Responding to random blog posts. Today: 2009: software installation in GNU/Linux is still broken -- and a path to fixing it

While ran­dom­ly click­ing to­day I saw this ar­ti­cle with the fun ti­tle of "2009: soft­ware in­stal­la­tion in GNU/Lin­ux is still bro­ken -- and a path to fix­ing it" by Tony Mo­bi­ly.

As I don't have an ac­count at FSM and don't in­tend to open one to­day, I will post a re­sponse here, where noone will ev­er no­tice it. Be­cause that's how self­-­con­fi­dent I am. I warn you, this re­sponse is full of proof-by-asser­tion and in­valid gen­er­al­iza­tion­s, but hey, it's opin­ion.

It starts with an in­ter­est­ing claim:

And yet, soft­ware in­stal­la­tion in GNU/Lin­ux is bro­ken. No, not bro­ken… it’s ter­ri­bly bro­ken. Why is that, and what can be done to fix it?

I in­tend to show how there is one lit­tle prob­lem with that state­men­t: re­al­i­ty. As in "what's the most suc­cess­ful soft­ware de­liv­ery plat­form for 'nor­mal' users in 2009, and why that mat­ters here" re­al­i­ty (hin­t: it's not win­dows, it's noth­ing on a Mac).

I mean the iphone, and its App Store. And what he is propos­ing is aban­don­ing some­thing that works a lot like it, and go back to the cave-age "down­load this from the ap­p's site" mod­el win­dows us­es.

He de­scribes the usu­al in­stal­la­tion pro­ce­dure, be it ap­t, yum or pac­man, al­most all dis­tros do the same thing nowa­days, then starts de­scrib­ing the prob­lem­s.

  • Users need to have root ac­cess in or­der to in­­stall a piece of soft­­ware; no per-us­er in­­stal­la­­tion is al­lowed

This would have been a prob­lem in the old days of shared com­put­er­s. Nowa­days, you are root, or (in some cas­es) root's mom. All mod­ern dis­tros use su­do so you don't need root ac­cess, you just use your own pass­word (or no pass­word at al­l).

So, this is a non-is­sue.

  • It’s very tricky to in­­stall sev­er­al ver­­sions of the same piece of soft­­ware. Just think of the poor graph­ic de­sign­er who needs to in­­stall sev­er­al ver­­sions of Opera and Fire­­fox; Users are stuck with the piece of soft­­ware in­­stalled sys­tem-wide;

How do you in­stall iFart 1.0 and 2.0 in an iphone? Can you? Spe­cial users (like graph­ics de­sign­er­s) should be pro­vid­ed by spe­cial so­lu­tion­s, like por­ta­ble fire­fox. Think there's a need for it? Go ahead, it's maybe one day of work.

  • The soft­­ware needs to be down­load­­ed from the of­­fi­­cial re­pos­i­­to­ries. Well, it does­n’t need to, but an av­er­age us­er wants to stay well away from un­of­­fi­­cial re­pos­i­­to­ries for tech­ni­­cal rea­­son­s;

The iphone soft­ware needs to be down­load­ed from the app store. That has not hurt any­one (other than app de­vel­op­er­s, I mean)

  • In some cas­es (e­spe­­cial­­ly when the us­er adds re­pos­i­­to­ries or in­­stalls pack­­ages di­rec­t­­ly), the de­pen­­den­­cy-check­­ing mech­a­nism of­ten fails and users end up with cir­cu­lar de­pen­­den­­cies. They are nasty;

I have not seen a cir­cu­lar de­pen­den­cy since 2003. But hey, maybe they do ex­ist. In that case, don't do that.

  • A piece of soft­­ware is bound to a spe­­cif­ic dis­­tri­bu­­tion, and — what’s worse — to a spe­­cif­ic ver­­sion of that dis­­tri­bu­­tion too. It’s not triv­ial to in­­stall Open­of­fice 3.1 on Ubun­­tu 8.10. You can ar­gue that you can in­­stall the bunch of .deb pack­­ages from OpenOf­­fice’s web site. Tell that to your grand­­moth­­er or your av­er­age in­­ex­pe­ri­enced com­put­er us­er.

Some iphone apps will not work with­out the 3.0 firmware. So­lu­tion? Up­grade your firmware. How's that dif­fer­ent in Lin­ux?

