Netrunner Rolling 2014.04 - This time, we need the goats

updated November 24, 2014, category: Software & security

Netrunner Rolling 2014.09
Netrunner Rolling distro release is a very interesting concepts, on many level. It's a KDE desktop, based on Arch and Manjaro, the latter also being partially based on Arch itself, plus it comes with a rolling update model. A far cry from the typical asterisk-buntu philosophy that pervades most of the market.

In the canonical notation, Netrunner Rolling is actually an Arch-Arch-Manjaro distro, and this actually sounds like Ice Ice Baby, only geekier. Arch, Arch, Manjaro. Tam dam dam da da dam dam. Sort of. Anyhow, we have a new edition out there. 2014.09. So let's see if it's any good. The previous one surprised, immensely. Follow me.

Stupid stuff what I encountered

Stupid & funny
After reading my Funny stuff what I encountered article, you must probably be craving NOT for more stuff of the same high caliber. Indeed, it is time for something resembling a sequel. Less software more interesting things from all aspects of life, hence this section.

Let us then take a look at some of the randomly silly and yet curiously humorous and ever so gently cretinous ideas and concepts that came about in the past few years. Not quite the stellar candidates for my Greatest sites section, but good enough to merit a handful of paragraphs here. To wit.

OpenSUSE 13.2 review - Back in the game!

updated November 21, 2014, category: Software & security

openSUSE 13.2
For me, openSUSE has always been a special distro. THE first distro. I've kept on using loyally it for many years, even as Ubuntu started making huge progress and stealing major portions of the Linux market share. But then, with the release of the 12th edition, something big changed. The magic evaporated.

Since, my heart has not really been captivated by SUSE. Not like it used to be. It works fine, but never perfectly, never up to its full potential. Similarly, the last version, with so much beauty and style, it could have been the lead distro of the year, and yet it failed to do that. So maybe openSUSE 13.2 will spark the green chameleon renaissance. Let's see.

Scientific Linux 7 - Poorly executed

updated November 19, 2014, category: Software & security

Scientific Linux 7
Apart from CentOS, another distro I have really been waiting to explore is Scientific Linux. With its solid RedHat base plus extra software, it could be an excellent contender for the ultimate desktop distro. And so our quest continues.

What will amaze you even more is my decision to try the Gnome edition. Yup, after some three years of ignoring Gnome due to its stupidity, I decided to give it another try, just for fun, to see what gives. Maybe it can redeem itself, or be redeemed by Scientific Linux. Either way, it's an interesting test.

Opel Astra triple review!

updated November 17, 2014, category: Car reviews

Opel Astra triple review
One of the perks of working in a hi-tech company is that most people around you have predictable patterns. We won't really call them borgs, zombies, code monkeys, or anything untoward like that. Simply homogenous in every sense, including their taste in cars. Thus, when you have three chums, one who drives an Astra five-door hatch, another who drives an Astra Sports Tourer station, and the third bloke who transports himself in an Astra Berlina sedan, you have a triple review. W00t!

Anyhow, three generous people let me monkey about around their Astras, for the sake of this review. Plus, I ended up driving one for a whole week, which adds to what I can write in this little article. Anyhow, all of the tested vehicles had the standard trim level, a 1.4-liter turbo-charged engine, and a six-speed auto gearbox. Concordingly, this review. Ergo.

Microsoft EMET 5 review - Familiar goodness

updated November 15, 2014, category: Software & security

Microsoft EMET 5.0
If you've come around here before, you will have noticed a bunch of interesting things: Fascination with goats and minefields, humor de la extreme and yes, talk about EMET, which happens to stand for Enhanced Mitigation Experience Toolkit, a software created by Microsoft and designed to stop all kinds of exploits from pwning your boxen. In reality, it's more than that. It's a good coding ninja. Fail your OOP and the program goes down.

I really love the concept. Add your program into the EMET list, and from that moment on, it is monitored for violations in the memory space. It might be totally legit, but if it decides to misbehave, it will be stopped. That's what EMET does, and that's what makes it totally superior to all those would-be anti-malware nonsense programs. And now, we are going to take a look at the latest version five dot oh or one, whichever you prefer, and see what's new on the block. Follow me.

