How To Develop Unmaintainable Software 211

Posted by Soulskill from the just-do-what-comes-naturally dept.
jones_supa writes "Greg Jorgensen specializes in debugging, fixing, maintaining, and extending legacy software systems. His typical client has a web site or internal application that works, more or less, but the original developer isn't available. Greg lists some things you can do in your own software projects to keep him in business. In summary, the list goes as follows: Customize your development environment a lot, don't make it easy for the next programmer to start working on the code. Create an elaborate build and deployment environment and remember to leave out the documentation. Don't bother with a testing/staging server but instead have secret logins and backdoor URLs to test new features, and mix test data with real data in your database. Don't bother with a well-understood framework, write everything from scratch instead. Add dependencies to specific versions of libraries and resources, but don't protect or document those dependencies. For the icing of the cake, use the coolest mix of cutting-edge programming languages."

      lol, 25 years ago we had ONE programmer able to maintain our software as he had done much of the customization of an out of the box accounting system. Bloody thing was so complex to start with noone wanted to touch it before we fixed it up, much less afterwards. Upto 10 Megabytes worth of code but no more than 32K loadable in memory. Must have been 100's of small chunks of code all calling each other in and out of memory every other keystroke.

      I managed to customize some reports but that was only part i ever dared to touch.

      The real kicker...written in a version of BASIC.

      Actually a pretty impressive system and worked well for 15 years. Always wondered how they managed to write such a monstrosity. Kept picturing a blimp hanger with a flowchart wrapped around the walls.

It could have been replaced in 6 months by two dedicated programmers for far less than it cost to buy the rights to the whole thing in the first place, but only one of us was that dedicated.

        Well understood frameworks tend not to be highly optimized. If you are dealing with something where performance is absolutely critical, writing it 'from scratch' will probably get you better performance than taking one of those 'well-understood frameworks' out for a drive.

        Sure, of course, why not. It's not like your time is valuable or anything. And naturally, you will make this decision before coding starts, and thus before any measurements that the framework was actually slow, or for that matter that it was part of the perf bottleneck of the system. Nothing says "job security code" like elaborate cryptic algorithms to improve asymptotic performance of some in-memory task on a system where CPU never got above 5% in the first place.

        Let's not forget how bug free a framework used widely by thousands will be - there's no job security there at all if there's no bugfixing! But if we write our own, then there will surely be some horrific bug in the field that we can work until 4AM to fix, and management will call us heroes!

        The main thing, of course, when writing your own replacement for some common library that some new hire would already know is to avoid any documentation, and ideally abandon the effort halfway through, because the project ran out of time, only ever use 10% of what you wrote, and never document which 10% - heavens no!

        To make doubly sure that no new hire could ever support this code, remember to follow this key element of Abject-Oriented Programming: [typicalprogrammer.com]

        Documentation
          It's said that code should be written for people to read, so it follows that documentation is written for no one to read. Documentation should be written for every new module and then maintained as changes are put into production, or at least the next time thereâ(TM)s a lull in the workload.

        A good time to write documentation is when someone in the department gives two-weeks notice: use that time to make sure the departing team member documents all of their code.

        Cluttering up the source code with lots of comments explaining what the code is trying to do is distracting and slows down the compiler. That's why abject shops that follow "best practices" keep documentation in a document management system where programmers can't accidentally delete it.

        Sage advice, I'd say.

        Bottom line here is that this 'list' is just the logical conclusion of a career of mediocrity spent shifting blame around instead of working the problem. Real programmers can use anything

        Perhaps you missed the part that the author of TFA makes his living answering panicked calls to bugfix production legacy code, presumably because some "real programmer" did in fact "use anything", and this advice is based on long experience of what makes code unmaintainable. My own experience/advice lines up with his rather well in this area, I'd say.

          You devoted considerable effort to coming up with a response. Yet you failed in every way to realize that the point being made was that good programmers often depart from guideline, and with good reason. If this was less a list and more an advice column, then I wouldn't have picked it apart. But it comes off as a "dos and don'ts" list, and frankly... such a list has neither educational nor informational value.

          But whatever, if you want to continue down this path, okay then; Look smartass, you can't test a framework against your own hand-crafted code because you don't know how your hand-crafted code is going to perform until you build a prototype. So fucking duh, yes, the test happens after. And if you'd sat down on a whiteboard and stenciled out a block diagram of what your app, or at least the part of it you're working on, does... you'd already know which branches are going to be most used, and where special attention needs to be paid towards optimization. I already provided the caveat that where performance is critical. I'm not talking about business apps or databases when I say these things. I'm talking low level shit like how they're building switches that begin writing out a new packet while the previous packet is still incoming to gain precious milliseconds in high frequency trading. You aren't writing that with .NET or whatever framework you're upset I dismissed from consideration. PERIOD.

          Also "But if we write our own, then there will surely be some horrific bug in the field that we can work until 4AM to fix, and management will call us heroes!" is about the most moronic thing you can say. Management doesn't consider your project resulting in piles of overtime "heroic". It considers you a poor performer and will be looking to replace you.

