Debian: Unrelenting Quality

I have mentioned before that I chose to cover Lubuntu, because Dan at PPC Luddite did such an amazing job writing about Debian.  I don't like to leave good software unwritten about, but if Lubuntu is good, then Debian is great.  I can no longer contain my unrelenting love for Debian, and its unrelenting quality standards for its software, and anything they package with it.

Debian is the poster child for what software standards should be, which is why so many distros are based on it.  The Ubuntu's, Mint, Crunchbang and Finnix (just to name a few) are all born from Debian code.  Debian have been setting the benchmark for quality, clean, reliable code since the mid 90's, and continue to do so today.  In 20 years there have only been 7 stable releases.  It's because when they release a stable build, they truly stand behind that.  The gap between 6 and 7 was quite short by their standards.  The project actually has about 1000 official developers overall.


This is pretty much how Debian developers operate:

1. Test
2. Test some more
3. Test some more
4. Test some more
5. Test some more
6. Check everything over again and again then test some more
7. Test some more
8. Test one last time just to be really really certain.


While these practices keep the stable build a good mile from the bleeding edge, the end result is stable, secure, never fail you code.  There is a reason Debian is usually a top choice for servers.   If you really desire the bleeding edge kernel and default apps then you can simply install Debian testing.  I honestly have more faith in their testing builds than the finals of pretty much every other distro.

Debian PowerPC is also about the last Linux distro with official support on the architecture still, and there are no signs of it ever stopping. Another thing Debain PowerPC does is allow apt to work perfectly.  In my experiences the Ubuntu's and other distros mess this up at some level.  As someone who prefers some command line on a daily basis this is a big selling point for me and I know it is for Dr.Dave also. 

I have been doing a lot of playing around and testing the newest stable release of Wheezy (7.1 currently) and several different GUI.  The memory usage difference between the various environments is quite significant.


Here are the memory usage totals for each GUI after simply logging in, and with nothing else running:

GNOME 3 - 188 MB

XFCE - 167 MB

Openbox - 101 MB (a bit higher than usual)

Fluxbox - 93 MB

LXDE - 81 MB (I have gotten it down to 69.8 MB now thanks to some trimming)

The system has 1.5 GB (1536 MB) RAM


LXDE is the reining champ, and is so much easier to use for Linux newbs than Openbox or Fluxbox, which use more memory.  I started with the Debian LXDE image and then installed the other enviroments.  LXDE, Fluxbox and Openbox fly while GNOME and XFCE sputter a bit on my G4 1.0GHz Sawtooth testing system.  GNOME and XFCE are still very usable but they simply can't compare performance-wise.  There is also a KDE offering but I have never used it with Deb7.  While KDE is very capable it's one of the most bloated GUI.  It's almost as bad as Unity in terms of system resource consumption.

I will be writing a lot more about Debian 7 soon but I wanted to get out some early observations on Wheezy stable which is only about a month old.  


A couple screens:

They all use the standard Debian installer, which is not a GUI like Lubuntu.  Don't worry though, there are no commands you need to know.  All you ever have to type are usernames and passwords you want.  Tab selects actions, arrows move selections, space makes selections and return/enter executes.  It's actually quite simple to use and should only take a person one use to learn.


It's good.  It's great.  It's all it should be.  It's all any OS should be.  It's free in every sense.

I put Debian on equal ground with BSD.  It's one of only 3 Linux distros I would say that about.  The other two would be Arch and Gentoo, but even they can't touch Debian in my mind.

The twitter situation

Using twitter the last few days has been moderately interesting, but for the most part I have been reminded why I never used my personal account.  I'm pretty much officially over Twitter (again) already.

Another thing of note is that the amount of visitors we get is at least 300-500 unique ip hits per day, yet we only have gotten 21 followers in the first week.  This tells me that the regular readers here are pretty much as crotchety about social networking as I am.  After all, it does take a specific kind of person to appreciate the angle this blog comes from.  People who think like the Dr. and myself have no time for trends of any type.  While Twitter is one of the better parts of the social networking world, it's still part of a culture that I really cannot relate to.

I can't speak for Dr. Dave, but I am over Twitter already.  I may post something now and then or we may just agree to delete the account.

All I really care to spend free tech time on is writing for this blog and using Linux more.  That is what I shall continue doing.

I tried...  140 characters just isn't for me.  Far too limiting and I also tend to hate popular things by default.

This blog will not make any other attempts at social networking.  All that matters is the forward motion of PowerPC and you can get that right here.

Note:  The twitter account has now been deactivated as of June 21.  


Side note

Debian 7 LXDE is amazingly good BTW.  The stable release was introduced in the recent past.  It puts Lubuntu to shame in terms of pure functionality and reliability.  Debian is not as bleeding edge with the kernel and default app versions as Lubuntu is but it's as rock solid as you can get. 

