(Repurposed CIX post.)
Don’t get me wrong. I like Apple kit. I am typing right now on an original 1990 Apple Extended II keyboard, attached via a ABD-USB convertor to a Core i5 Mac mini from 2011, running Mac OS X 10.10. It’s a very pleasant computer to work on.
But, to give an example of the issues — I also have an iPhone. It’s my spare smartphone with my old UK SIM in it.
But it’s an iPhone 4. Not a lot of RAM, under clocked CPU, and of course not upgradable.
So I’ve kept it on iOS 6, because I already find it annoyingly slow and iOS 7 would cause a reported 15-25% or more slowdown. And that’s the latest it will run.
Which means that [a] I can’t use lots of iPhone apps as they no longer support iOS 6.x and [b] it doesn’t do any of the cool integration with my Mac, because my Mac needs a phone running iOS 8 to do clever CTI stuff.
My old 3GS I upgraded from iOS 4 to 5 to 6, and regretted it. It got slower & slower and Apple being Apple, *you can’t go back*.
Apple kit is computers simplified for non-computery people. Stuff you take for granted with COTS PC kit just can’t be done. Not everything — since the G3 era, they take ordinary generic RAM, hard disks, optical drives, etc. Graphics cards etc. can often be made to work; you can, with work, replace CPUs and runs OSes too modern to be supported.
But it takes work. If you don’t want that, if you just max out the RAM, put a big disk in and live with it, then it’s fine. I’m old enough that I want a main computer that Just Works and gives me no grief and the Mac is all that and it cost me under £150, used. The OS is of course freeware and so are almost all the apps I run — mostly FOSS.
I like FOSS software. I use Firefox, Adium, Thunderbird, LibreOffice, Calibre, VirtualBox and BOINC. I also have some closed-source freeware like Chrome, Dropbox, TextWrangler and Skype. I don’t use Apple’s browser, email client, chat client, text editor, productivity apps or anything. More or less only iTunes, really.
What this means is that I can use pretty much the same suite of apps on Linux, Mac and Windows, making switching between them seamless and painless. My main phone runs Android, my travelling laptop is a 2nd-hand Thinkpad with the latest Ubuntu LTS on it.
As such, many of the benefits of an all-Apple solution are not available to me — texting and making phone calls from the desktop, seamless handover of file editing from desktop to laptop to tablet, wireless transparent media sync between computers and phone, etc.
I choose not to use any of this stuff because I don’t trust closed file formats and dislike vendor lock-in.
Additionally, I don’t like Apple’s modern keyboards and trackpads, and I like portable devices where I can change the battery or upgrade the storage. So I don’t use Apple laptops and phones and don’t own a tablet. iPads are just big iPhones and I don’t like iPhones much anyway. The apps are too constrained, I hate typing on a touchscreen “keyboard” and I don’t like reading book-length texts from a brightly-glowing screen — I have a large-screen (A4) Kindle for ebooks. (Used off eBay, natch.) TBH I’d quite like a backlight on it but the big-screen model doesn’t offer one.
But I don’t get that with Ubuntu. I never used UbuntuOne; I don’t buy digital content at all, from anyone; my Apple account is around 20 years old and has no payment method set up on it. I have no lock-in to Apple and Ubuntu doesn’t try to foist it on me.
With Ubuntu, *I* choose the laptop and I can (and did) build my own desktops, or more often, use salvaged freebies. My choice of keyboard and mouse, etc. I mean, sure, the Retina iMac is lovely, but it costs more than I’m willing to spend on a computer.
Android is… all right. It’s flakey but it’s cheap, customisable (I’ve replaced web browser, keyboard, launcher and email app, something Apple does not readily permit without drastic limitations) and it works well enough.
But it’s got bloatware, tons of vendor-specific extensions and it’s not quick.
Ubuntu is sleek as Linuxes go. I like the desktop. I turn off the web ads and choose my own default apps and it’s perfectly happy to let me. I can remove the built-in ones if I want and it doesn’t break anything.
If I could get a phone that ran Ubuntu, I’d be very interested. And it might tempt me into buying a tablet.
I’ve tried all the leading Linuxes (and most of the minor ones) and so long as you’re happy with its desktop, Ubuntu is the best by a country mile. It’s the most polished, best-integrated, it works well out of the box. I more or less trust them, as much as I trust any software vendor.
The Ubuntu touch offerings look good — the UI works well, the apps look promising, and they have a very good case for the same apps working well on phone and tablet, and the tablet becoming a usable desktop if you just plug a mouse in.
Here’s a rather nice little 3min demo:https://www.youtube.com/watch?v=c3PUYoa1c9M
Wireless mouse turned on: desktop mode, windows, title bars, menus, etc.
