to other PH islands. Thankfully, when I go to places where I can
expect to get shot at, I always manage to get out unscathed.

For the price, performance and battery life, I carefully chose the
Dell Latitude E6540. My first choice was the Latitude E6430 ATG, or
the Latitude 14 Rugged Extreme, but in my middle-aged years the screen
size is very important for my eyes. The E6540 is also more readily
available. To safeguard against the storms, I ttravel around with my
laptop in a Pelican 1495 case.

Everything just works in my E6540 on Ubuntu LTS. Can't ask for anything more.

Linux Laptops


My 3 year old Thinkpad X220 broke down last week.  I was using Arch Linux on the X220.  It worked well the past 3 years but I am frustrated that it did not last long as I expected.  I am considering on buying a new one.  I am interested to know what you guys use and how satisfied are you running Linux on it.

Anybody using Chromebooks for sysad/development in the Philippines?  Is it viable?

Thanks in advance for the replies.

Cross-stack LACP

Hello pluggers!

For the past year (give or take a couple of months), I've been using moosefs as an inexpensive SAN/NAS solution.  It provides some level of HA on the storage side.  Now I'm looking at complementing it with some measure of HA on the network side of the infrastructure.

I'm looking for info on what switches (brand + model) are in use out there that do cross-stack link aggregation/bonding.  I'd like to hear from those who are actually using such a setup.  We've been asking various resellers for a POC, but all of them say they can't because the neither they nor their distributor carry demo units.

Squeezing the most out of KVM I/O performance

I have a server with Ubuntu 12.04 as host OS with a single RHEL4 KVM guest running.  At this point, I cannot upgrade that RHEL4 OS to any later version.  Since there is no virtio support in the guest's kernel, I'm stuck with IDE emulation.  And it is so sssslllloooowwww.

The guest machine is running MaxDB/SAPDB and executing CHECK DATA command which checks the entire database for data corruption.  The db's size is somewhere between 200GB and 250GB.  While it is running the data check in tty0, it is also running vmstat in tty1 and vmstat is showing a 1-minute (i.e. "vmstat 60") average of 75% iowait.

Simultaneously, I'm running vmstat also in the host OS, and it is only showing a 8%-10% iowait average.

Are there any particular tweaks I can do to improve upon the guest's iowait?  Bring it as close as possible to the host's.  I already have io=native set.

Revisiting PLUG

Today, I thought of saying Hi to this good old mailing list while I was cleaning my inbox, and also because I recognized some members of this list on security reports that reached my "other" inbox the other day.

So I looked into the threads as far as 2013 and I noticed that the topics are generally the same, just less bashing and fanboy-ism. Maybe it's just a sign that we're getting old or the majority simply moved on to OSX or just too busy working on their start-up ideas or their droid duties :-)

Ano na nga ba ang latest sa PLUG aside from having a G+ hangout that is organized using FB Events? ;-) Do you guys still organize tech meet-ups or conference? (in some areas, LUGs are still going strong e.g. I might be able to sponsor some projects too as long as it is something that interests me.

local municipal telco or internet provider

Hello all,
  nadaaanan ko lng while searching for applicable laws via google regarding putting up an isp or local telco in a remote place na wlang service
i  wanted to provide local & internet access to a place (south of mindanao) me mga time kasi na 1 to 2 weeks wlang signal ang cellphone, pag meron naman putol2x ang calls at d nasisend ang text.2 lng ang cell tower at halos d na accessible.
anyway my question is. ano po kaya applicable law na swak para sa plan ko? na d ako uulanin ng demanda etc ng mga mlalaking carrier. if meron man.
pagpasensyahan na po, wla lng ako idea on how to start.

Microsoft, IBM, Google and Other Tech Giants Team Up to Prevent the Next ‘Heartbleed’

Makakatulond din ito para sa hanap buhay ng mga programmers ng Open Source.

Nakikinabang na talaga ang mga companies na closed source sa mismong open source.

Microsoft, IBM, Google and Other Tech Giants Team Up to Prevent the Next ‘Heartbleed’


Technology giants including Google and International Business Machines have committed to collectively give more than $3 million to support the free, widely used computer code that underpins the Internet.

As participants in the Core Infrastructure Initiative, the companies will each provide $100,000 a year for a minimum of three years. The money will back projects aimed at improving open source software, code that can be modified and used by individuals and companies for free. While the total may be loose change for the tech firms, it could be quite a sum for open source developers, many of whom do work in their free time for little or no pay.