More on that soon.

The devolution of computing

I have been reflecting a lot lately about the state of computing today.  The state of both the development and the users, along with what drives the majority of people from both groups.  For myself, and anyone who prefers to compute from the drivers seat, the state of things is bad on almost all fronts; at least in terms of mainstream computing.

Computing at a high level in the 70's, 80's, and even the early 90's was much better, because any other users around you were at a high level also.  Almost everyone had real capability to compute far beyond pointing and clicking.  Before the GUI existed you literally had to know command lines, and have a catalog of them in your head at your disposal whenever needed.  There were no guides on websites to copy/paste commands from, which is the peak of text computing skills these days for the pointy clicky imprisoned types.  Even with how far the GUI has come, there are still many capabilities that even the most robust OS's UI would lack.  I have mentioned before that only about 60-70% of the full OS X capability is found in its GUI.  Everything else is accessed from the command line.  It is based on BSD after all.  Text/terminal use is the actual human language of computing, not pointy clicky.  A GUI can only do what it gives you options to click on.  A GUI is essentially just an OS hand holder.  All you need is basic hand-eye coordination, and all it's doing is typing the commands for you while you click away.

The user friendly obsession of MS and Apple software over the last couple decades has truly dumbed down the average user a great deal.  The sad truth is that most people only have the capability to point a mouse, and type in whatever language(s) they're literate in.  The even sadder truth is that some actually mistake this for having computer skills.  Some even go as far as to think such skills qualify them to "help" someone else by sharing their "experience".  Experience based on nothing.  When you can only compute at the level of a person that many would consider computer illiterate, then you have no experience to give. 

I'm sorry, but moving a pointing device around, and being literate in your language, is no type of computer "skill".  People who compute at that level need to keep their devolved computing culture to themselves, and focus on learning new ability, rather than trying to spread devolution.

The devolved ones are on some insane mission to spread their 'newer/faster hardware is always better' illogic, and follow Apple or MS blindly.  No one needs help to do such things, because all it requires is no thought.  Anyone can do that.  Give people true technical insight, not what they can get from a wikipedia or google visit.  If that is where you're getting your "experience" from, then you've turned yourself into a fake, and a redundant fake at that.  Pretty shameful.  I assume the goal was never to be a double negative, but that is the end result for some of you.

The people who spread such things know who they are and they need to stop.  Your blind follower no skill thinking is a cancer to anything that resembles good information.  Stop it please.


Lastly

I am sorry if some of this sounds mean, but every word I have written here is nothing but true.  The truth shall set you free, as the saying goes, is as apt with computing as it is with anything else.

Anyone who feels the desire to help others, needs to first do it with something they can help with.  Something you have legitimate experience, knowledge and insight with.  Not something you wish to, but don't yet have, those qualities with.

Don't pretend or devolve.  Learn.

Stop letting billionaires control how you compute, and keeping most of you in a limited and fearful of evolving type of state.  The very reason most of you don't want to evolve your computing skills is that you've been conditioned to think that computing and real brain work don't go together.  Essentially a mainstream/self-induced computer user lobotomy.  That is the true end result of decades of user friendly obsession by the mainstream.

We're still alive!

It has been over two weeks since our last post, and I wanted to mention what has been going on.

Dr. Dave hurt his back a couple weeks ago, so that has put him out of commission for the time being.  Please join me in wishing him well and hopes for a quick recovery.  I am sure he will be feeling better soon enough.

I myself have been more busy than normal with the OpenBSD project in it's last phase of development.  The last phase (for me at least) is dealing with every bug so this has left my life with zero free time.  In the next week to 10 days I will be 100% done the project and I already have a couple things in mind to write about.

OS X: Disable your v-sync

This post falls under the heading of "maybe not the single greatest idea in the world, but perhaps not the worst either." As we all know, Apple, in its infinite wisdom put some (ok, lots of) extra eye candy into OS X when it leaped from 10.4 to 10.5, and as a result you and all your loved ones took a graphics hit moving from Tiger to Leopard. Many argue the hit is minimal, and Leopard has so much more software and hardware compatibility that is more than worth it, a sentiment to which I firmly adhere. I do miss Classic, but otherwise Leopard...rocks. On x86 Linux I got used to doing all kinds of tweaks to get better video performance out of older machines, and one of the main ways was to set the v-sync to blank. Usually this was achieved by clicking a box deep within the bowels of compiz or editing a metacity preference file in nano. I'm no expert, but on LCD monitors I've read the benefits afforded by v-sync are pretty much a non issue. Lets face it, not many people are sitting in front of CRT's in 2013. If I've just deeply insulted Al in Syracuse, who is still in love with his 21inch ViewSonic purchased for $1500 (no, for real) from MacMall back in 1997, I apologize.

