I'm really not a big fan of strategy-builder games (at least not since C&C), but Sid Meier's Civilization-series are more interesting than other similar games, at least in my opinion.
The game did have some peculiar bugs (ex: not running on selected screen in multi-monitor setups), but nothing major. The screenshots below were taken on an Intel Core 2 Duo Linux-laptop.

AMD FGLRX + Steam for Linux

DOOM 3: BFG Edition (non-steam version) - running natively on Linux. |
I have to note that laptops sporting AMD GPU's (integrated graphics-cards) don't work so well with the proprietary Catalyst-driver, I have tried to make it work on several occasions, but the driver (Catalyst) always seems to crap out. Unless you REALLY know what you are doing (manually tuning the Catalyst-driver), I would not recommend using Catalyst on laptops or notebooks.
ONLY use the Catalyst-driver if you are using a gaming-rig (desktop PC) with a discrete (separate component) graphics-card installed.

ACCELERATOR-TIP:
To enable video-accelerator (VA-)chips on discrete AMD-based (Radeon/HD) graphics-cards (on Linux), run the following command in a terminal on Ubuntu Desktop or Linux Mint:
sudo apt-get install xvba-va-driver libva-glx1 libva-egl1 vainfo
These libraries and drivers prevents video-artifacts/-tearing, stabilizes video-movement, de-processes video-interlacing and similar video-issues.I will be testing and experimenting with the open-source 3D/video driver for AMD-based cards at a later date, namely the Gallium3D-driver. And I'll be posting about it too, so stay tuned...

2 years Linux-gaming
SteamOS and Steam for Linux have really progressed the last two years. And with this year showing AAA-titles also wanting "teh' working Linux", things are really looking good for VALVe ;) :)
Personally, the bugs I've encountered playing beta- and alpha-games on Linux since December 2012 really weren't all that bad.
I really only had one major issue; the Steam-for-Linux client itself had some CPU-bugs.
In VALVe's defense, that was due to the fact I was launching it on a low-powered Asus Eee 900 netbook that sported an Intel Celeron 900MHz uni-processor (single-core). One lousy, 32-bit, barely-functioning little crappy "mini-computer".
This low-end CPU did not sport certain CPU-flags that Steam-for-Linux expected it to have, so they had to make workarounds for low-powered devices with integrated graphics (in part because of yours truly).
Apart from that VALVe-specific debugging, I've also sent a few bug reports to various game-studios about specific library-support issues, audio-bugs, and similar low-priority bugs. Nothing big.

PC-gaming is dead... (RLY?)
OK.., how and where did the proclamation of "PC-gaming is dead" come round?
People, please... what kind of platform do you think games are created on?
Seriously... that's just, a completely new level of ignorance.
Consoles? Eeeeeh, they will co-exist, and probably evolve, but they will NEVER crush, or even replace PC-gaming.
EVAH...
I would rather believe this article when it comes to the current gaming-climate: http://www.techradar.com/news/gaming/consoles/console-gaming-is-dead-everything-good-is-happening-on-pc-right-now-1260162

ยต-cloud, so far...
3 years - 24/7 operation (2011-2014), and still running like a well-greased steam-engine :P everything runs some form of Linux ;) open standards - open systems :D all the way.
I've never had OP processing-capabilities before, especially at my own complete personal disposal (20+ years of computing-experience), until now :P 3,5 years later (that's including half a year of planning before starting the build).
Never going out of CPU-time, practically never overflowing (swapping) the system memory. And rarely even getting into CPU-loops (unless I'm doing some risky low-level programming for lulz).
I am proud to say that my domain is fully OSS-operated ;) :D
Network-wise, I have separated internal traffic into separate VLANs, mainly for layer-2 separation of different protocols and various traffic-types, like: Internet-traffic, incoming web-server traffic, VPS' Internet-traffic, management sub-net and iSCSI sub-net.
iSCSI even runs on separate NICs (on both storage-box and server), through it's own switch-block and separated sub-net, to prevent interference with other packets running on high-traffic sub-nets (like Internet-access).
Outgoing traffic (and incoming of course :P) is pumped through a VPN / Firewall network-box that has a firewall-throughput equal the total speed of the FTTH Internet-uplink connection ;D

