You arrive at the airport, in a hurry as usual. You look up at the flight departure screen and it says “A fatal exception OE has occurred at....The current application will be terminated...” You know the rest. This is the epitaph in blue that Windows issues for every application it terminates, also known as the Blue Screen of Death, or BSOD.
Lately Matt Michie, a writer and Linux hacker, has been keeping a growing gallery of public BSODs at his site (http://www.daimyo.org/bsod/), which ranks high among the many thousands of pages that show up in searches for “BSOD” or “Blue Screen of Death”. From what we can tell, these include a giant Las Vegas billboard, an airport flight schedule display, an ATM machine, a casino game, a building marquee and public signage of various unknown, but not unembarrassing, sorts.

In the June 1996 issue of Linux Journal, we wrote that in addition to support for IA32, Amiga, and Atari, Linux is “being ported to several more platforms, including Alpha, ARM, MIPS and PowerPC.” Five years later, not only are these supported but also SuperH, SPARC and UltraSPARC, the S/390, VAX, PA-RISC, IA64, ColdFire, DragonBall, ETRAX, i960 and a host of others.
At this point it almost goes without saying that the predominant web server is Apache, which has had the top market share across all domains since early 1996, holding at better than 60% for the last year—according to Netcraft who has been studying the matter since September 1995. Back then the top server by a huge margin was NCSA's, which flatlined at approximately zero in 1999.
Apache is still doing fine, but it dropped by 1.29% in January of this year, Netcraft reports. Microsoft's IIS gained 1.82%, and Sun's iPlanet, the third-place server, dropped .29%. Both Apache, and Microsoft gained in absolute numbers. Netcraft found 16,207,982 domains served by Apache and 5,903,512 served by Microsoft. But there were other developments behind those details. Netcraft reports,
The relatively static market share for Microsoft on the Web as a whole contrasts sharply with its progress in our companion SSL Server survey where Microsoft makes consistent and relentless gains, month after month, and now accounts for 49% of the sites performing encrypted transactions on the Internet. Arguably, Microsoft's applications have made the difference, with there being no straightforward alternative to Microsoft's Commerce Server in the UNIX world.
Netcraft also reveals that PHP is being adopted at an extremely rapid pace:
The PHP module is compiled into the Apache server on over five million web sites, or approaching 40% of all Apache sites. Although PHP will only be in use on a fraction of these sites currently, it is regarded as easier to program than Perl or JSP and has created a broad developer community in a relatively short space of time. PHP, together with MySQL and Apache, has become the de facto way of developing web applications in the Linux environment, in a similar way to the IIS/ASP/SQL-server combination in the Microsoft world.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