The Linux Foundation, a nonprofit group that advocates for the growth of Linux and collaborative software development, announced the project Thursday. Along with the foundation, other founding participants include Microsoft Corp., Facebook Inc., Cisco Systems Inc., Dell Inc., Fujitsu Ltd., Intel Corp., NetApp Inc., VMWare Inc., Inc. and Rackspace Hosting Inc.

Recruiting for the initiative kicked into gear following the disclosure of the Heartbleed bug, a vulnerability in OpenSSL, an open source encryption tool used by a large portion of the Internet. The flaw could have affected two-thirds of active websites and potentially exposed troves of sensitive customer data.

Open source software is often seen as more secure than proprietary software. The more eyes on the code, the thinking goes, the more opportunity there is to improve on that code and spot potential issues.

“In this case, no one was looking at the code,” Jim Zemlin, executive director of the Linux Foundation, told CIO Journal. Heartbleed was the catalyst for launching the project, he said. “Can we together take a broader view and maybe lower the risk that the next Heartbleed will happen? I do think that is the case, with a modicum of resources.”

Open source software pervades the systems and software companies and consumers use every day, but many open source developers do so for little or no pay during their free time. “We have to provide resources in a way that allows them to operate the way they have been operating, in a way that allows them to do it full time without having to worry about their next meal,” Zemlin said.

The initiative will look across the spectrum of open source projects and determine which ones could be significantly aided by some funding. Support could include paying developers to work on new projects, funding security audits or improving computing infrastructure.

The first project being considered for funding will be OpenSSL, according to a statement from the Linux Foundation. Project proposals would be brought to a steering committee that would then vote on how to allocate money, Zemlin said. The WSJ reported earlier that at the time of Heartbleed’s discovery, OpenSSL was managed by just four European programmers, only one of whom counted it as his full-time job.

Shortly after the bug was disclosed, some firms floated the possibility of professionally testing open source software projects. “Testing of the core libraries has not been done in a highly orchestrated and organized manner, and I think it is time for that to be done,” said Trey Ford, global security strategist at Rapid7, an Internet security company. He noted that his firm does not provide the kind of source code review discussed at the time.

Mark Shuttleworth, founder of Linux operating system distributor Canoncial Ltd., voiced his “full support for this initiative.” He said Heartbleed “opened the world’s eyes to the extent to which open source is vital to vast tracts of infrastructure and makes it real to a much broader cross section of business and society.”

Still, he said the initiative should only be a first step in developing institutions capable of policing open source software. Ultimately, he said, other institutions will have to be created in order to ensure that not only software developers, but also security researchers and others involved in cybersecurity, have access to these kinds of resources. “The deep challenge is to figure out how to create a combination of openness and governance and sustainability for these widely used pieces of open source software that doesn’t just address the crisis of the day, but ultimately gives us more confidence in our ability to both avoid and respond to potential crises in the future,” he told CIO Journal.

Zemlin, who said future backers could include governments and members of the financial services industry, among others, hopes the initiative will serve as an outlet for anyone with a stake in open source to propose a project.

Calling open source “core to our strategy and development,” New England BiolabsInc.  CIO Ken Grady said many of the company’s scientific apps, such as those used for gene assembly and other experimental design tools, are open source. He said the firm’s heavy reliance on open source makes it “critical that we monitor and patch frequently to address threats,” including for serious flaws such as Heartbleed.

TradeMonster Group Inc., an online trading platform in Chicago, uses open source software as much as possible both in its trading system and internally, chief technology officer Sanjib Sahoo said. The company goes through a lot of work to test open source software before running it in its network.

Many companies that want to save money with open source software don’t do enough testing, he said. “They don’t go through a lot of security, performance and compatibility testing.” TradeMonster was not impacted by the Heartbleed flaw in OpenSSL as it didn’t use the version of the software that was vulnerable, Sahoo said.

copying multiple DVDs

I'd like to build a Linux machine that will simultaneously burn several 
(say, 10) DVDs from an original ISO file. It is our DVD, so no copyright 
issue is involved here.

I find burning from a single burner too slow, if I want to burn, say, 
100 copies quickly.

What I have in mind is to connect 10 burners to one machine. Then, to 
have 10 instances of K3B (or some similar disk-burning software, K3B is 
best though...) running, each instance using 1 of the 10 burners.

Is this at all possible? The PCs I've seen have at most 4 SATA ports, 
and one of these is for the hard drive. That leaves only 3 for 3 burners.

If I connect a DVD burner to SATA ports 2, 3, and 4 (#1 is used by the 
hard disk), will this idea work?

How do I connect more than 4 SATA drives to a PC?

Thanks in advance,

Obet Verzola

PS. To the curious: I work with farmers and we have a training video for 
farmers that we produce on demand, and sometimes we need to do so quickly.