Kubuntu 14.10 Utopic Unicorn with Plasma guns!

updated November 14, 2014, category: Software & security

Kubuntu 14.10 + Plasma 5 review
Ubuntu family experience, take three. We had two reviews so far - like duh! - the first being all about Ubuntu. It was a massive failure, because screenshots did not work and the installer would not format partitions. Then, I tested Kubuntu 14.10, and it worked rather well, albeit with some restraint and boredom ingrained in its DNA.

Now, we will try to make the Kubuntu experience more magnificent. We will be riding majestic fiery steeds, flying through coruscating clouds and rainbows, firing Plasma cannon at the unsuspecting Linux crowds. In other words, we will attempt our luck at the technical preview of Plasma 5, which aims to replace the classic KDE4 framework. Let's go.

Foldit - In the name of science, solve thy puzzles!

updated November 12, 2014, category: Software & security

Protein folding is one of the big challenges in modern science. In a nutshell, the fine arrangement of molecules into protein shapes determines their functionality. It may work, work badly, or not at all, and it comes down to angstrom-alignment between different bits and pieces, caused by the forces of physics. If you know the exact folding pattern, then you can essentially control the protein as you see fit.

Sounds easier than it is. Indeed, millions of computers worldwide are busy trying to fold proteins 24/7, testing a virtually endless number of folding options. It's done scientifically, without direct human input. However, a bunch of scientists is testing a possibility of using humans as a far more efficient alternative. In other words, we could use our spatial awareness to figure out geometric alignments in seconds, which could take a typical computer years to solve. Which is where Foldit comes in.

Opel Adam review - A feisty little car

updated November 10, 2014, category: Car reviews

Opel Adam
The story behind how I got to test Opel Adam is quite interesting, and maybe even sad. Having found myself owning an Opel Corsa OPC after an amazing initial experience during the test drive, the car ended up in the service shop less than 24 hours after the delivery, due to a faulty A/C unit. Which meant the Opel folk were quite embarrassed and they handed me over their Adam demo unit without argument, while my hot hatch was being mended and taken apart, losing its pristine virginity.

But the upside of this story is that I had an Adam in my hands, with nary 1,800 km on its clock, and a whole week to play with it, driving around, cruisin', doing all the pimpy stuff that posh neo-urbanite pimps like me do, especially when they find themselves seated in a posh little car like Opel Adam. We review.

Kubuntu 14.10 Utopic Unicorn - That's better

Kubuntu 14.10 Utopic Unicorn review
You must remember my Ubuntu 14.10 review from just a few days back. You must. It was a monumental, unexpected failure that soured my weekend and made me feel like a fool. Which is why I hurried with the Kubuntu testing, to try to restore my sanity.

In fact, we will be having two reviews. A standard one, featuring the KDE4 desktop framework, and then one with the brand new Plasma 5 tech preview, which should be a total blast, given my previous experience. Our test box is an old T61 machine, with aging Intel graphics, but decent performance due to a couple of cores, 2GB RAM and two SSD. It did not cooperate well with Ubuntu, after a hundred splendid distro reviews in the past years, so let's see how it fared with Kubuntu.

Linux on the down low - Your responses

Linux on the down low - responses
Several weeks back, I wrote a possibly worrying article about the lack of enthusiasm and activity in the Linux community in the past few months, reflected in reduced chatter and passion in the forums, fewer news, Linux-oriented sites closing down, and a general attitude of meh. The responses were many and varied.

I was surprised by the number of people who mailed in their opinion, showing that not all is lost, and that there is still hope. More importantly, the range of ideas and theories you offered is quite astonishing. It's always interesting to learn how people think, and delightful to be amazed by someone's thoughts.

Ubuntu 14.10 Utopic Unicorn review - No rainbows

Ubuntu 14.10 Utopic Unicorn review
Autumn season, rain and distros, both hailing down on us, like the proverbial, eh, rain. Yes, twice a year, developers pump out fresh releases from their digital forges, and our never ending hunt for the perfect distro begins anew. With Trusty having set the bar so high, the challenge is ever more so exhilarating.