Turn it off, mid-session: it’s a tablet, with touch controls. *With all the same same apps and docs still open.*
Mouse back on: it’s in desktop mode again.
And there’s integration — e.g. phone apps run full-size in a sidebar on a tablet screen, visible side-by-side with tablet apps.
Microsoft doesn’t have this, Apple doesn’t, Google doesn’t.
It looks promising, it runs on COTS hardware and it’s FOSS. What’s not to like?
I suspect, when the whole plan comes together, that they will have a compelling desktop OS, a compelling phone OS and a compelling tablet OS, all working very well together but without any lock-in. That sounds good to me and far preferable to shelling out thousands on new kit to achieve the same on Apple’s platform. Because C21 Apple is all about selling you hardware — new, and regularly replaced, too — and then selling you digital content to consume on it.
Ubuntu isn’t. Ubuntu’s original mission was to bring Linux up to the levels of ease and polish of commercial OSes.
It’s done that.
Sadly, the world failed to beat a path to its door. It’s the leading Linux and it’s expanded the Linux market a little, but Apple beat it to market with a Unix that is easier, prettier and friendlier than Windows — and if you’re willing to pay for it, Apple makes nicer hardware too.
But now we’re hurtling into the post-desktop era. Apple is leading the way; Steve Jobs finally proved his point that he knew how to make a tablet that people wanted and Bill Gates didn’t. Gates’ company still doesn’t, even when it tries to embrace and extend the iPad type of device: millions of the original Surface tablets are destined for landfill like the Atari ET game and Apple Lisa. (N.B. *not* the totally different Surface Pro, but people use it as a lightweight laptop.)
But Apple isn’t trying to make its touch devices replace desktops and laptops — it wants to sell both.
Ubuntu doesn’t sell hardware at all. So it’s trying to drag proper all-FOSS Linux kicking and screaming into the twenty-twenties: touch-driven *and* by desk-bound hardware-I/O, equally happy on ARM or x86-64, very shiny but still FOSS underneath.
The other big Linux vendors don’t even understand what it’s trying to do. SUSE does Linux servers for Microsoft shops; Red Hat sells millions of support contracts for VMs in expensive private clouds. Both are happy doing what they’re doing.
Whereas Shuttleworth is spending his millions trying to bring FOSS to the masses.
OK, what Elon Musk is doing is much much cooler, but Shuttleworth’s efforts are not trivial.
They're a bit better in some ways. It's somewhat marginal now.OK. Position statement up front.Anyone who works in computers and only knows one platform is clueless. You need cross-platform knowledge and experience to actually be able to assess strengths, weaknesses, etc.Most people in IT this century only know Windows and have only known Windows. This means that the majority of the IT trade are, by definition, clueless. There is little real cross-platform experience any more, because so few platforms are left. Today, it's Windows NT or Unix, running on x86 or ARM. 2 families of OS, 2 families of processor. That is not diversity.So, only olde phartes, yeah like me, who remember the 1970s and 1980s when diversity in computing meant something, have any really useful insight. But the snag with asking olde phartes is we're jaded & curmudgeonly & hate everything.So, this being so...The Mac's OS design is better and cleaner, but that's only to the extent of saying New York City's design is better and cleaner than London's. Neither is good, but one is marginally more logical and systematic than the other.The desktop is much simpler and cleaner and prettier.App installation and removal is easier and doesn't involve running untrusted binaries from 3rd parties, which is such a hallmark of Windows that Windows-only types think it is normal and natural and do not see if for the howling screaming horror abomination that it actually is. Indeed, put Windows types in front of Linux and they try to download and run binaries and whinge when it doesn't work. See comment about cluelessness above.(One of the few places where Linux is genuinely ahead -- far ahead -- today is software installation and removal.)Mac apps are fewer in number but higher in quality.The Mac tradition of relative simplicity has been merged with the Unix philosophy of "no news is good news". Macs don't tell you when things work. They only warn you when things don't work. This is a huge conceptual difference from the VMS/Windows philosophy, and so, typically, this goes totally unnoticed by Windows types.Go from a Mac to Windows and what you see is that Windows is constantly nagging you. Update this. Update that. Ooh you've plugged a device in. Ooh, you removed it. Hey it's back but on a different port, I need a new driver. Oh the network's gone. No hang on it's back. Hey, where's the printer? You have a printer! Did you know you have an HP printer? Would you like to buy HP ink? Macs don't do this. Occasionally it coughs discreetly and asks if you know that something bad happened.PC users are used to it and filter it out.Also, PC OSes and apps are all licensed and copy-protected. Everything has to be verified and approved. Macs just trust you, mostly.Both are reliable, mostly. Both just work now, mostly. Both rarely fail, try to recover