Obsolete Technical Skills
Ponca City, We Love You writes "Robert Scoble had an interesting post on his blog a few days ago on obsolete technical skills — 'things we used to know that no longer are very useful to us.' Scoble's initial list included dialing a rotary phone, using carbon paper to make copies, and changing the gas mixture on your car's carburetor. The list has now been expanded into a wiki with a much larger list of these obsolete skills that includes resolving IRQ conflicts on a mother board, assembly language programming, and stacking a quarter on an arcade game to indicate you have next. We're invited to contribute more."
Systems programmers worth their salt can at least read assembler output. It's a valuable skill when debugging kernel errors.
My Dad started out working on valve amplifiers in the 1950's. Now that he has retired I want to start a business with him fixing valve amplifiers.

If you have to write bootloaders and a very small number of other programs or routines. For most purposes, yes, it's rather counterproductive.
"Your mouse has been moved. Windows 95 must be restarted for the change to take effect."
Fortran isn't obsolete. It's still popular in particle physics. Also, "buying an HD-DVD" is on the list. Not that that was ever a "skill." This list is just begging to be filled with joke entries like that.
This is a list that states what the author doesn't do any more, but it's quite arrogant to assume he speaks for everyone.
I've been waiting for this all the time... The knowledge of assembly language should have been obsoleted a long time ago, since, naturally, all the compiler programmers today just...wait...there's something fishy here...

Navigating by compass is obsolete? That's like saying that keeping candles in your house in case of extended blackouts is obsolete.
Some things on that list are either silly or shortsighted.
I'm neither a console programmer nor a demoscener, but isn't assembly very much alive and kicking in these two fields?
If you haven't made a developer cry, you've wasted a day.

Next he'll be saying we've lost the technical skill of picking up the phone handset because of speaker phones and mobile phones.
Anyway , here in the UK new and refurbished rotary phones are a niche fashion item. You can pick them up in a number of places for a reasonable amount.
Without assembly knowledge we'd have uncrackable IP "protection" schemes.
Churn butter is on the list. I guess it just comes that way out of the cow now. Science is amazing.

I design embedded systems for a living, and this obsolete assembly language skill is what distinguishes my designs from those other companies. True, it takes me a little longer to get the code done, but it runs faster, has more features, and fits into a much smaller memory space than what I could do with C, or anything else. (Not to mention the fact that all the bugs in my code are all mine and none were introduced by a compiler.) I feel like it's to my advantage that assembly has faded from most designer's skill set. I won't deny that this skill is on the endangered species list, but to group it with the skill needed to dial a rotary phone made me speak up. It may be rare but it certainly isn't useless.
If I didn't have absolutely NOTHING to do, I wouldn't be here.
Everything which is written in Java uses C.
Everything which is written in C uses Assembler.
Everything which is written in Assembler uses machine code.

I have been reading Alan Greenspan's autobiography and he consistently mentions the concept of "creative destruction," which perfectly describes the duality of the capitalist society we live in (even all of you supposed socialists in Europe). It describes both the benefit and burden of the market economy. The benefit of having (generally) free markets allocate resources in society is the innovation they brings (i.e., progress), but a cost of that progress is the obsolescence of things which are now, for lack of a better phrase, useless because of it.
I've noticed that we on Slashdot seem to struggle with this concept daily, be it the loss of jobs to outsourcing, development and adoption of new technology, reform of IP laws, the slow death of the MPAA/RIAA, and even the subject of this article (which is the perfect example). It is probably a little off-topic, but I think this common thread should in these subjects should be pointed out, because all of our discussions seem to hinge on this critical question: Is the creation worth the destruction?