As always, I will begin with Ubuntu, then slowly branch onto the multi-lettered siblings of the family, and then test other distributions. The latest Canonical release is named Utopic Unicorn, and it's a somewhat silly name. But then, what does it matter. Follow me.

Indeed, today, I will expand on my recent exploration of CentOS and show you how to install this operating system in a side-by-side configuration with Windows. The nice part is, the basic concept remains true for all versions of Windows, so if you're running later editions, then this tutorial is also good for you. Follow me.

Hyundai Elantra review

Hyundai Elantra 1.8
We are back in the United States, for another review of a car with automatic transmission. This time, it's Hyundai Elantra, driven and tested for a period of about a week across California and Nevada. It's a medium-sized family car, designed to lug honest tax payers and their children about. Well, in the USA, it's labeled a compact car, but size isn't everything, right.

I will try to spill as much experience as possible onto the proverbial paper, but with just a handful of days of driving about, you won't get any long-term impressions, any big faults or issues. Still, it's a worthy experiment, and with a recent Jetta review, you will get a nice comparison into how each drives and what it offers to the prospective buyer. Follow me.

From Windows to Linux, Part 5: Mail clients

Windows to Linux - Mail
October 31 is supposedly supposed to be a frightening date, especially when it falls on Friday. Go figure. But no need for that. In fact, it's a happy date, because we are going to continue our Windows to Linux migration saga with a brand new chapter, and this one discusses the delicate topic of mail clients. I have never given a proper overview of this subject before, like ever, so this is a fantastic debut.

More specifically, we will discuss a handful of mail client software offerings available on a typical Linux distribution, talk briefly about how to set them up, and finally learn about the little tweaks and tricks needed to get everything working smoothly. We shall use Linux Mint as the test bed. Now, I did promise we would be trying different distros for different parts of our migration journey, but just to be random and unpredictable, I went for Mint once again. No beef. Follow me.

Not everything is green. There are so many beautiful colors in the visible spectrum, and yet, nowadays, the only color that counts seems to be green. Everything and anything we do gets a green hype.

How to download Youtube video thumbnails

Youtube thumbnails
I hate it when people use a suggestive thumbnail for their videos, only to discover that the mediocre content has nothing to do with the little image, or with the title, or anything. Don't you? Now, I do understand the world revolves around utilitarian smut, and videos that mislead in their promise thereof should be penalized. But that's not why we are here.

I want to teach you a somewhat convoluted but effective way of getting video thumbnails downloaded. In the past, you could pause the playback and download the image easily. Recently, it's become a little trickier. We will do this without PHP, API and other geeky tricks. Just you and your browser.

VirtualBox & Windows 8
Windows 8 might soon be going away, which is why the notion of using it as a guest operating system in a virtual machine is more appealing than ever before. Hence, this article. Hence, this situation you are facing. You are trying to boot one of the 64-bit Windows 8.X family operating systems as a guest in VirtualBox. This may be Windows 8 or higher. Either way, the initial boot fails within seconds, and the virtual machine must be closed. The Error Code you get is: 0x000000C4.

HERE offline navigation application for Android

HERE for Android
One of the many advantages that Nokia phones have over their competitors is the presence of free, offline navigation software, in the form of Ovi and HERE Maps, the latter installed and configured on the Lumia line of products. Indeed, this has always been one of the critical arguments I used against Android and the likes. No more.

Recently, HERE maps have also become available for Android. True, we're talking beta software, and at the moment, it's available from the Samsung store, which means you will need a Samsung device to test and play. In my case, an S4 bricklet. Later, this should become available for all Android platforms. But let's see what gives.

Marble is not just a rock, it's software, too

updated October 10, 2014, category: Software & security

Marble, the one we are referring to here, is a free, open-source world atlas and virtual globe software somewhat akin to Google Earth and friends. It is also a part of the KDE software suite, which makes it even more interesting. Now, it's no stranger, either, and we have seen this little tool in action a few years back.