fairly gracefully and don't throw cryptic blue-screens at you. That difference is gone.But because of Windows' terrible design and the mistakes that the marketing lizards made the engineers put in, it's howlingly insecure, and vastly prone to malware. This is because it was implemented badly.Windows apologists -- see cluelessness -- think it's fine and it's just because it dominates the market. This is because they are clueless and don't know how things should be done. Ignore them. They are loud; some will whine about this. They are wrong but not bright enough to know it. Ignore them.You need antimalware on Windows. You don't on anything else. Antimalware makes computers slower. So, Windows is slower. Take a Windows PC, nuke it, put Linux on it and it feels a bit quicker.Only a bit 'cos Linux too is a vile mess of 1970s crap. If it still worked, you could put BeOS on it and discover, holy shit wow lookit that, this thing is really fsckin' fast and powerful, but no modern OS lets you feel it. It's under 5GB of layered legacy crap.(Another good example was RISC OS. Today, millions of people are playing with Raspberry Pis, a really crappy underpowered £25 tiny computer that runs Linux very poorly. Raspberry Pis have ARM processors. The ARM processor's original native OS, RISC OS, still exists. Put RISC OS on a Raspberry Pi and suddenly it's a very fast, powerful, responsive computer. Swap the memory card for Linux and it crawls like a one-legged dog again. This is the difference between an efficient OS and an inefficient one. The snag is that RISC OS is horribly obsolete now so it's not much use, but it does demonstrate the efficiency of 1980s OSes compared to 1960s/1970s ones with a few decades of crap layered on top.)
be sort of all right, if you don't expect much, are savvy, careful and smart, and really need some proprietary apps.
If you just want the Interwebs and a bit of fun, it's a waste of time and effort, but Windows people think that there's nothing else (see clueless) and so it survives.
Meanwhile, people are buying smartphones and Chromebooks which are good enough if you haven't drunk the cool-aid.
But really, they're all a bit shit, it's just that Windows is a bit shittier but 99% of computers run it and 99% of computer fettlers don't know anything else.
Once, before Windows NT, but after Unix killed the Real Computers, Unix was the only real game in town for serious workstation users.
Back then, a smart man wrote:
“I liken starting one’s computing career with Unix, say as an undergraduate, to being born in East Africa. It is intolerably hot, your body is covered with lice and flies, you are malnourished and you suffer from numerous curable diseases. But, as far as young East Africans can tell, this is simply the natural condition and they live within it. By the time they find out differently, it is too late. They already think that the writing of shell scripts is a natural act.” — Ken Pier, Xerox PARC
That was 30y ago. Now, Windows is like that. Unix is the same but you have air-conditioning and some shots and all the Big Macs you can eat.
It's a horrid vile shitty mess, but basically there's no choice any more. You just get to choose the flavour of shit you will roll in. Some stink slightly less.
I had a brief play with one on my last trip through Stansted Airport back to Czechia. I disliked the feel of the keyboard, then I realised how very fast & accurate it had been on the few test lines that I had typed.
As the only sensible-sized smartphone on the market today with an actual hardware keyboard, I'm very tempted. I'm also kinda fed up with Android.
With a little luck, my Note 2 might still have some resale value, too.
Unfortunately, all the reviews I can find are dreck like this:BlackBerry Passport review: Getting stuff done or getting in the way?
By Dan Seifert on September 24, 2014 10:00 am Email @dcseifert
It contains a lot of the typical bollocks that normally makes me denigrate smartphone reviews.
Whinge whinge it's too big whinge no Instagram whinge no Snapchat whinge no $shitty_proprietary_bullshit_toy_chat_ap
p whinge videos don't look nice whinge.
No archiving in Gmail is a slight snag, but unlike Dan, I understand folders and filters and they do 99% of my archiving for me, so I don't care that much.
Well I am not a hormonal teenager who wants to give or get cock-shots. I don't give a flying fuck about Snapchat, Instagram or any of that puerile drivel.
I don't watch videos on my phone, because it's a tool not a toy, but I type on it all the time
. I detest
virtual keyboards. I'm a middle-aged bloke with proper big man-sized hands; I can use a Galaxy Note 2 one-handed, no problem, and if one of these many little nappy-wearing pseudo-journos with the hands of a 12 year old girl can't grip it, that's a good thing
because I can't use tiny crappy toys like normal iPhones. The 6+ is the first ever iPhone that is remotely big enough to be usable to me, and it's too thin and its battery too weedy. I want an inch-thick phone with circa 5 amp-hours in it, like I had 6 or 7y ago, please, not some svelte buttonless hairdressers' phone.
So, not very helpful review, directly, inasmuch as the man-child who wrote it clearly wants something I'd perceive as a teen's plaything. I am
the kind of boring old pharte with a job to do that he tries & utterly fails to imagine being.
