely with them. OpenSUSE and Fedora has done this and others might follow soon. Since MariaDB is backward-compatible with MySQL, replacing them should be easy to be done.

You can just remove MySQL and then install MariaDB without losing your data. Of course you are advised to backup your data first, but on my system, i don't really backup the data first and it's still safe.

Interviewing For YKFS V

2013-03-22T18:34:00.001+07:00

Tomorrow i will be interviewing students who would like to join the YKFS V. It's Yogyakarta Kampoeng Field School and this year, we had a collaboration with Hong Kong Polytechnic University. Last year, we had collaboration with PolyU and also ANU from Australia.

It's an honor for me to be selected as the coordinator for this year's YKFS program as i had just joined this program last year. Hopefully all goes well during preparations and also executions which will commence on this June-July.

Upgrading Server

2013-03-22T01:53:00.003+07:00

I'm planning of upgrading one of the server i maintain on my office. It's Slackware-based, so the upgrade process will be easy and straightforward since i have been using the same procedure over years and it's working on all of my machines that i used.

The only problem is the applications inside the server that needs to be checked with newer version, especially the web applications. Hopefully there won't be any major problem and i could have a safe and enjoyful upgrade.