A little side-note
To whom it may concern (you know who you are):
I started this blog for myself, as a kind of rolling-release diary / project-roadmap for my digital escapades.
I did NOT start the blog to attract shallow attention from hipster blog-readers, to push up statistics and visitor numbers, that was simply an entertaining and completely unseen side-effect.
When posts seem to be aimed at specific people, it is usually friends and / or family. Certain (other) people read the blog from time to time (and enjoy my rants to a certain degree), but it's not for everyone...
Any suggestions sent to me either by commentary or e-mail, on how to:
- broaden my audience
- get my visitor-statistics up
- change my blog to satisfy reader-interests
I do, however appreciate constructive criticizm and corrections ;)
I don't embed ads, track visitor interests, publish general-interest posts or earn money on this blog.
It's main purpose is not to contend in the attention-seeking, popularity-contests of the pinkies.
If anything, one of it's purposes would be to inform people of tech-matters. And generally just to show that technology can be fun (sort of :P).

NVIDIA stable/current
Woke up this morning, logged onto my workstation, realized nothing was behaving like it should.
Windows were tearing, whole screens were acting weird and I could not for the life of me surf the web with ANY browser I had installed. Which wouldn't be as irritating right then and there, if it wasn't for the fact that I needed to log into my online bank-account!
After an hour of aggravation, and another hour of testing with different graphics-drivers (NVIDIA stable/current), I found out my GPU (GeForce GT520) did not play well with the new experimental driver from NVIDIA.
sudo apt-get purge nvidia-current && \
sudo apt-get install nvidia-current
The above command resolved my issue by removing the bleeding-edge nvidia-driver and replacing it with a version-rollback (v319 instead of v331).
After a warm reboot everything worked perfectly! Spotify, Steam, Chromium and Thunderbird all started, worked and rendered like they should.
Dunno if I'll be re-installing the experimental driver any time soon. Time will show.
For now, the stable current-version does it's job.
Who knows, maybe the time is right to replace my NVIDIA GeForce card with a more recent AMD Radeon HD card? I'm quite sure I read somewhere that the Catalyst Linux driver had ironed out most of the major bugs (fullscreen HD crashes / screen tearing / etc.).

Steam for Linux...
Ok, time for a little summary of my "Steam for Linux"- / "SteamOS"-testing:
All of my current Linux-based Steam-games (50 out of 67) run flawlessly on both Linux Mint v13 (with backports) and Ubuntu Desktop v12.04 (vanilla).
- They do not require a top-of-the-line gaming graphics-card.
- They (also) do not require vast amounts of memory (8GB will do fine).

SteamOS is still in it's early testing-stage(s). You basically have to posess a fair amount of advanced Linux-tinkering skills to be able to utilize it properly, but things are progressing. There are some automated versions being made (custom ISO-images) to let anyone install, test and even debug it on hardware (without the earlier requirement of a EFI-capable motherboard, you can manage with a BIOS-version now).
New (old) mobile carrier...
My previous carrier (NetCom AS) was better at customer relations and support, but they've gone downhill after they were bought up by another major scandinavian service provider (Telia AB, Sweden).
NetCom touted for a long time about their 4G-network coverage, and for some time (while they had few customers connected to their 3G- / 4G-nets) they delivered quite good HSDPA-connectivity. But after a lot of people migrated from various carriers over to NetCom the last few years, their remote end-networks (small towns) suffered as the base-stations at selected areas couldn't handle the traffic-surge very well (few, if any, of the base-stations had optical WAN-uplinks).
This had a negative effect on my SSH-connections from my smart-phone / tablet, and used to cause a lot of spontaneous traffic-drops and disconnects.
To my surprise (as Telenor is the biggest ISP in Norway, with a grand total of approx. 140 million mobile customers worldwide through various daughter-companies in Russia, parts of Europe and India), I got a minimum of 12-14Mbps via HSDPA (3G), whereas NetCom could only offer (at max) 2-3Mbps.
To my delight, I haven't experienced a single SSH-related disconnect on any of my 3G-devices :)
Telenor FTW!