But they're all like that, the Passport reviews. They're by bloody children who regard Flappy Bird as a mission-critical app.
But, OTOH, while Mr Still-Spattered-With-Spit-From-School there can't swap images of his small, soft and as-yet hairless genitals with his other playmates on it, he does manage to tell me that it's big, boring, solid and wide. These are good things
My Note 2 is if anything too small. It doesn't reach from ear to mouth, as a proper phone should, it has no physical buttons, and at 2y old its battery lasts about 4-6h.
(So does its 1y old replacement battery.) But it's too wide, because it's made for watching videos on, and it wastes space on a pointless stylus when really I want it 1cm thicker with a QWERTY keyboard and in an ideal world 2 SIM slots and 2 batteries.
Really, I want a big bricklike Nokia Communicator (or at a push an HTC Universal; mine had an inch-thick 4800 mAh battery, weighed 450g & was the last smartphone I owned with a good
battery life)... but with a modern OS.
Sadly, though, all the phone companies are too busy wanking over leaked pictures of Apple products and making shitty compromised me-too toys to produce something for aging adults with dimming eyesight and big hands.
I was just wondering if the last bastion of vaguely sensible boring phones had made something worth buying.
I have been meaning to try Arch Linux
As a former RPM user, once I finally made the switch to
Ubuntu, more or less exactly 10y ago, well, since then, I have become so wedded to
APT that I hesitate with non-APT distros.
My spare system on this machine is Crunchbang, which I like a lot, but is a bit too Spartan in its simplicity for me. Crunchbang is based on the stable version of Debian, which gives it one big advantage on my 2007-era built-for-Windows-Vista hardware: it uses a version of X.org so old that the ATI fglrx drivers for my Radeon HD 3470 GPU still work, which they haven't done on Ubuntu for 2 years now.
But there was a spare partition or 2 waiting. I tried
Elementary -- very pretty, but the Mac OS X-ness is just skin-deep; it's GNOME 3, very simplified. No ta. Deepin is too slow and doesn't really offer anything I want -- again, it's a modification of GNOME 3, albeit an interesting one. Same goes for Zorin-OS. I've tried
Bodhi before -- it's interesting, but not really pretty to
my eyes. (Its Enlightenment desktop is all about eye-candy; as a desktop, it's just another Windows Explorer rip-off. If it shipped with a theme that made it look like one of those shiny floaty spinny movie-computer UIs, I might go for it, but it doesn't, it's all lairy glare that only a teenage metalhead could love.) Fedora won't even install; my partitioning is too complex for its installer to
understand. SUSE is a bit bloaty for my tastes, and I don't like KDE (or GNOME 3), which also rules out PCLinuxOS and Deepin.
was the next logical candidate...
I've been a bit sheepish since an Imaginary Internet Friend, Ric Moore, tried it with considerable success a month or two ago. (As I write, he's in hospital having a foot amputated. I've been thinking of him tonight & I hope he's doing well.)
So I have finally done it. Downloaded it, burned it to
a CD -- yes, it's that small -- installed it on one of my spare partitions and I am in business.
After a bit of effort and Googling, I found a simple walkthrough, used it, got installed -- and then discovered that Muktware only tells you about KDE, and assumes you'll use that and nothing else. I don't care for KDE in its modern versions, so I went with Xfce.
Getting a DM working was non-trivial but now I have LXDM -- the 3rd I tried
-- and it works. I have an XFCE4 desktop with the "goodies" extras, Firefox, a working Internet connection via Ethernet, and not much else.
It does feel very quick, though, I must give it that. Very
snappy. I guess now begins the process of hunting down all the other apps that I use until I've replicated all my basic toolset.
The install was a bit fiddly, much more manual than anything I've done since the mid-1990s, but actually, it all went on very smoothly, considering that it's a lot of hand-entered commands which actually do not seem to depend much on your particular config.
[Recycled (part of) a mailing list post: another crack at trying to explain what was significant about LispMs.]
One of the much-ignored differences between different computer architectures is the machine language, the Instruction Set Architecture (ISA). It's a key difference. And the reason it doesn't get much attention is that these days, there's really only one type left: the C machine.
There used to be quite a diversity -- there were various widely-divergent CISC architectures, multiple RISC ones, Harvard
versus von Neumann designs, stack machines
versus register machines, and so on.
Most of that has gone now -- either completely disappeared, or shrunk into very specific niches.( Read more...Collapse )
Long time, no post. This is because since April, I have started a new job where I actually get paid to write technical stuff for a living.
(Hint - I'm going to have to change that usericon...)