I decided to re-explore [sic] Marble once again and see what it can offer, especially now that version 1.9 has been released. Sadly, the new build is only available for Windows at the moment. Ironic, is it not. The version present in most distro repos is still held back at 1.8, but that ought to be enough. I did run the new edition in Windows 7, for comparison's sake, and I could not see any huge changes, so we will have to do with a slightly older version. Follow me.

Windows 10 review - A good Start

Windows 10 Preview
Good day, ladies and gentlemen! Exactly approximately two and a half years after the ultra-controversial Windows 8 Consumer Preview was unleashed unto the Internet masses, we now have the latest and possibly greatest Microsoft operating system release available for early exploration. Released at the beginning of October, Windows 10 is a hallmark version for several reasons. One, Redmond guys have skipped a number, golly. Two, it might redeem the company from the two and a half years of failure inflicted by the previous release.

Since my techno barometer is absolutely accurate, which you can now totally relate to after reading my Consumer Preview and Enterprise RTM review, my verdict today shall signify the market success of Windows 10 in the coming years. So it is quite crucial that you read on and see what I have to say. Right now.

However, since I have recently upgraded parts of my extensive home network with a bunch of new appliances, including 1Gbps LAN and whatnot, I have three spare WRT54GL routers available for games. Never one to introduce unknown, untested changes into a production setup, I now have the luxury for custom firmware tweaks. So let's see if the famous DD-WRT can justify its reputation.

KIA Cee'd versus KIA Forte - A family duel!

KIA Cee'd vs Forte
Writing this dual, head-on review was not a simple thing. I had to find the right owners, with the right cars, and convince them, i.e. threaten them, to relinquish them for a few moments so that I could review them and tell about my experience. Luckily, I happened to stumble upon two hi-tech workers, both married men with offspring, poor sods, both with a dire necessity for a family car as familiar as they get. One happened to choose Cee'd Station as his baby troops carrier, while the other went for the more traditional Kia Forte saloon.

And so here we are, in a first Dedoimedo same-company rivalry match, to try to estimate which of the two offers better bang for buck for the archetypical middle-class guy, whose first priority is some comfort and a bunch of boot space, with performance and alike taking a distant second place.

First world problems
Welcome to Dedoimedo's pit of despair. Today, we will discuss everything in one article. All of the problems that plague us. All of them. Physics tells us there are eight laws of conservation, covering energy, momentum, weak isospin, and a few other geeky terms. However, what physics fails to account for is the ninth law. The law of human bitching.

For any given situation, humans will complain at a constant rate, regardless of what the problem is. Therefore, if you are not facing starvation problems, flooding, earthquakes, war, crime, and other human trifles, you will elevate other problems to the top of the list in order to preserve your perception of wrongness being done unto you. To wit, security vulnerabilities in software, phones that bend and nude celebrity leaks. Let's discuss.

In the last several years, we have had a whole bunch of system administration, troubleshooting and hacking articles here on Dedoimedo. Mostly related to Linux, and we learned how to fix system issues by combining the power of methodical investigation and analysis with nifty tools and utilities. Among the many, we used strace, lsof, oprofile, and others. Links below.

We even had a through so-called super-duper debugging guide, which combined the power of several programs all at once in order to resolve very complex performance related problems. However, we have mostly dwelled in the domain of userspace, less so in the kernel. In my OProfile article, someone even asked me for a practical example where a kernel profiler could actually yield useful results. Well, now the time as come, oh-oh, to demonstrate just that.

Unlike the previous three guides, in this one, I am going to show you not just how easy the transition is, and how successful you can be when you follow all the steps, I am also going to demonstrate failure. Not always is the migration simple or worth your time. And sometimes, despite your best efforts, you might fail. The important lesson is not to despair when this occurs, as we shall soon see.

Linux on the down low
Is it just me, or has the Linux arena recently gone rather quiet, unspectacular, boring? I am asking this question, because I have noticed that many of the sites I often visit for a glimpse of their latest news and posts have simply reduced their overall online visibility to the point of extinction.