LG Nexus 4
I have to say, I have never had a phone I fell in love with this fast :) if this one breaks, I'm surfing online surplus-stores to find the exact same model again (unless there's a new better Nexus-phone).
It has some pretty impressive specifications:
- Qualcomm Snapdragon S4 Pro (APQ8064, 1.5GHz quad-core)
- Adreno 320 GPU (OpenGL ES 2.0)
- 2GB memory
- 8GB / 16GB internal storage (I got the 8GB-version)
- True HD IPS Plus 4.7" 1280x768 px display
Only caveats so far is that the battery is fused into the chassis, there is no way to change the battery, you have to get a new phone. And it has glass on both the front and back, so it's recommended to buy some kind of rubber-shielding or (as I bought) a bumper-case to click onto the edge of the chassis.

sshlog v1.6
Bash scripts for generating and viewing simplified SSH access-logs in a console.
My reason for creating sshlog (and consequently sshloglist and sshlogviewer) was to have an easily available command-line toolchain, capable of generating and viewing simplified SSH access-logs through a console (plain-text interface, usually SSH+Bash).
https://code.google.com/p/sshlog/
sshloglist is used to generate a box-based, selectable list of the logs already present in the ssh-logs directory, when a log is selected, it pipes the selected list filename to sshlog-viewer.
https://code.google.com/p/sshlog/
sshlogviewer is a box-based log-viewer interface. It prints the content from a given sshlog (from a datastream piped directly by sshlog, or given as a filename at the command-prompt or by sshlog-list). It then lets you flip through the sshlog-pages with the Page Up and Page Down keys. Press 'q' to quit (using less, if dialog is not installed) or spacebar/enter to press the "OK" button (using sshlog-viewer + dialog).

AMD + SoC + ARM
The previous post was about AMDs current bugdet-line mobile processors. Before that, I posted (in Norwegian) about their plans for future mobile solutions.
They are basing their new budget-line / mobile processors on the "Jaguar" microarchitecture (the pre-decessing C- and E-series are "Brazos" based), and will sport 64-bit dual- or quad-core ("Bobcat" x86-cores) with integrated Radeon 8000 graphics (80-core GPU), significantly outperforming any "Atom"-chips with integrated graphics from Intel.
The new "AMD Embedded G-series System-on-Chip" sets will be made in two versions (or architectures): x86 and ARM. Determining which architecture a chip is based on, is as easy as looking at the CPU-logo; the ARM-version will have an "A" in the lower right corner of the logo and the x86-version will have an "X" (as shown in the picture below).
AMDs "Embedded G-series SoC" seems to be direct competition against Intels "Atom" budget-line. CPU-vendor competitiveness is, as we all know (at least the one's paying attention), a good thing :-P
It will be exciting to see how the combination ARM+Radeon will operate and behave performance-wise :-) since I've been an avid embedded (ARM ) fan for years, it'll also be quite interesting to see AMD play with both CISC- and RISC-based designs in the same series.