Anyway, this subject came up in conversation with my colleague Pavel recently. In my department, there are some Vi[m] advocates, at least one Emacs user in the wild (approach with caution), and when I said I used Gedit from choice
, I got pitying looks. :¬)
Which gave me a chance to have my usual rant about the deep and abiding nastiness of both Vi and Emacs, which did at least provide some amusement. It also led Pavel to ask, quite reasonably, what I did want from a console/shell text editor that wasn't provided by, say, Joe, Nano or Pico.
I said CUA and then had to explain what CUA was, and pointed at SETedit, which I've linked to before. Sadly, it hasn't been updated in a while. Packages are only for old versions of popular distros.
Firstly, there's the rather fun Text Editors Wiki, which is not as comprehensive as it might be but has a lot of interesting reading.http://texteditors.org/cgi-bin/wiki.pl
First, he pointed me at XWPE. It certainly looks the part, but sadly the project seems to have died. I did get it running on Fedora 20 by installing some extra libraries and symlinking them to names XWPE wanted, but it crashes very readily.
http://fte.sourceforge.net/More recently, I've also discovered Tilde. It is currently maintained and has recent packages available. It looks a bit richer than eFTE, but sadly, the Alt key doesn't work in a window. Clearly this is a known issue as there's a workaround using Esc instead, but it makes it 2 keystrokes rather than one with a modifier.
http://os.ghalkes.nl/tilde/I remain surprised that these things are obscure & little-known. I'd have thought that given how many people are moving from other OSes to Linux, a lot more MICROS~1 émigrés would have wanted such tools.
I am already sick and tired of listening to clueless noobs who think they're techies saying "XP is fine, stop worrying" or "I don't do Linux, it's too different" or "I tried it in 2002 and it was rubbish".
Well it's longer since Ubuntu came out (2004) than the gap from Windows for Workgroups 3.11 to Windows XP. Remember the extent of those changes? Well Linux changes a lot faster.
And so what if it's not the same? It's not like changing from a car to a motorbike. It's not that different any more.
To a techie who looks under the hood, who does their own maintenance, sure, it's going from petrol car to electric bike or something. Very little in common.
To someone who uses a desktop, browses the web, plays some simple Flash games or Solitaire etc., occasionally opens a PDF and prints it, or opens an MS Office doc, completes a form and sends it back, stuff like that, then an appropriately-chosen Linux is more like WinXP than Win8 is by far.
But there is galloping fear of the alien in IT. Probably, I suspect, because there are millions of people working in IT who know nothing at all except MS Windows. Everything else is foreign to them, alien and terrifying, and they instantly react like a pod-person in the 1970s Invasion of the Body Snatchers.
And you know what? It's appropriate, because you're all fucking pod people. Stamped out, copies, clones, with no originality and no imagination. You're neophobic.
Anyone who actually knows about computers - real tech people - can handle any OS, any machine. I've troubleshot and fixed problems with machines I have never seen or heard of before; I've sorted out stuff on AS/400 and IBM System/360 mainframes, I've got a DEC PDP-11 talking and doing file exchange with a classic Mac running System 7, and before I walked in, I had never even seen a PDP-11 in my life before.
Software is an office supply, like paperclips. Today it all does much the same, in much the same way.
Imagine the contempt you'd feel for someone who bleated and whinged and complained that they were given a different brand of stapler, or they had to change filing cabinets to one where the keyhole's on the other side. You'd sneer at someone who demanded a training course to help them adjust.
Anyone who only knows one platform, one OS, is not a techie at all, not of any type. If you can't drive half a dozen kinds of computers then you can't drive.
Any competent biker could switch from a 125 trailie to a Gold Wing to a superbike and not kill themselves when they twisted the throttle. They'd go with respect and care and caution, not bleat like an infant because one of the buttons on the handlebars had moved and was a different colour.
So bloody well grow up.
Linux is an answer to a problem. If you have an old XP computer, no it is not safe to use it any more, and yes, you should replace it. But if you get a new one with Win8, it will be very very different indeed. They don't even have a BIOS any more, let alone a bloody Start menu.
And if you don't have the money for a new one, well, an old XP computer won't run Windows 7 properly, no.
But there's a perfectly good alternative that is faster, simpler, safer, more secure, more reliable and it doesn't even cost anything. It'll run on anything XP runs on, works great and all you have to do is get your hands oily. Use Google. Don't think "I know this." You don't. No, not all computers install software by downloading a binary and running it - in fact, that's a fucking stupid design, which spreads malware. Not all computers use a website for updates - that's a fucking stupid design, too.
So grow a pair. Stop whinging. Google "how to install skype ubuntu" rather than downloading and fucking about and breaking it. Download "how to enable GeForce 240 ubuntu 12.04" before you go wasting time. Google "transfer IE bookmarks Firefox" or "libreoffice excel compatibility" or whatever.
Don't assume you know. Assume you don't. You have the entire world's information resource at your fingertips. Use it. Ask the Internet. Ask bloody Ixion.
