Dr Dobb’s Journal, 1976 - 2009

Back in the golden days of computer magazines (I’m talking the mid-80’s to mid-90’s), I could spend ages in the newsagent browsing all the different available issues. You remember – when the US PC Magazine was as big as a phone book, and it seemed like every brand of computer had their own magazines – BBC Micro, Commodore 64 and Amiga, Sinclair ZX Spectrum, MicroBee and the rest. One particular periodical that caught my eye was Dr Dobb’s Journal (DDJ for short) – probably because it wasn’t so much aligned with a particular brand, but that it was about computer programming in general.

The first issue I bought was March 1990, which had an assembly language theme. For old times sake, let’s take a trip down memory lane and see what those 160 pages included. Descriptions are as printed on the contents page.

The following feature articles:

  • Assembly language lives (Michael Abrash) – Assembly language isn’t the be-all and end-all of PC programming, but as Michael states, it’s sometimes the only game in town when performance program size are important
  • Assembly language tricks of the trade (Tim Paterson) – Every programmer collects a personal bag of programming tricks. Tim’s been 13 years in the making, and he shares some of his favourites with you.
  • 68040 programming (Stephen Satchell) – The newest member of the 680x0 family provides some challenges for programmers at all levels, particularly when it comes to caching.
  • Homegrown Debugging – 386 style! (Al Williams) – Use the 80386’s hardware to debug your programs by including Al’s assembly language code to establish breakpoints.
  • Managing multiple data segments under Microsoft Windows: Part II (Tim Paterson and Steve Flenniken) – Last month, Tim and Steve presented a method for managing multiple data segments under MS Windows using the segment table. This month, the provide a sample Windows program that puts the segtable library to work.
  • Object-oriented programming with assembly language (Randall Hyde) – Randy makes a case that the object-oriented paradigm isn’t completely the domain of high-level programming languages. He believes that OOP techniques can be applied, and are worth considering for ASM programs too.
  • Inside Watcom C 7.0/386 (Andrew Schulman) – Andrew suspects that Watcom’s C 7.0/386 has launched the opening salvos in a 32-bit 386 development tool ware. he also looks at how Novell has implemented the compiler for its C Network Compiler/386.
  • Mixed-language programming with ASM (Karl Write and Rick Schell) – As Karl and Rick point out, it’s not only practical but often advisable to mix languages and memory models in order to achieve the best results. Assembly language is a vital part of this mix.

the following columns:

  • Programming paradigms (Michael Swaine) – List has been codified, gentrified, and now objectified. Michael looks at how the Common Lisp data-type system underlies the object system, and how Lisp functions have been extended in the object world.
  • C Programming (Al Stevens) – TEXTSRCH, Al’s text retrieval project, continues to grow. Now you can select and view one of the files from within the TEXTSRCH program itself. he then uses this feature to explore the CURSES function library.
  • Structured programming (Jeff Duntemann) – There really were some neat ideas at last fall’s Comdex, you just had to search them out. Jeff describes the jewels he discovered, then delves into sets in Modula-2.

plus the following:

  • Editorial (Jonathan Erickson)
  • Letters
  • Swaine’s Flames (Michael Swaine)
  • Of Interest (compiled by Janna Custer)

Wow! A bit of a blast from the past! At $AU5.95 it wasn’t the cheapest thing on the shelf, but you certainly got your money’s worth. And yes folks, that’s THE Tim Paterson.

A few years later I started to subscribe and began my collection. What I’ve really enjoyed was the variety of articles. Whilst there was almost always something of direct relevance, it was the exposure to other languages, hardware platforms and specialty areas that I really liked. And you never know when sometimes something might actually be useful in your own field too.

Here’s almost all of my collection that I’ve accumulated over the years. Funny how other magazines and journals dated quickly and weren’t that hard to throw out, but I always felt that inside most issues there’d be something, if not timeless then at least worth keeping around for a while yet.

