Dyslexia font

Filed under: Computers, Open source — Tags: , — zundel @ pm

A fiend brings to my attention news of a font to help with dyslexia: Dyslexie.

I forget not everyone lives in open source.

See OpenDyslexic:

We most easily read proportional text with serifs: quickly and smoothly — and go right past error.s We best edit mono-spaced text.


Mono-spaced text also works well for dyslexia.
A mono-spaced font with slab serifs may work especially well.

I do almost all reading and editing in dark green mono-spaced text on a soft yellow background (“#003300 #FFFFCC“), reducing glare and eye strain, and assisting acute vision spotting errors.

Fin by Keith Wesolowski

Want a ranch hand?

Meanwhile the most trumpeted “advance” of the last 10 years at the bottom of the stack is UEFI, which replaces parts of the system firmware… with a slightly modernised version of MS-DOS. It’s painfully obvious that the sole purpose of UEFI is to enable Microsoft to continue collecting royalties on every computer sold, a brilliant move on their part given the steady decline of Windows, but an abomination for everyone else. UEFI solves no problems for the operator, customer, or OS vendor. If anything, it creates more of them. There’s a better way to do this, but my central observation is that the solutions that would be better for everyone else are not those that would be best for the vendors: AMI, Microsoft, and Intel are quite happy with their cozy little proprietary royalty machine and have no incentive to engineer, or even enable others to engineer, anything better. The bottom of the stack is designed to serve vendors, not customers.

The net result of all this is that we have data centres occupying many hectares, filled with computers that are architecturally identical to a Packard Bell 486 desktop running MS-DOS long enough to boot a crippled and amateurish clone of Unix circa 1987…


I became a bicycle mechanic (by accident).
Not nicer people.
Not nicer businesses.
But more pleasant problems.

We, computer tech, have great tools. I love using them.
But the problems became old, repetitive, and uninteresting decades ago.
Didn’t matter if I developed or customized accounting software or recovered another server hosed by a rank amateur with all thumbs. Old uninteresting problems.

Bicycles have old repeated mistakes (stuff known a hundred years ago). I try to avoid those. But the day to day problems, what needs fixed, I enjoy.

Oh hell yes.

Some people just set it up better than others.

Seattle Rex vs. Apple: The Verdict Is In

Linux at 20

Filed under: Open source — Tags: — zundel @ am

Linux turns 20

IBM decided in 1999 that Linux was its friend. It correctly deduced that Linux would help it sell more hardware and services.

A good read

The quiet colossus:
The Linux kernel processes almost everything you touch.

Linux vulnerabilty

Filed under: Open source, Security — Tags: , — zundel @ am

Much in the news lately about a vulnerability in recent Linux kernels.

If you use a kernel before 2.6.39 you have no problem.
Stable distributions like Debian 6 and Ubuntu 10 have no problem.

Patches released and in the process of release for newer versions.

The kernel gets careful development, but still people do make errors.

Yet another argument for using stable distributions.

Hail, hail the end of menus

Filed under: Computers, Open source — Tags: , , , — zundel @ pm

Introducing the HUD. Say hello to the future of the menu.

HUD to replace menus in Ubuntu 12.04

I like Ubuntu again and eagerly await Ubuntu 12.04.

(And Mark’s affirmation of the centrality of the desktop heartens me.)

Menus offer discoverability: you can find out what a program does. But digging through them to issue a command takes time.

Experienced users issue commands from the keyboard rather than dig through menus.
They also start programs by typing using Gnome Do, KRunner, Spotlight, or Start menu search. Now Ubuntu brings type to execute to menus. Excellent.

Canonical has matched Apple with the quality and integration of Ubuntu.
They now out innovate Apple.

Et tu McAfee?

Filed under: Computers, Security — Tags: , — zundel @ pm

McAfee customers used to spread spam

McAfee’s Security-as-a-Service product Total Protection allowed attackers to use customers’ computers as spam relays.

They fixed it, but it should never have happened.
And only customer complaints brought the bug to their attention.

Wait, there’s more:

Critical hole in McAfee products still open after more than 180 days – Update

Great job auditing your code guys.
No one has every had any security problems with ActiveX?

Just don’t allow ActiveX on your systems.
Or McAfee.
Or …

Quis custodiet ipsos custodes?

Quis custodiet ipsos custodes?

There is no security through obscurity.

Symantec admits to more exposed code

Symantec’s code got taken, and now we have reason to doubt the security and usefulnes of their products, such as: Norton Internet Security, Norton Utilities, Norton GoBack, and pcAnywhere. We also have reason to doubt Symantec’s competence. If they cannot protect themselves, how can they protect you?

If you cannot publish the source code openly and still have a secure product, then your product is only as secure as your ability to keep it secret.

Symantec says hackers stole source code in 2006

Yet Laura DiDio, an analyst with ITIC who helps companies evaluate security software, said that Symantec’s customers should be concerned about the potential for hackers to use the stolen source code to figure out how to defeat some of the protections in Symantec’s software.