Moreover, there's more and more focus on the mobile and such, which is kind of understandable, but I am seeing a loss of identity, a mutation of a once recognizable profile of many of the leading Linux sites into a template-like three or four-column news reel kind of thing, with the mandatory dynamic device viewing optimization, of course. Worst of all, the passion sees to be completely gone. So let's elaborate some more.

All right, let's do it. A few weeks back, I tested CentOS 7, and it did not really impress me. It had simply been rolled out too early, and there were no third-party packages available to make it more desktop-oriented and fun. Then, some time later, magic happened, Nux gave us the needed repositories, and CentOS became perfect once more.

In the desktop guide that explains how to beef up CentOS to be modern, beautiful and ultra-functional, I omitted a bunch of tips and tricks. On purpose. One of these is the installation of Nvidia graphics drivers on the selected machine, which turned out to be a handy but interesting exercise in the previous, CentOS 6 version.

Anyhow, I tested the new KDE release while still in an early stage several months back, and it showed great beauty and decent promise, despite being rather devoid of any real functionality. Since, dozens of releases have been baked, each one introducing fresh new incremental changes, making Plasma that much better and ready for the grand Mk.V release. Maybe. Let's see.

Several months back, I reviewed a relatively new Debian-based distribution named MakuluLinux, and while it did have lots of cool stuff, it was tailored with too much kitsch, some bugs, and a complicated installer. The developers read my review, responded with a nice friendly email, and took some of my commentary to heart.

Now, approximately half a year later, I am going to test Makulu again, this time the KDE flavor. And while the lack of a 64-bit version is still very much evident, perhaps there are other redeeming features that may delight us. The test box is my usual T61 laptop with its four distros spread on two SSD. Let's see.

Graphviz is the graph wiz

updated September 1, 2014, category: Software & security

Creating beautiful, compelling and all-telling graphs is not a simple thing. If you think you can just punch in a few numbers and expect charts to become a Kubrick kind of work all on their own, well they ain't. And to say nothing of more complex shapes and forms, or dependency graphs.

Graphviz is one of those tools that can help you bridge the artistic and talent gap present in your soul and fingers, maybe. Quoting the official page, Graphviz is open-source graph visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains. Jolly. Exactly what we need.

Gnuplot - Not for herding cows, great for graphs

updated August 30, 2014, category: Software & security

A great way to impress people is to show them a nice graph. Very few individuals are blessed with the ability to interpret numbers in a meaningful way, a-la Rain Man style. While they may see hidden patterns in a table of integers, most people struggle making those kind of connections, which is why they resort to images.

But there are images, and then, there are images. Nothing invokes disdain better than a default coloring scheme used in Excel generated graphs. On the other hand, the tight Matlab plots always cause a nice stir of professionalism, even when there's none to be found. So let me teach you about a program that will up your salary: gnuplot.

I drove Renault Clio Cup at the Grobnik racetrack!

updated August 29, 2014, category: Cars

Grobnik & Renault clio Cup
Driving a real sports car on a real race track is always a special kind of experience and a unique adventure. This year, I was lucky enough to find myself at Grobnik, a car-and-bike racetrack in northwestern Croatia. The car? A beautifully decalled Renault Clio Cup 2013, a one-make racing car with a 1.6-liter 210 HP turbo-charged engine and a six-speed sequential gearbox. Neat, if you consider the fact you get no driving assistance whatsoever, no power steering, no ABS, no ESP, no exhaust filtering, bare interior. However, you do get buckets, rollcage, a helmet with a built-in headset for communication, and yes, tons of unbridled 120dB engine noise.

Being an enthusiast and no stranger to cars with a significant scoop of muscle, I knew the track day would be different from a drive in a typical hot hatch, it's just that I underestimated how much different. Fun ensues, as you will soon discover. Anyhow, this article is not just a boring report, or a quick video clip. It's a whole story, and I suggest you stick and read all the little bits, and then watch the driving action. Let's roll. Cage. Joke. Hihi.

