summary | Great insights into programming, software in general and how to do it right. |
The essays in this book are even-handed. While he focuses on Windows, Spolsky is not a fanatic believer in one approach over another; if C# works better than Visual Basic for a specific task, so be it. His approach is refreshing when so much is written by opinionated members of the "Microsoft is the source of all evil" camp.
Spolsky starts with down-to-earth topics, such as how to estimate the length of time programming tasks will require, and the ratio of QA people to developers needed for a healthy product. He then moves on to share his thoughts on managing developers and higher-level software-related issues.
One of the book's opening salvos, "the Joel Test for Better Code," is a simple "irresponsible" test that Spolsky created to provide insight into how well a development organization is functioning. The test looks for things like using source-code control, and having testers create daily builds with a single click of a button. As someone who has worked companies that would have failed the "Joel Test" miserably, I can attest to the importance of these criteria.
The chapter on Unicode is a short and to-the-point overview on the topic and should be required reading for any software developer and product manager who wants an introduction to Unicode.
Clean and bug-free code is a common thread in several essays in the first part of the book. Spolsky explains the inappropriateness of developers performing QA and stresses the need to "eat your own dog food." Having developers conduct testing is a waste of resources and upsets them just the same; forcing developers to use their own product will motivate them to create a better one.
In "Fire and Motion," Spolsky takes issue with the "architect astronauts" who generate vague technology announcements that are often counterproductive by creating fear, uncertainty and doubt. While these announcements may drive competitors to waste cycles in converting their code base to the latest technology, they offer no real substance. Misguided companies, mesmerized by the promise of new technologies or by demands from numskull customers, can sap years of developer time when product improvement should have taken precedence.
In "Biculturalism," Spolsky dispassionately discusses the differences in world view between Windows and UNIX programmers. Spolsky probably rankled some UNIX fans, but I share his perspective. Spolsky points out that UNIX developers are just as smart as Windows developers, but when it comes to understanding their end users and having empathy for customers, they tend to fall short.
The "Gorilla Guide to Interviewing" is relevant to all hiring managers. Spolsky describes some of the traits of his ideal hires. Those who, in one sentence, are both smart and "get things done." Spolsky believes in hiring people that can perform multiple roles. Spolsky believes in making a "sharp" decision about the candidate, and finds insulting that a hiring manager would not find the interviewee good enough for his own team but would refer him to another team. Spolsky shares one of his hiring secrets: never hire a "maybe." This might seem obvious, but he details why it's better to reject a good candidate than to hire a bad one. Firing can cost a lot of money, time and effort. Additionally, Spolsky suggests questions to ask during an interview and the necessary "what not to ask."
The "Iceberg Secret Revealed" discusses the manner in which customers express their pain, and points out that customers often don't really know what they want. It is the product manager's job to find a solution that will solve their customer's pain while keeping an eye on the market she is addressing. Just listening to customers without proper filters, is as Spolsky points out, a recipe for disaster. And the Iceberg Secret? Spolsky illustrates in five different ways how customers and stakeholders only look at the tip of the iceberg, and not at the substance beneath it.
In one of the shorter chapters, a missive on measurement, Spolsky addresses the prickly issue of measuring performance in companies. In addition to his own insights on measuring performance, he recommends Measuring and Managing Performance in Organizations by Robert Austin. I will add that to my reading list.
Spolsky wrote an introduction to In Search of Stupidity . He offers there the "geek's" perspective on what it takes to make a successful software company, taking as a starting point the ten largest software companies in 1984 and the equivalent list of 2001. His conclusion is that "no software company can succeed unless a programmer is at the helm." With his usual even handedness, he is quick to point out some of the debacles programmers are responsible for. In the example he gives, Netscape's disastrous rewriting of their code base and almost complete loss of market share while they were doing it. His bottom line? To succeed, a company needs a management team that love and thoroughly understand programming and understand and love business. Not as easy as it sounds.
In his five "Strategy Letters," Spolsky writes about issues that are relevant to anyone making strategic business decisions in the software industry. He starts with company growth modes by comparing Ben & Jerry's to Amazon. He then discusses the classic "Chicken and the Egg" problem when building new platforms. His example is still relevant -- few will develop .NET-based clients until a large number of end users have the .NET engine installed on their PCs and end users will not install it until there are enough applications that require it. Spolsky moves on to discuss backward compatibility, open source economics and the myth of bloatware.
Spolsky points out that despite the growing size of applications, the cost of disk space has plummeted even faster. This may be true, but Spolsky does not address the programs' resulting sluggishness despite more and more processing power. Spolsky wraps up the essay by dismissing the notion of coming out with a "lite" version for a given software product. I agree that lite versions do not always satisfy everyone, but they can be a great way to keep out low-end competitors from entering the market in addition to a way to introduce customers to the high-end product.
The chapter about Microsoft losing the API war is a classic. Spolsky starts with the seemingly outlandish assertion that Microsoft lost the API war. After apologizing for his "grandiloquence and pomposity," he goes on to build a convincing case that if Microsoft has in fact not lost the war, they are definitely in danger of doing so. He starts with the diminishing interest in the Windows API as a development platform. He then describes how two camps inside Microsoft (the "Raymond Chen" and the "MSDN Magazine" groups) are influencing Microsoft's approach to their developers' tools. The former group emphasizes creating a backward-compatible operating system, free of bugs and impervious to third-party applications' errors that can harm it. On the other hand is the MSDN group, promoting the latest and greatest Microsoft has to offer. As Spolsky sees it, the latter group has the upper hand, and because of this, Microsoft is losing their developer base to simpler, more easily deployed platforms.
In part 4 of the book, Spolsky takes on Microsoft's .NET strategy. He describes Microsoft's tendency to create FUD in the marketplace with vague, hollow statements, and details his own company's reasons for not adopting .NET anytime soon. Spolsky wraps up with a very straightforward feature request: a linker for .NET. This would seem to be an obvious feature, but Microsoft so far doesn't agree. Microsoft is acting as though they want to win the development platform war in a single sweep. At the same time, independent software vendors (ISVs) are resisting, because they have to guarantee backward compatibility and support for everything their customers run.
My only complaint about the book is that it's too short. On my bookshelf, it resides next to the Mythical Man Month, another favorite.
Spolsky is knowledgeable, funny and free of unnecessary religious fervor. Joel on Software is a must-read for developers, product managers and those who want more insight into the world of developing software.