Ultrabook for my sister
I was recently asked by a family-member to look for a decent study-laptop for my sister. I'll admit I was kind of thrilled. I was playing around with the idea of finding a low-budget laptop, with decent specifications. Having done a machine-architecture report for school (x86/x64) last year, I had become thoroughly aware of what AMD has been doing lately.
I have always been a fan of AMD. Mainly because of their support for hardware-hacking (NOTE: this voids any warranty) and / or chip overclocking (in many cases also voids any warranty), and their clever innovation of techniques (amd64/APUs). And last but not least, their open and full support of FOSS.
In my report, I wrote about AMDs budget-line processors; the "Fusion" C-series and E-series, direct competitors to Intels "Atom" budget-line processors. In fact, the C-chips match similar Atom-chips in both TDP (Thermal Design Power) and clock-frequency (GHz). Whereas the E-series is higher clocked, resulting in a higher TDP, but also making it more similar to an Atom-chip system paired with a dedicated GPU (e.g. ION2).
My sisters computing-needs do not require massive number-crunching abilities, but it shouldn't be sluggish in operation either, so I went for the high-end mobile-solution: AMD E-450 (codename: Zacate) APU (Accelerated Processing Unit) used in a 13,3" LED-screen Asus model U32U laptop with 4GB DDR3 RAM.
The AMD E-450 is a 64-bit dual-core ("Bobcat" low-power x86-cores @ 1,65GHz) processor with an integrated Radeon HD 6320 GPU on the same die (which AMD markets as a so-called APU-chip), with a total TDP of 18 watts.
(The basic idea behind this type of system, is that: the stripped, low-power x86-cores (x2) does most of the general-purpose processing, but, hands over floating-point unit calulations to the GPU-cores on the same die, thereby eliminating both process load-balancing and CPU-GPU inter-communication delays.)
Asus product-link:
https://www.asus.com/Notebooks_Ultrabooks/U32U/
First boot took a few minutes, Windows always does at "first-boot".
Installing Microsoft Office 2010 (with the help of an external USB 2.0 CD-ROM drive) actually didn't take all that long, and it ran like a dream.
This was my first ultrabook-like experience, and I must say, I am impressed :-) I want one! Strictly speaking, the U32U does not fit the ultrabook-specification (being an Intel-trademark, and the U32U being AMD-based).
Personally (speaking as a poweruser), I would probably cram at least 8GB of RAM into the machine afterwards. And replace the 320GB HDD with an SSD for both system-speed and machine-weight. But for my sister, it was perfect! :-)
I might also add that I actually own two machines with Atom-processors, and the E-450 blew them both away on graphics and processing-power.
Edit:
I had to add a total of 8GB DDR3 RAM modules to the machine. She complained that it was getting sluggsish after a period of time. I had apparently not anticipated her usage-patterns good enough. 4GB of RAM was a little weak, especially if you want to run office-suites and similar resource-hogging software.
Funny comment :-P
This was a response to "Correct me if I'm wrong" posted by an irrate Linux FUD-er. ( http://www.zdnet.com/six-open-source-security-myths-debunked-and-eight-real-challenges-to-consider-7000014225/ )
Prove that Linux gets hacked. It's something never done here.
If you feel that strongly about it, post how and where you got hacked. I'm waiting.anonymousTest the theory yourself
Get a box and harden Windows, use ANY anti-malware you like.
Get a box and install any Linux distro, any of them, pick the weakest one you can think of.
Go look at any web site you like with Firefox, Opera or Chrome on both ... NO IE (not supported on Linux).
(hint: adult content and gaming sites that are 2nd or 3rd tier are reportedly famous for infections), try google searching "most dangerous web sites".
The rules of the game are:
* only following links or using the back button icon of the browser are allowed
* if windows pop up you are not allowed to touch them anywhere (including the X to close).
* if the back button is not usable or the browser is non-responsive, close the browser with task manager.
The object is to visit infected sites and return without touching anything.
See which system is left running after 1 hour.
Please report your results HONESTLY.
* ( ... no clicking (X)
* If the browser locks up ... use the "task manager" to kill it.

AMD, SoC og ARM.
AMDs nye satsing pรฅ bรฆrbare enheter heter "AMD Embedded G-series System-on-Chip" (kort: SoC), basert pรฅ AMDs nye Jaguar mikroarkitektur.
AMDs pressemelding:
http://www.amd.com/us/press-releases/Pages/amd-embedded-gseries-2013apr23.aspx
Det er nok den nye strรธmgjerrige serien som skal konkurrere direkte med Intels "Atom"-serie (benyttet i NAS-bokser, nettbrett, mini-laptoper, osv.).
Brikkene skal lages i to arkitekturer: ARM og x86. Om brikken er ARM- eller x86-basert ses nede i hรธyre hjรธrne av logoen hvor det blir trykt en "A" for ARM, og en "X" for x86 (bildet ovenfor viser en x86-basert brikke). De vil ogsรฅ komme med to eller fire kjerner som vil kjรธre pรฅ en klokkefrekvens mellom 1 til 2 GHz. Grafikkmessig stiller AMD seg bedre enn Intel. Disse brikkene har integrert GPU basert pรฅ Radeon 8000 som i fรธlge AMD gir opptil 5 ganger bedre grafikkytelse enn tilsvarende "Atom"-prosessorer fra Intel.
Personlig liker jeg veldig at AMD leker med รฅ blande CISC / RISC i en brikke-serie, og det vil bli voldsomt spennende รฅ se hvordan brikke-kombinasjonen ARM / Radeon vil oppfรธre seg i bruk.