Top ten alternative software

updated August 27, 2014, category: Computer software

Top ten alternative software
Let's have a short break from the more tutorialesque side of articles on Windows to Linux migration. Only not quite. We will remain in the realm of this delicate subject, but rather than discussing specific topics, like mail, office and others, we will generalize. In other words, should a friend ask you, what software they can run in Linux, you will point them here.

The idea is not just to list software they can have when moving to a new operating system. It's about providing the exact same functionality that they used to have. Satisfying their needs so they will want to test Linux and then keep on using Linux. Now, we must be brutally honest and impartial, so there's a chance we might not have all the answers. All right, after me.

CentOS 7 - The perfect desktop guide

updated August 25, 2014, category: Software & security

CentOS 7 perfect desktop
My original review of CentOS 7 was less enthusiastic than I hoped for. That is because CentOS 7 did not quite deliver the punch that I expected. Truth to be told, this is the one operating system I am most excited about. Mint and Ubuntu are friendlier, but CentOS carries with it the solid confidence of old royalty.

Another glitch that came to bear in my review was that extra repositories with all that golden content you want were not ready. And so, I could not test most of the juicy stuff that we all need, like music, games and the rest. Now though, we can finally do that. This is the one guide that will transform CentOS into a truly remarkable desktop lean mean killing machine.

Windows 8.1 Wireless networking 101

updated August 23, 2014, category: Software & security

Windows 8 networking
Writing about an operating system that I seriously do not like is called philanthropy. I want to help stranded, clueless, unhappy people who are forced to live with Windows 8.1 on a daily basis, to make their experience that much less sucky. And one of the suckiest aspects of Windows 8.1 is networking, Wireless in particular.

User's ability to make changes have gone from geeky but intuitive to moderately stupid in Windows 7 to plain insane in Windows 8, as I will soon demonstrate. Once, you could just make your own rules and whatnot, but then Homegroups were invented and they introduced mandatory IPv6 connectivity, and now something even worse. Welcome to Dedoimedo's Wireless networking 101 crash course for Windows 8.1, which will hopefully make your pain go away.

Dedoimedo contest 2014

updated August 22, 2014, category: Software & security

Dedoimedo contest
Hello, folks! I am officially commencing to start a new Dedoimedo contest. To wit, if you choose to participate, at the end of it, you will be eligible for a lottery draw, in which you might win a handsome electronic device, a smartphone, a tablet or some kind of a laptop. The prize has yet to be decided, and at this point, you might be more interested in the little details behind this event.

Last year, we had the Ubuntu smartphone contest. Alas, Canonical did not manage to release a device with Ubuntu on it, however, true to my word, one of the contestants, an American lad named Christopher Ledbetter did win himself a Nexus 5 device, roughly worth 350 dollars. What did he do to get that? He read my books, wrote a bunch of reviews and got lucky.

The Forgotten is published!

updated August 22, 2014, category: Books

The Forgotten
Dear fellas, I am most pleased to announce The Forgotten, the third and penultimate volume in The Lost Words epic, and some would say grimdark, fantasy series has been released. The paperback version is available on Amazon, with the Kindle edition coming shortly.

Anyhow, The Forgotten continues the tale of the Realms and gods and whatnot. Some new characters are added, others are given focus, a whole lot of them get killed. Unlike The Broken, which jumps in time quite a bit after The Betrayed, this one picks up right after the last page of the second book. And it's a little shorter, by a whole 100 pages!

Mini review of Opel Corsa OPC - What a car!

updated August 22, 2014, category: Cars

Opel Corsa OPC
The free translation from Latin reads PC-BSD has a new desktop environment, it is called Lumina, and it is now being reviewed by Dedoimedo. Tricky language, Latin, right? Anyhow, we are here to taste a new, lightweight desktop, created by the PC-BSD team.

It's licensed under BSD, based on Qt and Fluxbox, the second default offering in the PC-BSD 10 Joule release, which we have tested some time back, and it is still alpha quality, so everything you see here today may or may not be true. We shall commence.