I'd love to see some speculation on what skills you'd expect to be obsoleted by 2029.
There are probably many times more people capable of programming in assembly language today than in the 70s. Kernel developpers, compiler developers (obviously!), CPU designers, embedded systems developpers and so on.
On the other hand, there are many times less people capable of making horse buggies than in the XIXth century; that's obsolete.
Assembly language is FAR from obsolete. Embedded hardware outships PCs by probably 100 to 1, and much of that is programmed using assembly language (especially if you want to get the most out of the tiny hardware). I have modern microcontrollers in my parts box with 64 *bytes* of RAM and 1kbyte of flash (Atmel ATtiny13) - while you can write a C program for this device, you can get much more out of it with asm, and it doesn't really take any longer to write (AVR asm is one of the nicer 8 bit ISAs). Portability is rarely an issue for devices like this, since even the C code won't be portable to other microcontroller architectures.
...oh, and I have a rotary phone, too. It was first installed in my grandparents home in 1969 when the house was built. It's just the plain GPO phone of the time, but it's a little reminder of them each time I phone someone.
Every serious programmer should have some experience of assembly language so they can grok what's really going on. Nothing tells you why buffer overruns are so bad than watching a program written in asm run over its own stack obliterating the return address. It doesn't need to be a fancy 32 bit or 64 bit desktop chip, an 8 bit ISA or one of the classics such as the Motorola 68K is enough to understand the principles of what happens at the chip level. If you want to see what happens when programmers simply don't grok the hardware, just check out The Daily WTF.

As someone who uses many languages I can tell you this: All imperative languages can be learned in very reasonable time if you know your C. Everything is derived from C today, from PHP to Perl to Java. Why? Well, maybe because the guys who wrote those languages come from C.
In a nutshell, it doesn't matter what language you use, which language is the next big thing, or what language becomes obsolete tomorrow. You will probably not know all those fancy functions that do what you used to do by hand, but what matters is whether you know the math behind the code. I've seen so many people claiming to know Java, C# and whatnot, just to give me that incredibly blank stare when I ask them for hash tables. Yes, they know every function, every class in Java by heart, but they have no knowledge of what they should actually DO with it.
Now, it might not be a "necessity" tomorrow when there is a function that does it for you. But it is VERY easy to learn about a function (hell, look it up, it ain't like there's no online help file for it) while it is not so trivial to understand what it actually DOES.
So it does not matter what language will arise or what language becomes obsolete. What matters is that you know the theory behind the structures you're supposed to use. When you know that, you can understand what the functions and classes do. When you understand that, you can more efficiently and sensibly fill them. When you do that, your program will work with fewer bugs and fewer "why the fu.. doesn't that work now, it did last time" moments.
Don't learn languages. Learn theory!

I'm glad some people think that Assembly programming is obsolete. That way, it's much easier for me to get one of the many jobs which requires assembly programming.

Emacs! No, wait, VI! Functional programming! Python! Java! Perl! Ruby! Oh man, I'm like a troll kid in a candy store!
Programming in VB, PHP or Ruby does not make you stupid per se. Capable programmers that understand what goes on under the hood actually use these languages.
Programming a website in assembly, on the other hand, would be pretty thickheaded.
My point is that a knowledge of assembly is indeed very usefull for any programmer. I only disagree with your gratitious bashing of script languages and their users.