But stop fucking whinging that "it doesn't run my copy of Anus Invaders 6" or "my crappy plastic £30 printer from PC World doesn't work" and buy a better one. It's cheaper than a new ink cartridge anyway.
Learn. Life is learning. Life is growth. Stop acting like a corpse and live.
Frankly, coming from a background in 1980s and 1990s OSes, I think modern ones are appalling shite. They're huge, baggy, flabby sacks of crap that drag themselves around leaving a trail of slime and viscera - but like some blasphemous shoggoth, they have organs to spare, and the computers they run on are so
powerful and have so
much storage that the fact that these disgusting shambling zombie Frankenstein's-monster things, stitched together from bits of the dead, dropping eyeballs and fingers, actually work for weeks on end.
On the server, no problem, run hundreds of instances of them, so when they implode, spawn another.
It's crap. It's all terrible, blatantly obvious utter crap, but there's almost nobody left who remembers any other way. I barely do, from old accounts, & I'm near 50.
We have layers of sticking-plaster and bandages over kernels that are hugely-polished turds, moulded into elegant shapes. These are braindead but have modules for every conceivable function and so can run on almost anything and do almost anything, so long as you don't mind throwing gigabytes and gigahertz at the problem.
And those shiny turds are written in braindead crap languages, designed for semi-competent poseurs to show off their manliness by juggling chainsaws: pointless Byzantine wank like pointer arithmetic, missing basic types for strings, array bounds-checking, and operator overloading. Any language that even allows the possibility of a buffer or stack overflow is hopelessly broken and should be instantly discarded. The mere idea of a portable assembly language is a vestige of days when RAM was rationed and programmers needed to twiddle bits directly; it should have been history before the first machine with more than a megabyte of RAM per user was sold.
Computers should be bicycles for the mind. They let us take our existing mental tools and provide leverage, mechanical advantage, to let us do more.
We work in patterns, in sets, in rich symbols; it is how we think and how we communicate. That, then, should be the native language to which our computers aim: the logic of entities and sets of entities, that is, atoms and lists, not allocated blocks of machine storage - that is an implementation detail, it should be out of sight, and if it's visible, then your design is faulty
. If you routinely need
to access things, then your design is not even wrong
By the late '50s we had a low-level programming language that could handle this. It's unreadable, but it was only meant to be the low-level; we just never got the higher level wrapper to make it readable to mortals. The gods themselves can work in it; to lesser beings, it's all parens
Now, we have a rich choice
of higher-level wrappers
to make it all nice
and easy and pretty
. Really very pretty
And later, people built machines specifically to run that language, whose processors understood
But they lost out. CPUs were expensive, memory was expensive, so instead, OSes grew simpler; Unix replaced Multics, and CPUs grew simpler too, to just do what these simple OSes written in simple languages did. Result, these simple, stripped-down machines and OSes were way more cost-effective, and they won. The complex machines died out.
Then the simpler machines - which were still quite big and expensive - were stripped down even more, to make really cheap, rudimentary 4-bit CPUs for calculators
, ones that fitted on one chip.
They sold like hotcakes, and were developed and refined, from 4-bit to 8-bit
, from primitive 8-bit to better 8-bit
, with its own de-facto standard OS which was a dramatically simpler version
of a simple, obsolete OS for 16-bit minicomputers.
And that chip begat a clunky segmented 8/16-bit one
, and that a clunky segmented 16-bit
one, and that a bizarre half-crippled
32-bit one that could emulate lots of the 8/16-bit one in hardware
FFS. And that redefined the computer industry and it was nearly two decades
until we got something slightly better
, a somewhat-improved version of the same old same old.
And that's where we are now. The world runs on huge, vastly complex scaled-up go-faster versions of a simplified-to-the-maximum-extent-possibl
e calculator chip. These chips grew out of a project to scale-down simple, dumb, brain-dead chips built to be cheap-but-quick because the proper ones, that people actually liked
, were too expensive 40 years ago. Of course, now, the descendants of those simplified chips are vastly more complex than the big expensive ones their ancestors killed off.
And what do we run on them? Two OSes. One a descendant of a quick-n-dirty lab skunkworks project to make an old machine useful for games, still today written in portable assembler with richer portable-assembler things written in the lower-level one running on top of it. And a descendant of a copy of a copy of a primitive '60s mini OS which has been extensively rewritten in order to imitate the skunkworks thing.
But these turds have been polished so brightly, moulded into such pretty shapes, that they've utterly dominated the world since my childhood. It's still all made from shit but it's been refined so much that it looks, smells and tastes quite nice now
We still are covered in shit and flies - "binaries", "compilers", "linkers", "IDEs", "interpreters", "disk" versus "RAM", "partitions" and "filesystems", all this technical cruft that better systems banished before the first Mac was made, before the 80286 hit the market.