Honestly I never knew this tweak was possible in OS X. I thought Apple just locked all of that graphics stuff down tight to keep it away from those pesky end users. Then I stumbled upon a youtube video from a fellow PowerPC enthusiast, which sadly now seems to have been taken down or I'd post a link to it for reference. He had a bunch of good tips for improving graphics performance, most of which are well known, like using a 2-D instead of a 3-D dock, etc, etc. I was just about to stop watching when he showed viewers how to disable v-sync, and that caught my attention.

In order to perform this maneuver safely you'll need to have Xcode installed. If you don't have it its a free download from Apple, you will have to register as a developer and then sign over your first born child for ritual sacrifice, but once that's done its just a 300 MB download. You'll need an older version of Xcode, 3.3.1, as the newer ones are naturally Intel only. It is possible to do this in Text Edit, but personally I lack the intestinal fortitude to do so, see..I once hosed a Panther install fiddling around with a preference file in Text Edit. Xcode makes this simple, and for reasons probably only in my head it feels much safer.

What you want to do is go to your Hard Drive and open up the Library folder, then the Preferences folder. What you are looking for is com.apple.windowserver.plist, right click on that file, if you have Xcode you'll have the Property List Editor as an option, and open it with that. Now under Compositor look for "deferred updates" and set that to zero. Congratulations, you have just set your v-sync to blank on 10.5. There are some other settings which some turn off in there relating to Quartz Extreme and OpenGL but personally, I left those well enough alone.

Now anytime one fools around with system files, especially com.apple.plist's, bad things can happen. So, readers beware, and exercise all due caution. I followed the above steps and nothing bad happened, and, upon reboot I noted some definite improvements in overall window snappiness (such a technical term). Dock minimizations, even the hated "genie" effect were now lightning quick. The vicious tear I had passing my cursor over the dock in 3-D mode was also gone. Personally I use the 2-D dock so it wasn't a huge win for me, but overall this was a satisfying tweak.

On PowerPC OS X in 2013 its all about them little victories.

Help the Children Learn

Today someone, probably well under the age of 15, excitedly sent this Doctor a Youtube link to a recently posted video which they claimed showed a user how to install Flash 11.5 on a PowerPC Mac. It was of course no such thing, just a redo of the old "Facebook" hack which tricks some websites into offering up Flash video to your tired, unsupported, enough security holes to drive a (pun intended) Mack truck through 10.1 Flash plugin. I will not bother to repost the video or link here, as I do not like to spread bad or misleading information around the interwebs. But this does bring up a very important point. PowerPC macs are now so cheap they are an easy entry point for young mac enthusiasts eager to test out the OS X and Linux waters. I think that's great, but as with all things, kids need to be educated. So if you know one of these young PowerPC mac enthusiasts, don't be embarrassed, sit them down and give them the talk. Not that talk, this talk:

"Now young man (or woman), you need to know Adobe Flash was never a great piece of software on PowerPC. It was poorly written and never optimized for your machine. Today its old, and such a crap-tastic performer that will bring your otherwise excellent system to a screeching halt. It should be avoided on OS X PowerPC, at all costs. On PowerPC Linux this is a non issue, as there never was nor will there ever be Flash Player or Plugin. In this here year of 2013 you are far, far better using Flash workarounds. Here are few you can try..

Mactubes. Its been often said that this is an awesome piece of kit that keeps PowerPC Macs alive and well in the age of youtube. Make sure to set your player to Quicktime for best results, and have Perian installed as well. This makes many larger format flash files available for download and playback. The version of Quicktime that works with Mactubes well is 7.6.4.

Youview. This software pretty much does what Mactubes does, but unlike Mactubes you have to pay for certain features, like downloading. But it's handy to have in reserve.

Viewtube. This is a Greasemonkey script for Tenfourfox, it can be made to work with Safari as well by installing SIMBL and Greasekit. First go to Add-ons under tools and install Greasemonkey. You'll have to stick with Tenfourfox 17.X.X, as anything newer has plugins disabled and it just won't work. It works with some other sites besides youtube too, and the developer is a decent guy who is constantly improving and updating the script. It'll also use the Quicktime plugin, but right in the browser.

ClicktoFlash and ClicktoPlugin these work great with Safari (and Leopard webkit). By installing both you can do the same thing your trying to do with the Flash hack, that is, trick the website into believing you have the latest Flash installed. Many websites will then offer you up video. You'll have to click on the "QT Player" logo, and it will launch a standalone Quicktime player.

There are some other methods too, they're a little trickier, so try these ones out first. And remember... on PowerPC the only good Flash is no Flash. Tell all your mac loving friends."

It's a tired old cliche, but the kids really are the future, especially it seems when it comes to PowerPC macs...