Politics are orthogonal to software indeed, why don't you follow your own goddamn sentiment Joel.
Having worked a ton of jobs as an electrical, hardware, and software engineer I can tell you that this generalization makes absolutely no sense. In general, there is absoultely no macroscopic correlation between software usability and underlying operating system platform. Software development is such a complex process, and for anything other than some shitty little bug tracking tool, one that involves more than a few people. How these teams are managed (that ranges from methodology, to choosing the smart/professional people in the first place) has absolutely nothing to do with some UNIX/Windows dichotomy you're promulgating. There are of course the zealots, of which you are a Windows/Microsoft one, even if you don't realize it. This is from the fact that you draw this simplistic separation, no matter how charitable you are about the other side.
When you get out of the realm of the shrink wrap software market from Best Buy, you realize there is a huge multi billion dollar industry of software used for things like manufacturing and design, and no Joel, they're not all programmers tools.
For many segments of this market, the operating system used becomes a secondary issue to having an integrated or working system.
For a high profile example, there was the LAX shutdown due to the shitty designed Windows based ATC system. Apparently, according to you, at least the developers had empathy for the poor bastards flying to LAX when their shitty system didn't work. The fact of the matter is that this could and probably would have happened if the same team of idiots had chosen to use a UNIX system. It is not an issue of smartness or UNIX people people being as smart as Windows people.

Joel is no idiot. He realizes that specifications take time and effort to develop, and to keep up-to-date. He argues quite convincingly for specifications as a wise investment of time, not a waste. A large section of this book is devoted to "painless" specifications, and it is insightful and useful. This book is the only book I've ever felt a need to keep next to my keyboard - and it's not even a technical manual.

That's a fine anecdote, and an unfortunate experience, but it's not proof that specs somehow save you from this problem. You were clearly deciding how things work when you built the code, so decisions got made. If those bad decision

And I even have an experience that went like this: the client actually nominated one person to represent him and make the decisions for him. The ideal situation, right? So we go ahead, and even accept a ton of change requests from him, and conversely he aggrees that extra time is needed to implement those. Also that some features that needed the most time weren't that necessary and can be left out for now. Had some iterations with him too. All went smoothly.
So then here comes the big day and deadline and have to get the program accepted and paid. And the client PHB gets in the act and overrides the representative. "What? You threw away _that_ feature I explicitly requested myself in the beginning?! On whose authority?! And why the heck is this program two months late?! I needed it in March!!" (The two months had been accepted by his representative as time to implement the change requests.)
Turns out the peon nominated to represent him didn't have as much authority as he and we thought. And not having anything written down and signed for all that stuff in between, well, basically his view was that we went into phantasy land and implemented something else than what he asked for. Two months late too.
"No development method can save you if complete idiots are in charge."
Quite insightful, but therein lies the rub: development without any specs and just doing what the clients fancy this week, basically puts _them_ in charge. They're your new managers, they decide what you do. And they're not even trained or experienced to manage a programming project. How do you prevent half of them from being complete idiots?
Basically I'm not against iterations as in showing the the client some progress. But I do like having _some_ specs, if nothing else to prevent wasting even more work.
True, the client doesn't know exactly what they want from the beginning, and just writing all down will make the bad spec that you mention. But here's the fun part: you can help the client give you a good spec. Mock-ups and small demos take a lot less work than actually coding those features, and lets them see roughly how things work and kill dumb ideas just the same.

Ah, more XP bullshit and double-speak.
No, XP merely redefines the meaning of the word "bug". If it's not in an automated test, it's not a bug. Even if the client's data is pwn3d by an

I believe that's already explained in Kent Beck's books very clearly. It's based on redefining semantics so that "bug" suddenly means what everyone else calls "known deffect".
Funny thing is, Microsoft too ships with no known defects as a matter of policy. By XP definition (again, Kent Beck's definition) all the buffer overflows and exploits that pop every weeks are therefore not bugs. They're at most change requests and

'First of all, failing to write a spec is the single biggest unnecessary risk you take in a software project. It's as stupid as setting off to cross the Mojave desert with just the clothes on your back, hoping to "wing it."'
I don't think you are really justified to call the guy an idiot with your single, most likely very out of context, quote. Here [joelonsoftware.com] is where I got this quote.