My father and I worked on old Saabs, way back when they were cool. He was a self-taught engineer: he had a Civil Service equivalency, no college degree, and worked as an engineer for the FAA.
He was the master at converting 3-cylinder Saab 96 (and 95) models to the newer V4 engine. He had it down to a science, and cars we converted ran all over the country.
A few of the more mundane skills I learned back then:
--Setting the dwell angle by adjusting the ignition points, then rotating the distributor to set the ignition timing.
--Disconnecting the ringer on Western Electric rotary-dial phones, so Ma Bell couldn't detect how many extentions you had (illegally) connected to your line.
--Dialing only the last 5 digits of a 7-digit phone number: within the same exchange, the mechanical switches at the local Bell office would make the connection.
--Scraping conducting material off the rotary dial in the cable box to enable HBO and Showtime.
I've been thinking about retiring - I'm 34 years old. I think I'd be happier if I'd jump off the bandwagon and started doing something totally different. Something that would not require me to study all the time and be stressed all the time.
I grew up with home computers. I learned BASIC when I was 11. That is obsolete skill now. Then I got my first PC in 1988 and learned DOS. That's obsolete. Then I learned Borland's Turbo Pascal. That's obsolete. Then I learned Microsoft C programming and started programming Windows 3.1 applications that used Windows menus etc. That's obsolete. I learned Gopher and Telnet in the 80s. That's obsolete. I learned Pine. That's obsolete. I learned to tweak Windows 95 registry. That's obsolete. I learned BEA Tuxedo at work. That's obsolete. Looking at it now - I've wasted countless of hours to something that is totally obsolete now! Had I invested that time into improving myself - learning who I am, how I behave, how to enjoy this life - I would be much happier now I guess.

There are many many useful and relevant skills on there.
Oh this is cool! I could go on and on and on. While it's true some of these skills are still necessary for a few "elite" programmers or engineers, most of these skills are no longer used by the average user. To wit:
- what to do with a Commodore 64 when its cursor is blinking at you
-----(everyone I know in my circle of friends would go "duh")
-----(they have no clue how to navigate without icons or explorer)
- how to write a simple basic program for your C=64:
----- 10 print "hello"
----- 20 goto 10
----- RUN
- LOAD "$" to get directory off my cassette drive (yes we used cassettes)
- LOAD "*",8,1 to autoload & start most floppy disks
- how to crate 16-color pictures that look good
- how to program the SID to make music
- dir df0: to get a directory on a Commodore Amiga 500/2000
- the difference between Chip and Fast RAM
- why it's a bad idea to multitask 2 programs off the same floppy
-----(because the floppy will knock itself silly trying to read two tracks at the same time)
- ATDP 5601750 to dial on a rotary/pulse phone (ATDT for touchtone)
- +++ to get your modem's attention so you can issue commands like:
- ATH to hang up
- how to create pretty pictures using ANSI
- what is Zmodem, and why it's better to download files with Z rather than Xmodem
- how long will it take to download a 3.5 inch floppy over 2.4k modem
-----(long enough to eat supper and take a shower)
-----(or watch the latest episode of Star Trek The Next Generation)
- how many hours you can squeeze on a T-180 VHS tape (9)
- how many episodes of Quantum Leap if you remove the commercials (12)
- how to repair your copy of Star Wars after the tape tears in half (scotchtape)
Most of the things I just listed were items known by "everyone" back in the 1980s. If you wanted to use a computer, you had to know the various commands and understand how/why things work.
Today people don't need to know command-line text.
They can just point-and-click; it's become easy.
And a lot of the things we used to need to know?
It's essentially automatic now.

HD-DVD is obsolete. I feel sorry for those poor bastards that bought the new Beta. I never had a Beta Player myself, my mom opted for the VHS based on my uncles' advice. Any comments from anyone with prior experience in owning and operating an obsolete device that feels as though it just wont let go? In this day and age with HD-DVD I wonder how long it will take to completely disappear? We're either going to have bargain basement prices on HD hard and soft ware or they'll skyrocket in hopes of being a collectors item.