  • It’s not triv­ial to “give” a pro­­gram to a friend. To the end user, giv­ing a pro­­gram to a friend should be as sim­­ple as drag­ging an icon on­­to a mem­o­ry stick; in­­stead, files are scat­tered all over the sys­tem.

It'­sev­en sim­pler than that: here, let me give you rst2pdf for ubun­tu: "Tony, in­stall rst2pdf, it's in 'u­ni­verse'". I don't even need to give you a flop­py disk or what­ev­er kids use these days.

Oh, and "how do you give some­one an iphone ap­p?"

Then, he pro­pos­es so­lu­tion­s, which I think are worse than the sta­tus quo:

  • Users should be able to in­­stall soft­­ware even with­­out be­ing root

Users are root, or root's mom. This is not a prob­lem.

  • Users should be able to in­­stall dif­fer­­ent ver­­sions of the same soft­­ware im­­mense­­ly eas­i­­ly

The on­ly way to do this is to make ev­ery­thing stat­ic or freeze the sys­tems li­braries.

Do this for "portable" ver­sions of spe­cif­ic apps if you wan­t. Don't make the sys­tem suck, please.

  • Users should be able to run ei­ther their own ver­­sion of the soft­­ware, or the one in­­stalled on the sys­tem (if any)

Fine by me. OTO­H, how do you do that on an iphone? You don't. Please, stop di­verg­ing from what is work­ing in 2009.

  • It should be pos­si­ble to down­load and in­­stall soft­­ware even though it does­n’t come from an of­­fi­­cial re­pos­i­­to­ry

Again, the iphone does­n't, and noone cares. If you care, you are not the nor­mal us­er you claim to ad­vo­cate.

  • Soft­­ware just needs to work — un­changed — even if it’s a bit old and it’s run on a new­er dis­­tri­bu­­tion

Yes, I want Quick Shot for iphones with 3.0 firmware!. Again, al­most noone cares, ex­cept app de­vel­op­er­s.

You are act­ing like a Lin­ux user, dude!

  • It should be pos­si­ble to “give” a piece of soft­­ware to a friend by sim­­ply drag­ging an icon on­­to a mem­o­ry stick

Just tell the guy the name of the app al­ready!

All this is true with Ap­ple’s OS X. They got soft­ware in­stal­la­tion just right — al­though a few pro­gram­s, late­ly, seem to come with an ug­ly in­stal­la­tion process.

Noone choos­es a mac for this. They choose it be­cause it's pret­ty, or be­cause they are told they are bet­ter, or what­ev­er, but any­one ac­tu­al­ly say­ing "hey, on a mac I can give you Of­fice by shar­ing this 800MB dmg!"? Not on­ly noone does it, it's freak­ing il­le­gal.

Be­sides, you give the dmg to your friend, and 92% of the time, your friend has win­dows or Lin­ux and can't use it. So your chance of suc­cess is about 8%.

Imag­ine if it on­ly worked if your friend's com­put­er was an Ac­er? There you would have a 10.5% chance! (see here) Noone would say that's good!

No, sharin apps like that is not the prob­lem.

Please, dear lin­ux dis­tro de­vel­op­er­s, look around you, and see what works in 2009.

Amaz­ing­ly, what works looks an aw­ful lot like what we have been en­joy­ing since 1998 or what­ev­er, so let's en­joy it and make it bet­ter, in­stead of try­ing to be­come like a mac, or like win­dows, old style plat­forms in the age of the smart­phone and the net­book.

UP­DATE: you can check more com­ments about this sto­ry in red­dit, lx­er and OS­News.

AAFigure in rst2pdf

As of to­day, rst2pdf sup­ports Chris Liechti's awe­some aafig­ure.

What does it mean? It means you can put this in your doc­u­men­t:

+-------+       +-------+
|   A   |------>|   B   |
+-------+       +-------+

And get this (and as a PDF draw­ing, not as an im­age, so you can copy the text from it):


So it's an awe­some way to add sim­ple di­a­grams to your re­struc­tured text doc­u­ments that look good in plain tex­t, on the we­b, and on PDF.

Aafig­ure can cre­ate lots of in­ter­est­ing draw­ings, check their docs for ex­am­ples here

It cur­rent­ly re­quires aafig­ure from bzr (0.3 won't work).