So the years passed, some things changed, but DDJ continued on. I did notice some differences – the page count slowly dropped, some of the columnists changed or finished, but Jonathan continued to be the editor and Michael’s “Swaine’s Flames” continued to be on the last page. Actually now that I look more closely, it does look like Jonathan and Michael ended up carrying most of the work towards the end.

I’d previously seen the same happen to BYTE magazine (to which I’d also subscribed to until its demise just over 10 years ago), and I suspected DDJ was heading in the same direction. February 2009 and my fears were confirmed by Jonathan Erickson’s editorial – DDJ’s time had finished, it was to become a monthly insert to Information Week. Ironically I received the early-January edition of Information Week in late February (not that handy for a weekly publication to arrive that late!) and the DDJ inclusion turned out to be nothing more than a column written by Jonathan. Information Week is aimed at “IT professionals and business managers”. Somehow I don’t think they’re going to be running to many assembly language articles anymore.

So let’s compare the final issue. From 160pages down to just 48. You can tell when a magazine or journal is getting smaller when they no longer print the title on the spine of the publication, because there isn’t a spine anymore (just staples). I’d guess the art budget must have also been slashed, as instead of clever/thought-provoking covers, for the last few issues we’ve been greeted with with photos of one of the subjects of the “Developer Diaries” page.

It contains the following feature articles:

  • Computing in the Clouds (Dana Moore and John Hebeler) - Cloud computing offers virtually unlimited, on-demand computing resources. Our authors examine how you can you can create cloud applications through Amazon Web Services and the Google Application Engine.
  • Software Development in the Cloud (Nick Gulrajani and Darryl Bowler) - Software development in the cloud brings adaptability and flexibility to any size project team.
  • Videos and Oracle Forms 10g (Greg Williams) - Greg shows how you can take advantage of unstructured data in the database - video, in this case - and access this data from Oracle Forms.
  • Parallel LINQ (Paul Kimmel) - Parallel LINQ, which is part of the Parallel FX extensions for .NET, lets you use basic LINQ keywords to tap into the extra power that multicore systems provide.
  • Decoupling C Header Files (R. Samuel Klatchko) - One issue with the common C compilation model is that it can easily lead to unnecessary coupling between files. But decoupling those files isn't necessarily easy either.

the following columns:

  • Effective Concurrency (Herb Sutter) - When it comes to lock-free programming, volatile is a volatile subject - no matter what name it goes by.
  • Disciplined Agility (Scott W. Ambler) - Package implementations look great from a business point of view but can easily run into trouble if the bureaucracy gets out of hand.

plus the following:

  • Friday Night Fish Fry (Jonathan Erickson) - Change happens as Dr. Dobb's steps up to the next level.
  • Alia Vox (Tieren Zhou) - Specification Driven Development is an agile development methodology with two deliverables: working software and product design.
  • Developer Diaries (edited by Michael Swaine) - Profiles of programmers, descriptions of developers.
  • Conversations (Jonathan Erickson) - According to Lori McVittie, cloud computing is a deployment model leveraging on-demand computing to scale and serve applications through a shared resource model.
  • Swaine’s Flames (Michael Swaine) - Michael wonders why if Twitter is so great, why do they have to promote it by e-mail?

Still some interesting stuff, but a shadow of its former self. Most of these articles are only one or two pages, contrasting with the detailed content from 1990. I see we also lost the “Letters” section at some stage. I reckon I finished reading the whole thing in 30 minutes.

I don’t know why it died, but you would have to guess that online media has a big part to play. There’s so much information online (a lot of rubbish, but some good quality too) that it’s probably hard for a paper-based medium that you’re charging customers for to compete against anything free. DDJ have been pushing their online content for a while, but

Farewell DDJ. Thanks for helping me be a better informed programmer. You’ll be missed.

Good Post Dave. I used to read those mags too.. I didn't subscribe though, so I was probably partly tyo blame for their demise..

I *did* buy lots of gaming mags in the same era though!