          Look, bottom line here is that when you code professionally, you are engaged in a massive balancing act between deadlines, error checking, other people's contributions, etc., etc. Coding professionally is an organic process, and while everyone knows what the best practices are (documentation, QA, modularity, readability, etc.) these are ideals to strive for, not things we can actually achieve on every single project.

    Often it is how a project is initially managed that results in an unmaintainable system. A few simple mistakes can send a project straight to hell from the very beginning. A simple one would be to allow the senior management to firehose new features at the project far faster than the developers can build them. Another would be to allow the wrong people to pick the core components. That is how bad databases/languages/operating systems can be chosen. Then you get the next layer of wrong when people simply code and architect badly.

    OK .. no source code at all pretty much makes it difficult to maintain. Or not being sure if what is in use is the current code.

    As for the 'use a framework' .. what BS. Frameworks come and go. What is well used today can be a long forgotten, unsupported mess 5 years from now. Like NetBeans and Swing?? All those GUIs I wrote 5 years ago probably now fall into the 'unmaintainable' software category, even though all the code is actually there, and anyone that understands GUI programming at a basic level can still make modifications. It's not easy (i.e. not for the lazy), but it's possible. And how many times has a framework version made upgrading difficult because of extensive changes???

    It's OK to use Hibernate, ICE, and all that stuff that makes the job easier today, but learn how stuff actually works and only use it when necessary. It will make you more valuable in the long run, and the code more maintainable in the future.

    Use long looong looooooooong stored procedures (20,000+ lines long) with lots of spaghetti SQL code and very little documentation. And never use identities and primary keys; instead just get the max ID number on the fly and use source code to get the next integer-up for the next record insertion to a given table. Make sure the table and field names have almost no relevance to the data they hold. use views liberally, and query one view on top of another view on top of another view on top of another view. If possible try and work something out to where there simply isn't any relational design to the database at all, and instead just use redundancy everywhere. Or, if you really want to be nasty, you could go the opposite route and figure out some kind of a mindbending rubix-cube-like puzzle where there is only one table with only 3 fields in the entire database, and nearly all table data of any sort is stored in one field in that table, and just rely on a myriad of SQL joins to emulate the behavior of relational database design.

    How about "Set up a global int l and set it to 0, and a global int O and set it to 1. Or sometimes l, depending on what file you're in." This works better or worse, depending on your font. Or in C++, have every class inherit from every other class. I've seen this done.

    A couple times I've run across some jackhole who is in love with dynamic shit and who wants to check java object code into an SQL database and dynamically load it into a program. Nothing quite spells fun like wondering where the hell the code is branching to, and spending two days figuring out it's to an object in a database the code to which has been lost 4 years earlier.

    For a long time there in the '90's and a bit later, version control wasn't a normal thing. If you had to get management approval to set one up, that usually would start up the sinking feeling about that job sooner rather than later. Nothing quite like having to justify the addition of something they should have never written a line of code without in the first place. Nevermind trying to get overhead for writing unit tests. Assuming unit tests are even possible. For most of the projects I've run across, the coupling is so tight there's no way to get in and test discrete functionality of anything.

    For the guys not using version control, "Lose the source code" is a good one. You don't even have to be malicious about it (Though malice helps.) Just build the thing on your personal dev box, deploy the executables to production and never mention it when you leave. Bonus points if they walk you out during a layoff.

    "Don't set up a build system" is another good one. Gotta love those projects where you have to run a top-level build three times before it produces an executable!

    At one organization I inherited a fund-raising database developed with much arrogance in Filemaker Pro. Except that the FMP "Guru" quit in a huff when it was only about 2/3 functional.

    Despite this the thing was used - with many, many crashes - for two years because it was the best thing that they had. And because Mr. Guru was a pal of half the staff.

    Did I mention that Mr. Guru also refused to hand over any of the logins that would allow someone to fix or administer this thing?

    We eventually wound up moving over to MS Access (GOD YUCK EVIL!), and massaging, fixing, cleaning, importing ten years of data, each year on a different format, file type, or with different fields. We actually managed to turn it into a reasonably useful fund raising tool. I mean, aside from the downside of using MS Access.

    Documentation goes out of synch with the code very quickly. The only thing worse than working on someone else's code without documentation is working on someone else's code with incorrect documentation. The problem is so old Dijkstra allegedly said, "Always debug code, not the comments".

      I think you can also document in a way that is also up to date. For example, do you document the who/what/when/why for version commits? Sure. Do you put in-line comments in the code, e.g. "We need to revise the code below at some point to account for ABC"? I hope so. Do you have a stash of reference scripts/how-tos so you don't have to reinvent how to do semi-routine complex actions, like deployment?

    As long as you document, label and organize your code coherently and logically in a solid language, coding from scratch (or near scratch using libraries of your own) can be a good thing. It avoids pitfalls like vulnerabilities that affect common code bases, massive libraries that take friggin' *ages* to load on an i7 with a fast internet connection or relying on the developer(s) of library X to add feature Y ("sorry, we can't add that feature yet Mr. Client, it's uh ... because of complicated programming reasons, basically, we're relying on a third party and we don't know how to do it ourselves")