But as the preface to the Unix-Hater's Handbook says:
``I liken starting ones computing career with UNIX, say as an undergraduate, to being born in East Africa. It is intolerably hot, your body is covered with lice and flies, you are malnourished and you suffer from numerous curable diseases. BUT, as far as young East Africans can tell, this is simply the natural condition and they live within it. By the time they find out differently, it is too late. They already think that the writing of shell scripts is a natural act.''

any more. And when you try to point out that there was
once something better, that there are
other ways, that it doesn't need to be like this... people just ridicule you.
And no, in case it's not clear, I am not a Lisp zealot. I find it unreadable and cannot write "hello world" in it. I also don't want 1980s Lisp Machines back - they were designed for Lisp programmers, and I'm not one of them.
I want rich modern programming languages, as easy to read as Python, as expressive as Lisp, with deep rich integration into the GUI - not some bolt-on extra like a tool to draw forms and link them to bits of code in 1970s languages. There's no implicit reason that why the same language shouldn't be usable by a non-specialist programmer writing simple imperative code, and also by a master wielding complex class frameworks like a knight with a lightsabre. It's all code to the computer: you should be able to choose your preferred viewing level, low-level homoiconicity or familiar Algol-like structures. There shouldn't be difference between interpreted languages and compiled - it's all the same to the machine. JIT and so on solved this years ago. There's no need for binaries at all - look at Java, look at Taos and Intent Elate
, look at Inferno
's Limbo and Dis. Hell, look at Forth over 30 years ago: try out a block of code in the interpreter; once it works, name it and bosh, it's compiled and cached.
Let's assume it's all FOSS. No need for licences mandating source distribution: the end-product is all source
. You run the source directly, like a BASIC listing for a ZX Spectrum in 1983, but at modern speeds. If you aren't OK with that, you don't like distributing your code, fine, go use a proprietary OS and we wish you well. Hope it still works on their next version, eh?
It could be better than we have. It should
be better than we have. Think the Semantic Web all the way down: your chip knows what a function is, what a variable is, what a string or array is - there's no level transition where suddenly it's all bytes. There doesn't need to be.
And this stuff isn't just for programmers. I'm not a programmer. Your computer should know that a street address is an address, and with a single command you can look up anyone's address that is in any document on your machine - no need to maintain a separate address-book app. It should understand names and dates and amounts of money; there were apps that could do this in the 1980s. That we still need separate "word processors" and "spreadsheets" and "databases" today is a sick joke.
I have clients who keep all their letters in one huge document, one per page or set of pages per correspondant... and there's nothing wrong with that
. We shouldn't be forced to use abstractions like files and documents and folders if we don't want to.
I have seen many clients who don't understand what a window is, what a scrollbar does; these abstractions are too complex for them, even for college professors after decades of use of GUIs. That's why iPads are doing so well. You reach out and you pull with a fingertip.
And that's fine, too. The ancestor of the iPad was the Newton, but the Newton that got launched was a crippled little thing; the original plan was a pocket Lisp Machine, with everything in Dylan all the way down to the kernel.
And the ancestor of the Macintosh was Jef Raskin's "information appliance", with a single global view of one big document. Some bits local, some remote; some computed, some entered; some dynamic, some static; with the underlying tools modular and extensible. No files, no programs, just commands to calculate this bit, reformat that bit, print that bit there and send this chunk to Alice and Charlie but not Bob who gets that other chunk.
Sounds weird and silly, but it was, as he said, humane; people worked for millennia on sheets of paper before we got all this nonsense of icons, files, folders, apps, saving, copying and pasting. The ultimate discrete computer is a piece of smart paper that understands what you're trying to do.
And whereas we might be able to get there building on bytes in portable assembler, it will be an awful lot harder, tens to hundreds of times as much work and the result won't be very reliable.
Apparently, it's the ultimate Linux, and with his tweaks to the current development kernel and a custom scheduler, it's insanely responsive, and if you haven't tried it, you're not a Linux god.
So I said...
Um. Good for you. I am pleased you've found a system you find nicely responsive.
Me, I just want something simple, low-maintenance and reliable, with a
good polished rich UI, that does what I need. The less work I have to
do to achieve this, the better the OS is, for me.
Yours sounds very high-maintenance indeed and I'm not remotely
interested in going to all that work.
I don't consider myself a Linux god. I am reasonably clueful. I've
been using Ubuntu since it came out in 2004, SuSE for a couple of
years before that, Caldera for a couple of years before that. That
followed a good few years on NT 3.51 and NT 4, which followed Windows
95. I switched to Windows 95 from OS/2 - I was a keen OS/2 user from
2.0 to 2.1 to 3.0. It really was the best 32-bit OS for PCs back then.