WinSCP
been in heavy use over the years...
I hadn't given it much thought, but I have been using ONE Windows-application quite extensively over the past years. WinSCP.
For a simple-faced filemanager, it has many uses. But it's main feature is to connect to SSH / SFTP / FTP servers, handle files locally / remotely, transfer files, etc. A networked client-server file-manager application.
Before the early years of 2000, there were no decent graphical file-managers for cross-platform transfers and handling. Especially not with proper support for the Secure SHell v2 protocol.
WinSCP had this from the beginning (mainly with the scp program at first, then the SFTPv2 protocol. more recently WinSCP opts for switching to SFTPv3 protocol if available, for added security).
I can't recommend this program enough for it's easy transfer, handling and other file-related operations. I have never had any serious problems with it. It just works, and it works pretty damn good too.
It's interface is a beautiful interpretation of earlier, rather similar :P command-line designer guidelines.
You're wrong and probably never worked for a software company.
Software versions are charactized by version numbers, in my case, when I worked for Bentley Systems, a version was designated by numbers like 05.07.01.22.
Software, like Firefox makes versions for Windows and Linux among others. Basically the core parts of the program operate in the same manner and the API is different to work on Linux and adjustments are made for libraries, directories, etc.
The dirty little secret here at ZDNet and among the shills is that they blame an application for allowing an intrinsic problem or vulnerability with the OS to be accessed. Shills, Ed, and ZDNet are great at blaming the application, such as Chrome or Firefox for the problem and not addressing the core Windows vulnerability. Then, they read documentation and without knowing anything about how things are done, blame the Linux counterparts, because they are listed.
The problem is that items present in the application allow the core Windows vulnerability to be used to infect Windows. The application issue may also be present in the Linux version, but because Linux is so much more secure than Windows, there is no problem or infection with Linux. The only way Linux could be infected is if the malware could read the mind of the user and get his password.
Developers review the Windows version issue and make adjustments so it does not allow the Windows vulnerability to be addressed and also make the change across the board to all sister versions to maintain consistency. Because you are naive and see Ubuntu listed as affected, it does not mean Ubuntu ever had a security issue at all, the Ubuntu version is just having the code changed for consistency. In other words, no application for Windows is ever going to fully prevent all the Windows critical flaws from being accessed. Those application characteristics causing the Windows issues may be present the Linux version, but can't be used to attack Linux, but are being changed anyway. In most cases, the change may be an operating improvement and be more efficient.
It's so silly to ZDNet pull the same BS over and over again, year after year. If you want to believe it, you are only following the ZDNet propaganda trail, Do yourself a favor, pour yourself a strong one, and install Ubuntu or Mint on a second machine, run it as a Live DVD, or install it as a dual boot and your primary computer. Then, install, Chrome, Opera or any other open source program you like and try to get infected. Then come back here and post the Website and how you got infected. That's something that no one, in all these years of accusations has ever been able to do. Once you see that you don't get infected you;ll begin to see how ZDNet twists information and is just a stooge for Microsoft.
As far as you referencing Linux Torvalds and the linux.com issue it was related to stolen passwords. Anyone who gets poorly secured passwords an attacks a system can't be stopped. Most times the admins are storing their login information on a Windows box, that gets easily hacked by a zero-day or a crafted emai that allows access. Remember the big ZDNet push for articles about Google, which runs 100% Linux getting hacked? Well, two Chinese employees were storing data on a Windows notebook and it easily got hacked. Since then, Google forbids employees from using Windows or work. you don't hear about that anymore here, do you? Forbidding employees to do company work on Windows is the single most important any manager can make.
If you dig deeply into these articles against open source and Linux, you will find, as I have, that the core problem is Windows and you will see a critical update down the road, at a later time to silently correct the Windows problem. But that is never brought up here.