There are hundreds of obsolete skills. But there is one that NEVER goes out of fashion, never gets obsoleted, never stops coming in handy... the ability to learn quickly, and to remember what you learn. Seriously. I make a point of putting it on my CV (resume for you Americans). Learning quickly means you can adapt to ANY environment quickly. Remembering what you've learned means you can draw parallels and keep "generic" knowledge going. Bung me in front of a particular UNIX server and I might not have any idea how to do much but login. Give me ten minutes to acclimatise and I can be doing ANYTHING on it. TCP/IP is TCP/IP... the places where you change the settings may differ but knowledge of protocols, routing, etc. is the same whether it's a Commodore 64 on the web or a network of virtualised Vista PC's.
:-) The next was a full Windows 98 network with custom management software and an NT server. The next was a 2000 Server and XP network with custom management software. The next was plain 2000 + XP with Active Directory. The next was similar but with some other custom management software bodged to perform some of the more tedious tasks. The next was Server 2003 + XP + Vista. And so on. The last one I had was another "design me a network from scratch" for a school, and so they got Server 2003, XP and Linux for some tasks (it was just easier, made more sense and cheaper).
I don't have MCSE, CCNA or anything else because the sheer fact is that by the time you've passed the course and been using it for a year, its content is out of date. Not all of it, but quite a bit of it. Especially on those courses designed for particular bits of software. And they are nothing but memory tests. That's not learning.
I've done assembly, I've done BASIC and everything in between. My University tried to teach me Java until I stopped attending the lectures for that part and was instead "hired out" to other students as the person to ask about the Java coursework. I'd only ever dabbled in it but having programmed in a lot of other languages it was no more than a curiousity to flick through a Java book and pick up the syntax. I did the coursework myself at home, taught many others to pass the course, and passed myself (good grades for that course) with barely a sweat. I'd dabbled in Java before but it was merely a matter of flicking through a half-decent book on the subject, applying everything else you already know and making sure you have a list of function-method-procedure (call them whatever you like, OO is just a shortcut that saves you typing so much functional-programming code) name changes handy. KMP search algorithms are the same in any language, it's just a matter of learning or merely memorising (which is NOT learning) the differences between languages.
Similarly, my primary job is being hired by schools to manage their networks. First one was 98-standalones with Ethernet cables basically used for display.
Formal training in any of the above OS, network management, network management software or application software? Zilch. Number of networks exploded? Zilch. Number of networks more productive once I had finished with them? 100%. Number of schools chasing me for further employment to work on their next big network, next OS, next suite of applications? I lose count. And these are critical networks - they run everything from the canteen to the staff wages to the legally required paperwork to the student desktops to the fire and security systems. You have no idea how crippled a school is nowadays if its servers go down... lessons stop, systems go haywire and the students get sent home. And they literally fight over getting an imbecile like me in to manage their systems, or even just clean them up so that they can employ a "normal" technician next year.
If you can learn, you can run any OS, of any age, at any time, in any combination without a problem. If you can't then you're stuck memorising "Windows Vista for Dummies" until the next OS comes out a
That's because HR people interview for jobs. This is changing, at least here, where the recruitment of key personnel is being outsourced to recruiting companies who DO know what to look for in a good applicant. Mostly because they usually have terms like "applicant must stay 6 months before we see any money" in their contracts.