Before that, at work, I built, ran and supported servers running SCO
Unix and before that SCO Xenix. My Unix experience goes back to about
1988, which is when I switched over from the VAX/VMS I used at
I have also used IBM AIX and SUN SunOS and Solaris, but not much.
Plus Novell Netware - I was a bit of a guru on Netware 2 and 3 but
wasn't so impressed with Netware 4 and have barely used 5. I wrote a
masterclass on building a small-business server with Red Hat 6 for PC
Pro magazine in the late 1990s. I've also reviewed about 20 or 30
Linux distros over the years, so I feel I know the Linux landscape
I'm also very interested in alternative (non-Unix) OSes, especially
for the PC. BeOS is my personal all-time favourite.
Off PC hardware, I'm also pretty good on Mac OS X and classic Mac OS,
before thzat Acorn RISC OS and Psion EPOC and its successor Symbian,
and have some knowledge of AmigaOS, Atari GEM (I was peripherally
involved in the GPL FOSS FreeGEM project to revive PC GEM; my name's
in the credits of FreeDOS, to my startlement.)
I was definitely an MS-DOS guru back in the late 1980s/early 1990s and
supported all the major networking systems - 3Com 3+Share, 3+Open, DEC
Pathworks, AppleShare, Sage MainLAN, Personal Netware, Netware Lite,
NT Server from the very first version, etc.
So I guess you could say that my knowledge is broad but in places
shallow, rather than very deep in any one area, such as Linux. :-)
But I feel really sorry for you if you think that /any/ Linux system
is genuinely fast and responsive. It's not. It's a huge lumbering
sloth of an OS. You really need to try BeOS, or failing that Haiku, if
you want to experience what a fast responsive OS on PC hardware feels
Sadly, there just weren't the apps for it, and no VMs in those days.
And for something vastly more responsive than Haiku, try Acorn's RISC
OS. It's the original OS for the ARM chip that these days struggles to
run bloated leviathans like Apple iOS and Android. RISC OS is the
single most responsive system I've ever used, because the entire core
OS - kernel, GUI, main accessory apps - fits into about 6MB of Flash
No, that's not a typo. Six megabytes. Complete Internet-capable
multitasking GUI OS with network clients etc.
It runs on the Raspberry Pi and RISC OS itself is now shared-source
freeware so you can download it from Risc OS Open Ltd. for nothing and
run it on a £25 computer - on which it performs very very well, many
tens of times faster than a lightweight cut-down Linux such as
So, no, not a Linux god, but, you know, not a n00b either.
Try some of these OSes. Prepare to be surprised. You might enjoy the experience.
Most of them have nice friendly GUI text editors, too, way friendlier
than Vi /or/ Emacs. ;-D

No, the DOS limits were /much/ earlier and older.
From old old memory:
MS-DOS 1.x didn't support hard disks.
MS-DOS 2.x did, but just one, of up to 10MB.
MS-DOS 3.0 supported a single hard disk partition (per drive) of up to 32MB.
MS-DOS 3.2 supported two partitions per drive, so 2 x 32MB.
MS-DOS 3.3 supported one primary and an extended partition containing as many 32MB "logical drives" as you wanted. (I built an MS-DOS fileserver with a 330MB hard disk once - it had drive letters C:, D:, E:, F:, G:, H:, I:, J:, K: and a leftover 11MB L: drive. Messy as hell but all you could do without 3rd party "disk extenders" such as Golden Bow's one. The server OS was 3Com 3+Share if anyone remembers that.)
Lots of vendors implemented hacks and extensions to allow bigger disks, but they were all mutually incompatible and many failed to work with some 3rd party software. Of course, anything that directly accessed disk data structures, like a defragger or a disk-repair tool such as Norton Utilities was 100% guaranteed to catastrophically corrupt any such extended disk setup.
The one that caught on was Compaq DOS 3.31. It used an extension of FAT16 that allowed bigger clusters - still just 65,535 of them, but multiple 512 byte sectors per cluster, permitting bigger partitions. The max cluster size was 16KiB so the max disk size was 65535*16KiB = 2GiB.
This is the one that IBM adopted into MS-DOS 4 and it became the standard. However, disks over 512MB used inefficient 8KiB clusters - i.e. files were allocated with a granularity of 8KiB and even a 1 byte file took 8KiB. An 8.0001KiB file would take 16KiB.
This became disastrous over 1GiB where the granularity was 16KiB. Roughly 20-30% of disk space would be wasted because of this granularity as inaccessible "slack space".
This was only fixed in Windows 95 OSR2 with FAT32, which permitted huge disks - up to 2TiB - with much finer granularity.
But all of DOS 4, 5 and 6.x permitted disk partitions of up to 2GiB.