Many eyes make all bug shallow.

The bad guys now have the code.
If everyone had seen the code all along,
the good guys could have fixed the vulnerabilities in the code.

RSA got owned last year. Supposedly the very best at security had a very serious breach, the full consequences we don’t yet know and probably never will.

Then there’s the black farce of HBGary and defense and government attempts at security.

As I wrote in the takeaway: “If you need security, don’t use anything these guys mentioned.”

If you like the product on the supermarket shelf that implies it will make you look young and beautiful (whether cereal or shampoo) you’ll love the security in a box at Office Depot or for download. You can no more buy security than you can buy youth. Stop falling for the silicon snake oil.

Symantec discovered (admitted) that source code stolen in 2006 does compromise the security of their product. Symantec now recommends disabling pcAnywhere until they release a final set of updates.

Symantec publishes pcAnywhere security recommendations

In addition, an attacker with cryptography knowledge could conduct man-in-the-middle attacks on encrypted connections and create unauthorised connections to remote machines, thereby potentially gaining access to whole networks.

Microsoft Server 8 deprecates Windows

Filed under: Computers — Tags: , — zundel @ pm

Windows Server 8: The Microsoft Server Fork

Maybe someone at Microsoft has paid attention to the various Linux servers they’ve had over the years. Or maybe they have looked over the shoulders of Linux sysadmins (explains the draft).

Digging through windows, and dialog boxes, and tabs is a damned slow and frustrating way to administer a system.

but the center-thrust of Windows Server administration was encouraged to be PowerShell-driven, rather than through the maze of administrative GUIs that have been the mainstay of Windows Server versions for nearly two decades.

Yup, a damned maze.

Linux sysadmins working at a command line with command completion, history, tech manuals, environmental variables, and sophisticated screen management (screen, wmii, i3) at our fingertips get at lot more done is less time with fewer errors.

I get frustrated every time I have to work on Windows (so I don’t).
I can’t just type a few quick queries. Check a few settings. Issue a few elegant one line commands. Then check with a few tests. And call it good.

I have today’s billing log at hand. Latest item: Read scheduler error report. Check settings. All the settings. (“grep — /etc/cron*” can tell you a lot.) Make modification. 8 minutes. Try that with Windows scheduler.

(Having spent most of the day working in the shell, I’m getting a bit frustrated typing the blog: I keep wanting to hit the tab key to complete the word I type.)

While seemingly radical for Microsoft, there is much pressure on operational efficiency, coupled to increasingly complex control options and infrastructure character of the operating system.

So what’s left? What’s Microsoft’s competitive advantage?
Windows Server was always for those that came to it a bit late or were a bit young and couldn’t type. Programmers (not cut & paste) have always hated that point and click shit in our working environment. (Can I get a shell for Tivo? Hmm, Android api… One day when I have a spare moment… February 2015?)

But if you have to type anyway (there is much fretting in basements across America) why would you use Windows? Unix, then Linux is designed for efficient typing. We’ve been perfecting it for forty years. And security.

It’s Official: The Windows Server GUI Is (Slowly) On the Way Out

(Sitting here waiting for that server’s cron to pop another error. Deliberately made only one change.)

Linux distros compared

Filed under: Open source — Tags: , , , , , , — zundel @ pm

Enterprise Open Source Directory – Operating Systems
GNU/Linux Distribution Timeline


One of the few really long established Linux distributions, well known for stability and its curated repository of thousands of software packages, it has formed the basis of more Linux distributions than any other.
Capable of a stable configuration that updates and remains stable. Also easy to selectively use newer packages.
Used by many large institutions, with an extensive community of users and developers, well documented, with support readily available.
With a broad developer base and not dependent on any corporate sponsor or owner, change of ownership cannot occur nor vendor lock-in.


Based on Debian, Ubuntu refreshes it repositories from Debian every six months.
Ubuntu has done a great deal to popularize Linux. And has made some excellent server versions, especially the 10.04 long term support release. But recent focus on consumer appeal and a proprietary interface raise doubts about business suitability and support. The next long term support release coming April 2012 will answer some questions.


Not quite as long established as Debian, but the oldest commercial distribution.
The free community distribution openSUSE strikes a nice balance, not cutting edge like Red Hat’s Fedora, but instead stable yet current, with readily available support.
SUSE and openSUSE have the most extensive graphical administration tools.

Red Hat

Well known with a large installed base and good stability, but subscription fees make it expensive.


Red Hat’s free community distribution used for testing and experimenting. Not as unstable as it once was, but still not recommended for enterprise work.


A free clone of Red Hat.
With version 6 Red Hat changed the packaging of their source code which delayed the release of CentOS 6 by most of a year. Though it has a large installed base, the small number of developers raises doubts about its ability to keep current with Red Hat source and suitability for long-term deployment.