Very interesting. For me, sex was a non-skill until I got married.
Bad career move, huh?
I haven't read the article or the Wiki (I'm not new to Slashdot, after all) but I figured this is as good a place as any to post this insane dribbel from my head.
Back when I was a kid, I grew up in a modest town of about 50,000 people. Too big to be a small town, not big enough to get on most maps. Our phone book was about one inch thick. Small towns had phone books that were essentially glorified pamphlets, about 1/4" thick, and even then they shared it with all the neighboring towns. I knew people from small towns who thought phone numbers were four digits long, since the first three digits were always the same (and the then-optional area code was the same for probably a hundred miles).
When my family would go on trips we would visit "big cities" like Dallas, Houston, Orlando, Memphis, etc. (yes, I'm from the South) and in the hotel rooms I would notice that the phone books were always really thick. Like 4-5" thick. And sometimes, that was just the yellow pages, the white pages were an entirely different book, itself 3" at least. And they always had these awesome pictures on the front of the local skyline instead of the giant public domain "fingers do the walking" logo that would grace the phone book back home.
So consequently I made the connection early on in my mind that living in a huge city meant you were a success. And living in a huge city meant a huge phone book. Therefore, having a huge phone book in your home meant you were a success. A tenuous connection, but even then I had big dreams of moving to a "big city" later in life and one of these days I would have a big phone book in my house because hey, that's what big successful people living in big successful cities do.
Years and years pass. I grow up, go through High School, go to College, graduate, get married, and eventually my Wife and I move to the Dallas/Fort Worth Metroplex. We get good paying jobs and rent then eventually buy a house. Initially the phone books that would appear on our porch would be the same standard one-inch affairs I grew up with because we live in the suburbs and they only cover the suburbs, but then one day a bag with two phone books, a 3-inch white pages and a 5-inch yellow pages, shows up on our front porch. These phone books cover the entire Metroplex. They have amazing photos of the Dallas skyline, with Reunion Tower (the one with the ball on the end) on them (under a stuck-on ad for some ambulance chaser, but that peels off easily enough).
I'm elated. After all these years, I've finally made it! I'm finally in a good job making good money and living in a big city and hey, like all big successful people living in big cities, I have a pair of bigass phone books. I've arrived! Every time I look at these phone books I'll remember how I'm in a big city.
So I put these phone books next to the phone and the first thing my Wife says was "Just throw those things away. We have the Internet now."
I ignore the order and I keep the phone books under the phone cradle for a few years, exchanging them out when a new one comes in. I never tell my Wife the insanely silly "but I've always wanted a big phone book" fantasy because I'm not in the mood to get laughed at (though, apparently, I don't mind that people on Slashdot will laugh at me). I get to keep them in place with the razor thin "well what if we want to look up a phone number when the power's off or our Internet is down?" excuse.
But then one day I'm cleaning the house and I'm trying to reduce some clutter and it occurs to me that in two years I've never opened these things, ever, and they're just collecting dust and the odds of the power going out or the Internet going down at the same time as my cell phone battery dying and me having to have some obscure phone number are vanishingly small. Oh, and in the years since we moved out here we've switched to Vonage so we couldn't even use the phone in a power outage anyway. And I now have Internet access on my phone (hell my wife has a Treo) so if we needed to

Very computer-centric, and more particularly, very 1970-1985-computer-centric.
How about: making wooden wheels, for cars or carts?
Drilling holes in stone with a hammer and a stardrill?
Repacking plumbing/steam gasket seals?
Installing/maintaining lead/oakum plumbing?
Relashing valve pushrods or regrinding valve seats with a file?
Filing threads?
Making nails with a hammer and a header?
Making wrought iron?
Making aluminum without electricity?
Forming lumber with a froe, an adze, and a two-man saw?
Tanning leather?
And some of the items, I just flat-out disagree with: making a fire by striking two pieces of flint together? That *doesn't work*. You strike a piece of steel against flint, which throws sparks because the steel is cut by the flint and showers off bits of hot steel. Flint doesn't burn.
Nostalgia's not what it used to be.
What strikes me as astonishing about this topic, other than the fact that the majority of the discussion seems to revolve around the utility of assembly programming, is that the list itself displays a marked lack of understanding of the ongoing utility of low technology devices. For instance, one of the items listed is "Buttoning one's trouser fly". Perhaps the author of that idea has never heard of Levi's 501 Jeans? I submit that the 501's are some of the most popular trousers in the world, and the skill of buttoning them could hardly be considered obsolete. The rest of the list is rife with items that only the most technologically-blinded among us could possibly think of as obsolete.
Even the summary contains a dubious suggestion, "Changing the gas mixture on your car's carburetor". Perhaps the author is unaware of the vast numbers of motorcycles and small engines sold each year that incorporate carburetors?
"Cast lead bullets"? Thousands, if not millions, of ammunition reloaders would disagree.
"Changing vacuum tubes"? Millions of musicians would disagree.
"Darkroom photography skills"? "Developing photographic film"? Obviously, this person is not a photographer!
That's as far as I can get without becoming even more disgusted with the state of humanity, or at least the supposedly tech-savvy people who probably are contributing to this list.
